I used to dread the idea of going to a gym, but this place completely changed my mind. It has the most incredible comfort vibes—it honestly feels less like a big, intimidating gym and more like a genuinely welcoming and supportive space. There’s zero pressure here, and the atmosphere is so easygoing.

For a beginner like me, the equipment selection is perfect. They have all the modern, quality machines you need, and they're simple to figure out, so you never feel lost or confused about what you should be doing.

But the real game-changer here is Keith, the personal trainer. Seriously, if you need guidance, he is absolutely amazing. He radiates positivity and made me feel totally at ease from day one. He breaks down every workout so clearly and makes sure you feel strong and confident, never judged. He’s truly the best part of the gym.

If you’re looking for a fitness spot where you feel instantly comfortable and completely supported, this is it!

Stronger, Healthier, and More Confident Thanks to Prime Fitness.

I joined Prime Fitness about 4 Years ago, and it's easily one of the best fitness decisions I have ever made. From the moment I walked in, the welcoming and motivating environment stood out.

The trainer I see, Keith, is incredibly knowledgeable, supportive, and detail-oriented. He takes the time to understand your goals and adjust each workout to your needs - whether it's building strength, improving endurance, or recovering from an injury.

The gym itself is always clean and well organized, with quality gear and a setup that makes training efficient and enjoyable. I love that it never feels crowded and that every session feels focused and personal.

If you're looking for a private, professional, and a results-driven gym, I can't recommend Prime Fitness enough! It's worth every bit of your time and investment.

Keith is the absolute best!!! This is the gym to go to in San Diego. I often work very strange hours, and the 24/7 access makes it super easy to keep hitting my fitness goals. I've been weightlifting for about 4 years at this point, and l've certainly passed many plateaus since joining Prime. I think it's mostly because I'm really able to go whenever I want and I never have to worry if equipment is being taken up or used by somebody else since there are few people at the hours I go! There is also definitely the right amount of equipment. It doesn't feel cramped, but I also don't ever feel like they don't have something I need. The outdoor area is a huge plus, too. I've also never had a bad interaction with anybody while at Prime, which is awesome!

Great gym and super convenient location! Especially if you’re new to weightlifting machines like me. The personal training from the owner here really helped me feel more comfortable using the machines and incorporating weights into my workout, which only consisted of yoga before joining.

Updated Review (10/1/2025): After one year under Keith's personal training services, I find that I progressed far more than I ever imagined or expected. I have friends noticing my results, and having someone as knowledgeable, patient, and attentive as Keith has really started to pay off. This gym is also baked into my routine, and I find that I am able to complete my workout peacefully and without fighting for machines. I am looking forward to further dialing in my workouts and nutrition under Keith's expert guidance to put on more muscle mass and getting summer body ready for 2026.

Previous Review (10/1/2024): Prime Fitness is an excellent, well-maintained, gym that offers everything you could need to get in a good workout. I hardly ever have to wait on equipment which is a big plus. The flexibility in hours also helps me get in a workout when I need to.

On top of that, Keith’s personal training services are bar none through his attentiveness, calm presence, and focus to make sure his clients are set up for success in a sustainable manner. I have gained a bit more muscle mass in the past 3 months working with Keith and following his workouts. As we have worked together, he continues to dial in where I am at and push me when I have needed to be pushed. I look forward to many more training sessions with Keith, and highly recommend his services to anyone looking to push themselves physically and mentally to new heights!

Going to Prime Fitness is fulfilling, rewarding, and just plain-old enjoyable. While the main reason I go there is to improve my strength and coordination using free weights and fitness machines -- and the selection at Prime is top-notch -- what I like best about the place is the low-key vibe and the fact that the gym's layout easily accommodates everyone who is there at any given moment. Since there is excellent redundancy in the equipment, there is never a wait to use the weights or machines -- I simply switch over to an alternative set-up and easily accomplish everything on my day's routine. I distribute my whole-body work-out over three days: push day, pull day, and shoulders-and-legs day. So comprehensive is the gym's array of equipment that there are still machines that I have not yet tried, leaving plenty of opportunity for future experimentation.

The other factor that contributes to the gym's welcoming ambience is that it is a neighborhood gym. Everyone going there seems to pick up on that, making it easy to meet fellow gym-goers and establish an easy rapport with others who are interested in fitness and self-improvement. I've met six people who live on my street, including two who live right in my building. People are friendly and, when asked, are eager to share their own tips and pointers which have helped them out in their journeys to better fitness. No attitude or haughtiness here, just a chill vibe that lends itself to working out hard and making progress. There's a nice balance between members' respecting others' independence and an enthusiasm to talk about what has worked for them in weight-lifing routines.

The place is clean, the equipment is solid and well-maintained, and Keith, the owner, is always ready to offer useful information about virtually any aspect of weight-lifing, cardio, or all-around fitness. Going there is one of the best parts of my day.

Location, equipment, great atmosphere, and dedicated gym-goers, this place has it all. I couldn't recommend it more highly. Defiitely 5 stars.

I was a member at Prime for 6 months. I always paid on time, followed the rules, cleaned and made good use of the equipment, and was respectful to other members. Despite that, my membership was abruptly and arbitrarily terminated by the owner after one unintentional incident on a machine — an accident I immediately apologized for and took responsibility for.

The owner prides himself on the fact that the gym is plastered with “no slamming” signs, and I always respected that. I am not a weight slammer. The owner, however, framed my ONE accident as me “allowing the weights to drop,” claimed it was a “second instance,” and decided that my “training style” was not compatible with his gym — something I find very discriminatory and diminishing. He also implied that I belonged with “customers wanting to slam weights [who] will be asked to go elsewhere,” and mischaracterized an accident as intentional slamming. In the same message where he made the one sided decision to terminate my membership, he wrote that the incident disrupted the gym -and I quote- “but specifically to the client that is paying good money for the service that I am providing.” This makes it crystal clear that to him some members are considered more valuable than others.

He also said he had “given me a previous warning,” which clearly reflects a management style focused on warnings and judgment rather than creating dialogue with customers or giving them the opportunity to be heard when unintentional incidents/accidents happen. At Prime, the approach is completely arbitrary and punitive.

Other reviews report the same issues: passive-aggressive signs, unreasonable enforcement, and especially dirty facilities. My experience unfortunately confirms that pattern.

Prime Fitness 24/7 in Hillcrest is truly one of a kind, and that’s thanks to Keith, who runs the gym with kindness, integrity, and genuine care for his members. What makes this place stand out is the community Keith has built on trust and respect—you won’t find that at most gyms.

The equipment selection is excellent and thoughtfully chosen so you can hit every muscle group. No matter your fitness goals, you’ll find what you need here.

When I lost my key fob, Keith went out of his way to cover a third of the replacement cost out of his own pocket. As a college student, that small act of generosity meant the world to me and showed how much he values the people who come through his doors.

The gym itself is fantastic, but what really sets it apart is Keith. His approach makes fitness accessible, welcoming, and community-driven. I can’t recommend Prime Fitness 24/7 enough—it’s more than just a gym, it’s a place where people feel supported.

In addition, the other members are so respectful of one another. No one is dropping/pounding weights, almost all make sure to wipe down machines after use, and there is very little wait time to use your preferred equipment.

The facility is SPOTLESS clean.

No matter when I/we have gone to the gym, finding parking has never been much of an issue. I'm an early riser, and usually there well before 6am. Parking is very easy, and there are usually only a few members there at the time.

My daughter and son-in-law found this gem of a gym a few months ago as soon as they moved into the neighborhood. This weekend, the owner was kind enough to let me use the gym while I was visiting my daughter for a couple of days. I watched the owner in action as he was guiding another newcomer to the gym. Very impressive, thoughtful, friendly and safety-first approach. This is a perfect no-pressure, family friendly, well equipped, clean, always-available gym, whether you are a newbie, just looking to get in shape or a serious athlete with tough goals - they've got everything you will need.

I like working out here for the most part, the gym is clean and has a nice selection of machines. It’s not overly busy most of the time.

The gym is hot for me (80F) a lot of the time. I need low 70s to get a good workout in or else the heat strains my body. No AC in the gym, just 2 fans and a couple propped doors.

The equipment is a little squished together. Like when you do leg raises by the front door, people can open the door into your legs while you’re on the machine.

Equipment is old and dirty, but the real problem with this place is the owner, a prissy, passive aggressive and unreasonable man. Whenever you are at the gym you have to be extra quiet because there’s a business upstairs. Which leads to the question, why did you open a gym there? The walls are plastered with passive aggressive notes telling you that if you so much make a little bit of noise then you should go to 24h fitness. It's a pity because this is the only 24h gym in the area.

I've been doing weekly training with Keith since February 2023 - right after I turned 35. We'd welcomed twins in Dec 2022 to go along with our toddler and between lack of time and lack of sleep I'd been gaining weight and feeling worse for months.

My strength, appearance, and overall fitness have improved significantly in just 5 months of committing to making our weekly workouts and having Keith as an accountability partner. I don't get muscle strains from getting out of bed, I see definition in new places, and my pants fit much better as I'm down 10lbs. My wife is appreciative as well.

I'm grateful Keith chose to take me on as a client since he doesn't work one-on-one as much anymore, but his ability to customize each workout depending on my various aches and levels of sleep deprivation has ensured that I've made steady progress.

Prime isn't for everyone - there aren't a bunch of superfluous amenities for newbies who don't really want to workout, and it also doesn't cater to the powerlifting / weight dropping set. But if you're looking to shake off that rust and get to the next level, this is the place to do it!

Walk ins not welcome.

I went to the gym using Google maps at 5pm. Main door is locked, I could see side door open so I went to the open door and asked the nearest person if there was a member of staff who i could sign up with. He brought me to the owner in the gym.

The owner accosted me for trespassing when all I did was ask if there was a member of staff to pay to use the gym.

Equipment looks limited and old. If you’re a visitor in San Diego avoid this one

This business has not responded to my inquiry (It has been 2 weeks now). There is no information about pricing on website. I guess they pick and choose who they want to work with. Their website is not fully secured (Google says). 2 weeks later , no one from this place bothered to contact me. It shouldn't take 2 weeks whether you choose to be contacted by phone. Owners response below my review seems combative. They sure are quick to respond to a negative review, but can't respond to an inquiry? Owner has made no effort to contact me or have anyone from this place respond to my inquiry, probably because they don't like this review.

I've been going to this gym for about a year, and decided to throw this review out as an update now that it's moved to a new, larger space. The short version is that I agree with many of the positive comments here, and while there is more room in the new place it has not really changed the small gym culture. The diversity of people who work out there - there is a good spread with regard to age, gender, etc. - has I think prevented a gymbro culture or any particular dominant vibe from taking over. People are considerate, as you have to be to get by in a small gym; anybody who throws weights around or screams will tend to stand out and quickly adjust their behavior or find a different gym that better suits their taste.

I would also add that while it really is quiet at some times, as some other reviewers have suggested, it really depends on what time you go in. If you prefer to have people around to stay motivated, as I did when I was younger, you can go in during certain peak hours and reliably find enough people there. So you can really adjust the experience to what you are personally comfortable with, which is something I appreciate.

Edited post: Keith has moved to 1st avenue a much bigger space with plenty of equipment, an outside space and changing rooms. This guy is going place and I wish him all the best in the future!

I'm new here but so far so good. Plenty of weight machines to utilize as well as cardio equipment. Focus is on weight training I would say.

Prime fitness has everything you need and more! The best part about the gym is the 24 hr access and how quiet it is. Truly the complete opposite of the 24 hour fitness type places out there. I have never been in there with more than one other person (and usually I get the whole gym to myself!) Highly recommend to anyone who doesn't want to fight over a squat rack or dumbbells!

This is a real gym. A little cramp but worth every penny. This is the gym dream of a personal trainer who is kind enough to allow the public to use his facility at all hours with the rules of being honest, clean and respectful. Seems easy but other gyms lack every one of those common sense type behaviors.

This gym has everything you need if you're serious about fitness. It's not huge but it is clean, never crowded, comfortable and well equipped. With the fob entry it is safe, secure, and access is available 24/7 to all members. The vibe is friendly, but for those who are serious about working out and not there for a show. The owner is in great shape and will gladly explain how to use a piece of equipment or offer diet plan / nutritional help and advice. Private parking lot, parking is never an issue. Highly recommend if you're looking to get in shape and need a safe and comfortable environment.

Despite the small space, the gym itself is quiet and rarely crowded. 24 hour access is nice. Nothing fancy but everything you need. Only issue I had was with the policy around propping the door open when it’s hot.

I arrived to the gym where the temp was around 80 degrees and the fans were off. It was just myself on a Sat afternoon so I decided to kick on the fans and prop one door open to allow for airflow since you’re not allowed to change the AC setting.

Toward the end of my workout, the owner came in and asked about the door. I told him what I did and he preceded to tell me that my membership was revoked because the door isn’t allowed to be open unless he’s there.

He stated it’s because anyone can just walk in, which I understand but was shocked at how after explains how hot the temp was when I came in the hour before, he simply said “well the temp is at 72 now, I can’t imagine that it cooled off that much after you opened the door”.

I knew it was pointless to drive my point across with that attitude and handed in my fob. Wonder how things will get in the summer time if someone decides to workout when he’s not there, do they just suffer through it? Ridiculous policy

Keith is excellent to work with, and always responsive.

Great location, and never had an issue with parking.

My experience with Prime has been and continues to be perfect. Convenience at its finest. A special shout out to one of the trainers Brad. He’s always been very welcoming, kind and generous. I’m usually anti social when working out but when I see Brad I’m always more than happy for a convo!

Prime Fitness is an amazing gym. Despite the space, it has everything one needs including machines and free weights. The 24-hour access is very convenient so one can time their workout to fit their schedule. And for this reason, I've never been to the gym at a time when there are 5 more people beside me and I've never had to wait for a machine.

Keith, the owner, is absolutely amazing. He's always been super helpful and friendly. Brad is an instructor here whom I work out with from time-to-time who, also, is amazing. He's organized, knows what he's doing, and keeps in touch with you to make sure you're following your routine and have your calorie intake in check to achieve your fitness goals. I had been following online programs with slow and little progress, but since joining the gym and working with Brad, I've been able to work on a program that suits me.

Never worked out in a gym before. Keith was really friendly, and set me up with a personal trainer Jermaine to help me learn how to lift properly. That was a few months ago, and I have gotten some great results since then by following Jermaine’s excellent advice. People who haven’t seen me in a while ask me what I’ve been doing. I look forward to going to the gym everyday because of how chill of an environment it is, and how Keith and his trainers are so supportive.

This is the best gym you can find in Hillcrest. Small business, not crowded, and it has all the equipment required to train. I have been working out with Keith, the owner, for the past 6 months and personally I feel that he is the best trainer one can find in San Diego. He is very knowledgeable and patient. Very meticulous and follows up with you through out the week regarding your progress. I was looking to get into shape when I first started 6 months ago and Keith helped me transform my lifestyle. He works with you in tailoring a diet suitable for your lifestyle. I think the diet along with his programming helped me greatly in my progress towards being fit.

Keith, the owner, is truly passionate about helping you get to or stay at the level of fitness you want, and he lives and breathes this, hand-picking his trainers who also share this passion. Working out at Prime, you know that you are in the care of true professionals, with a high level of experience and a track record of success for their clients. Even if you don't work out with a trainer, Prime makes it easy to get your workout in and get on with your day.

Local, Safe, Affordable - Value Fitness at its Finest!

It all starts with Keith, the owner. I've been with Prime1 Fitness, since it was newly opened. Keith, picked a stellar spot nestled into the Hillcrest community to serve as a less corporate, community friendly gym.

He installed 24/7 surveillance cameras inside and out, to protect patrons and monitor their belongings. I can confidently say, this is the safest gym, I've ever been to.

Super affordable for the value. No Sign Up Fee, No Cancellation Fee, No Annual Renewal Fee. Just and honest, month to month membership. Why can't more gyms subscribe to this model!!!

Best of All - there is minimal staff, no check-in counter and 24 hour access to the facility with the use of a FAB key. If I ever needed anything from Keith, he was always a call or text away.

Affordable Prices and Excellent Service - this is easily the best gym experience I've had to-date in San Diego.

P.S. The scale, size and scope of different lifting equipment out matches any corporate gym in San Diego. 5/5 Recommend!

I'm glad I chose Prime Fitness as my gym. I have had very bad experience with those big brand gyms that are always packed, where the staff is not really helpful and that just care about your money, I've read about Prime Fitness, decided to give it a try and I'm happy I did it. Since it's open 24/7 you can workout at any time, and mostly you ll workout by yourself or with very few people, which means you won't need to change or adapt your workout, you ll be able to perform on your own pace. Besides that, it has nice equipments and you can always add some nice exercises to your workout. No matter what time of the day you ll go, you ll be able to keep a quality workout. Keith is a nice and helpful guy, always helped with anything I needed. Highly recommended.

I've been going to Prime Fitness for about a month now. I started with a trainer, Brad, who is awesome. He built a road map for my goal of losing 20 pounds in 3 months which includes workouts and calorie goals. I'm proud to say I'm well on my goal and I couldn't be where I am without Brad and Prime Fitness.

It is never busy after work so I can get my workout in without worrying about machines being busy for long periods of time. The small community is great as well, zero intimidation factor.

The gym is 24/7 so it is available whenever you need it, day or night. I am glad to be a member of Prime Fitness and encourage all to just stop by and check it out so you can see for yourself how great it is. Take the leap!

If you're looking for a clean gym, with a thoughful layout and curated equipment, you've found it at Prime Fitness Training. Some call it a neighborhood gym for it's convenient location, helpful and respectful trainers and the feeling of community with all members. From a strict weight driven workout to starting on your fitness track and everything in between, this gym will accommodate your fitness level.

Keith, owner, trainer and proud to call my friend, was my personal trainer for over 3 years. What makes him so extraordinary as a trainer is his passionate, knowledgeable, intuitive approach to training. He has dedicated his career to fitness and helping his clients reach their personal goals.
He is an avid student and continues to educate himself and perfect his craft in new creative and innovative ways. He walks the walk with his personal workouts and is always looking to raise the bar on his successes.
What I appreciate the most about Keith is his patient, authentic approach to training. The equipment is great, but it's his personalized and unique programs that yield the best results. I always felt that he was genuinely invested in my success. He surrounds himself with the same caliber of trainers and knows that he can help you reach and surpass your goals and the vision you have for yourself. Happy training!

He's put so much thought into the equipment and layout of the gym so that anyone can get what they need from it.

Where to begin, I have been with Prime Fitness Training for 4yrs now & haven't looked back since. Keith's first observation of me was that I was, "skinny fat!" Lol Although I was put off at first by this, I didn't realize that this was the type of forward treatment that was needed for me to begin my type of self improvement. For my reluctant self, it took a few attempts to begin & with continuous reminders from Keith encouraging me to push myself, I powered over those hurdles & began this marathon of an adventure. Results were showing reminding me everyday why I was doing this for myself. Now, not only have I reached my goals, I have created new ones.. Overcoming new challenges & only thankful to have this amazing Trainer & friend in my life. If you're reading this review & looking for a change. I 100% recommend consulting with Keith to have him take you to those next steps in improving ones self. He will motivate, drive & push you to be a better you :)

I have been working out with Keith Diedrich, owner of Prime Fitness Training, for 18 months now, and I have made impressive gains in my strength, fitness and stamina. Opening his own gym with personally selected equipment has made my workouts even more rewarding. All of the equipment is easy to access and designed to give a full body workout. I love the 24-hour access. It's not a big box gym but it is spacious enough to be comfortable. I've never had a problem with parking. Anyone looking for a gym should check out Prime Fitness. Talk with Keith about your fitness goals. He is very knowledgeable about fitness and he practices what he teaches. I know because I'm an example, an almost 68 year old example.

The location is great -- on Washington across the street from Bronx Pizza. The free parking is a huge plus; no two-hour limit so you can take your time in the gym. Great equipment in a nice space; gym is always very clean and people are friendly. The training is what makes this gym stand out from the crowd. Keith uses a variety of techniques to challenge you and gets results. I went from 22% body fat to 10% in 12 weeks this past year. I didn't think that was possible at my age (46).

Great place to work out! Keith is a great trainer. I have lost about 35lbs and can finally wear a bikini again.
The gym itself is a nice space. The colors seem to give me energy. The bathroom is spacious and there are lockers. There is a filtered water dispenser, and 7-11 next to the gym if you forget anything. The gym has a high ceiling and padded flooring with a mix of sealed concrete. Very cool.
Keith will let you play any music you'd like during your work out. The gym has numerous new machines and weights. There are also lockers available. The gym is never crowded and has all new equipment, is clean and orderly.
Keith and I (as well as my husband) have been working out together for about 2 years. During that time he has taught he discipline, as well as given me nutritional advice and work out tips. Thanks to Keith I now know how to use various gym equipment, and I understand pulse and blood pressure.
Keith is a patient person and will not complain, nor will he ever raise his voice or criticize you. He is a great person with seemingly endless bits of fitness and nutrition information. He will gladly help with a meal plan.
I highly recommend Prime Fitness and Keith as a trainer if you're looking to lose weight, get in shape, and learn self discipline.
