I had a conversation with a friend around Oct 2024 about starting a bootcamp. I felt what I was doing, which was mostly cardio and walking, was not enough. I still had unwanted weight and pain even after what I felt like was endless walking. I was very intimidated by any bootcamp, CrossFit, group strength classes. I never know what to do. I always feel like it’s not working. Finally in June 2025 I decided to do it. This gym has changed my life! Jenn and her “assistants” are very helpful. Always willing to show you (again lol) how to do do the workout effectively. I also pick the station with the least people, but many of the gym goers are friendly and do not let you work out alone. It’s very family friendly too. If our schedule changes and my husband cannot stay home with the kids or take them I don’t have to stress about missing my class or finding a sitter. It’s honestly the best feeling to not have to miss a.class because of no child care. Sometimes my kids beg me to go. So there really is no excuse! I am not were I want to be, but I know I am getting there. I never want to miss a class. It’s all because of this gym!

I am beyond thankful that Master Trainers was recommended to me! After having kids, I really struggled to get back into my gym routine, but joining this gym almost two years ago has been one of the best decisions I've made for myself. Jennifer is an amazing trainer who truly pushes you to do your best, while making every class fun and enjoyable. Her energy and support have made a huge difference in my motivation and confidence.
When I started I felt very welcomed and supported. I now consider this my gym family. Even my kids love coming here and it is nice to see they are having fun and making friends while Mom gets a great workout in! I highly recommend Master Trainers to anyone looking for a supportive, motivating gym environment!

This gym has changed my life for the better.

I was struggling as a new mom. Not being able to have someone watch my child consistently so I can work out and trying to find a place to work out that I didn’t just have to drop off my child (mom guilt I tried and he cried the whole time).

I was offered a free class. Started the challenge. Fell behind for health reasons. Waited for the next challenge stuck with it the best I could and now I am signed up. Staying consistent is my goal. Already my mood has gotten so much better, the amount of energy I have has increased, and overall just grateful I found this place.

All the moms are amazing and kind. Best part the owner is a Mom and understands the struggle.

I tried out the 4 week promo for $75 and I was hooked. I've been with MTC for 7 months now. I have notice so many different changes and I was getting stronger. Jen and Dan are amazing trainers. They have helped me tremendously with my posture and pushing me to my limits. I highly recommend MTC!

I am so glad I found Master Trainer’s! Daniel and Jennifer have been nothing short of amazing with helping me transform physically as well as mentally. Most recently I lost 30lbs in 8 weeks during their biggest loser challenge for 2018. They have pushed me way out of my comfort zone and instilled confidence in me in a way I never imagined. Come try and see for yourself, 1st class is free! There is no comparison between MTC and other bootcamps. This place is a family atmosphere with great positive energy. Love MTC !!!

Jen and Dan were very welcoming when I was a newcomer and even now. They pushed me when needed and allowed me to make my own best judgement if I felt certain workouts or weights needed to be adjusted based on my body and needs. When I found out I was pregnant they modified workouts to benefit me and the baby. The workouts are challenging and I always leave in a better mood. Thanks for all you guys do!

Although there is many boot camp style gyms around, I am so glad I chose Master Trainers of CA. The trainers, Jennifer and Daniel are really down to earth and knowledgeable. Everyone is so welcoming and you don’t feel judged. I originally joined as part of a challenge, but since then have decided to become a permanent member. It does cost a little more than your traditional gym, but you’ll also push yourself to come and will actually enjoy it. What makes it worth it for me: my child is welcomed(at no additional cost), no waiting for machines, trainers correct your form, multiple sessions a day to fit anyone’s schedule, I feel more motivated, everyone is so encouraging and welcoming, trainers help troubleshoot your diet, classes aren’t too large so it feels like you have a personal training session everyday, last and most important, 45 minutes here is a better workout than when I spend 1.5 hours at regular gym. If you’re considering trying something new, definitely come check out this gym. You will not regret it!!

Jen & Daniel Jones make it priority to provide the best services to all members and truly care about your progress. With multiple classes a day and meal planning seminars, they make sure to set you up for success. The classes are challenging but so much fun!

Where do I even start . . . . . the trainers are husband and wife and make a great team . They push you to do better and better . Better than you thought you could do. Every workout is fun and challenging. Every day they explain them and make sure to show you easier ways to do them if you are having a hard time. There is a section where your kids can hang out and watch a movie or play. It's truthfully like a huge fitness family. If you have ever wanted to join a boot camp this is the one to join. You won't regret it.

Lots of fun and laughs and motivation overall.... being able to bring my son and have him in the kids cave while i workout is a huge deal breaker for me.... that was always an excuse for me and now i can be held accountable for not showing up.... no excuses.... fast, fun, and family!!!!

My journey started with a message to somebody I didn't know. It was a message asking for help. I had reached my rock bottom. Worried, scared and unsure I continued to message Jennifer explaining that I had issues associated with PTSD. My message was not only heard but was met with compassion, sincerity and most importantly she helped to create a place of comfort.

"Fitness will save your life." Words that have impacted my life far beyond my expectation. I was given a tour so I could visually see where I will be. I had issues with the unknown and small spaces.

My first few weeks were rough. I would have to stop due to anxiety from not being able to breathe. I would sometimes feel anxious from being around others I didn't know. Jennifer gave me that space, was patient knowing I would return. I did return. Every day after I left I felt a little better. Each day more than the last.

3 weeks passed and I was no longer having anxiety. I was now pushing harder, stronger determined to be a better me. Here I am roughly 17 weeks out and I am over 20 pounds lost! The inches just keep falling off! Master Trainers started the foundation that helped create a new me. I would not be where I am now if it wasn't for Jennifer and Daniel.

Private Facebook club to share the ups and downs of this journey. The countless messages of fears, feeling down and or questions. Jennifer answered every one. Messages filled with encouragement and motivation. That same attitude has rippled down to all of us. Constantly encouraging one another to reach whatever goal we may have. This is not just a place to go and work out. It's a place where family is. A place where a team is.

It's a place for you.

I knew very little about fitness, health, let alone what I actually wanted in my fitness goals. I don't like to write reviews unless my experience was fantastic! This was, the trainers are experienced, know what they're doing, answered every single question and provided to me personally. At first I was scared, this skinny guy with a a slightly extended belly seeking training.

The moment I shook hands with the owner all that melted away. Thanks Master Trainers of California! You guys were in constant communication, helped me feel better physically and mentally and now I am more motivated to get in shape, stay fit and eat healthier. They put the personal in personal training but with a professional touch. Thanks again!! Central Valley, Master Trainers says it all - check them out and maybe I'll see you there!
