Absolutely recommend workouts! Small gym with big results. It’s like having a personal trainer. Reasonable prices. Choose from different packages or just drop in. My first three sessions were $10 each. Check the website for this great offer.

I've been training here for about 1 year now, in the group class training.

If you are willing to put in the time and consistency it takes to see results (3-4 days a week), you will see results. Gustavo is genuine, and cares for everyone he encounters. He knows when I'm capable of doing more, and I've reached all my record weights lifting here. I never feel pressured but encouraged.

I pay for training because it holds me accountable to show up when I make an appointment, and it's a space where the equipment is available without waiting for it at a regular gym. The space is always clean. You won't regret it!

I've been working out with Gustavo at Gonz9 for about 5 months now. Before that, I haven't had a serious workout in about 5 years, due to the pandemic and having kids.

Gustavo's classes are perfectly sized so they feel like a personal training session, but open to people of all various fitness levels. Not only does he tailor each workout for the individuals abilities, but they are scalable so you see your progress over time. Not only have I seen my strength return to levels where it was before kids, but I don't get winded running to catch my BART anymore!

I could not recommend Gustavo and Gonz9 enough for those looking to get back into it or improve their overall fitness!

I’ve been working out with G for a couple months now. All I can say is he is definitely great at what he does. Very knowledgeable and an all around great guy. I’ve been with a lot of trainers who don’t listen but G listens and helps you focus on what you need for your body. I highly recommend!

We've been going to Gonz9 for about a month and it's been great! We signed up for 2-1 personal training to give both me and my husband some majorly needed motivation and it's been just what we wanted. Gustavo has been great, coming up with personalized sessions for help each of us individually reach our goals. He pushes us enough that every session we are feeling it but also motivated to go further the next time. Highly recommend!

⭐️⭐️⭐️⭐️⭐️
Gonz9 Training is one of the best gyms I have been to for strength and conditioning classes. Gustavo is incredibly knowledgeable and strikes the perfect balance between pushing you to achieve your goals and encouraging you to listen to your body.

The classes are challenging without being intimidating. The exercises are varied enough to keep things interesting and fun, but there’s also enough repetition to track your progress and feel your improvement over time.

Highly recommend!

Never had a personal trainer but ever since I started I wish I would’ve started sooner it’s much easier having a 1 on 1 session rather than thinking I know what I’m doing. Was 270 when I started and writhing 3 months I lost 30 pounds, granted I could’ve lost more but that was on me and my eating habits. Gustavo truly is a great trainer and would recommend to any and all who are ever considering it!

Just started going with Gustavo, clean gym, very easy going, and will work with your needs or any health issues you may have. I struggle with having correct form while lifting, and Gustavo has been quick to correct my form to prevent any potential injuries. I'm looking forward to seeing the improvement I'll have in my fitness journey during these upcoming months with Gustavo

Gustavo provides a clean and comfortable environment where I can ask questions and express myself. His training style has helped me identify my strengths and weaknesses.. I’ve been needing a challenge and this is it! Walking out the door I feel accomplished and stronger both physically and mentally.

Working with Gustavo has been a refreshing experience after so long of following my own routine at the gym. I will definitely keep coming back for more strength. 💪🏼

Reflections on Three Years of Growth

As I sit down to reflect on the past three years of training under your guidance, I am filled with gratitude for the journey we've embarked on together. From the moment I walked into your gym, I knew I was in good hands, but I could have never anticipated the profound impact you would have on both my athletic abilities and my personal growth.

Your unwavering dedication to my development as an athlete has been nothing short of inspiring. You've pushed me beyond my perceived limits, encouraged me to strive for excellence, and believed in me even when I doubted myself. Thanks to your expertise and support, I've achieved milestones I once thought were out of reach.

But it's not just my physical strength that has flourished under your guidance – it's also my mental resilience and self-belief. Through the highs and lows of training, you've taught me the importance of perseverance, discipline, and self-care. You've helped me cultivate a mindset of determination and positivity that extends far beyond the gym walls.

Beyond the sets and reps, you've been a mentor, a motivator, and a friend. Your passion for what you do is contagious, and it's impossible not to feel inspired in your presence. Thank you for believing in me, for challenging me, and for helping me become the best version of myself, both as an athlete and as a person.

As I look forward to the next chapter of my journey, I do so with confidence, knowing that I have you in my corner. Here's to many more years of growth, achievement, and friendship. Thank you for everything.

If you’re in need of a personal trainer in the East Bay, look no further! I have never felt so comfortable and confident with a trainer than I have with Gustavo. He listens to what you want, works with your skill level (or complete lack, if you’re a total beginner like I was), and creates a safe and welcoming environment. As a college-aged woman who’s been training with Gustavo since I was eighteen, he has only ever uplifted and encouraged me on my lifelong journey towards a healthy and sustainable lifestyle. He gives you the tools and knowledge necessary to protect and uplift your health and wellbeing, and I can’t recommend training with him enough!

I am an undefeated professional boxer through 12 fights that’s been training strength and conditioning with Gustavo for 5 years. His attention to detail has made my job exponentially easier. His facility is always clean and he is always early for my sessions. Those things mixed with his professionalism makes it an inviting environment that I enjoy going to a few times a week. If you are a professional athlete like myself trying to get to the next level or just an everyday person trying to work on their fitness and maybe shed a couple pounds I would highly recommend Gustavo.

Gustavo’s the type of trainer that helps you build your confidence which motivates you and keeps you focused on your overall goals. When I train with him, I’m constantly feeling challenged and that’s what keeps me going.

If you’re anything like me and feel intimidated and overwhelmed on how to start your fitness journey, start with Gustavo!

He’s an amazing trainer and is incredibly knowledgeable. He caters the workouts to your fitness goals and needs. Beforehand I would do random workouts and never see results but now with his personalized workout plans it takes the guessing out of everything so all I need to do is just show up. Each session I leave feeling stronger and more confident than my last and I know I got a really good workout in! When I first started he understood that there was a learning curve and was really patient in showing/explaining the exercises, making adjustments if needed, correcting my form, etc. all while making sure I’m being safe (to avoid injuries).

I used to think that a personal trainer was out of my price range but Gustavo has cost friendly packages and offers group classes so you’ll definitely be able to find something that works for you. He also has a wide variety of availability so if you’re an early bird or a night owl, he can do it.

With my 1:1 sessions I love that I’m able to have the gym to myself, don’t have to wait for a machine to open up, he always has good music playing, I can ask him questions about the exercises and nutrition, I don’t feel embarrassed if I’m doing an exercise wrong, he’s really encouraging and helps me push myself, and I don’t feel judged.

He’s definitely helped me reach my fitness goals and continues to help me reach my next goal! He keeps things fun, fresh, and doesn’t feel boring or redundant at all. Totally worth the investment in him and yourself!

Best decision I made in 2023!!

I was turning 30 in 2023 and at the time I wasn’t content with my weight and overall health. It was May, so I finally decided to go all in on my health - but I knew I couldn’t do it alone. I needed help. And I came across Gustavo aka gonz9training
Best decision I made that year to train with Gustavo!!!!
Not only is he very knowledgeable, but his schedule is also very open and flexible - something I needed with my busy lifestyle.
As a female, I feel entirely comfortable and safe.

And its been about a year now and I have seen tremendous progress. Not only have I lost weight and inches, but I have gained so much strength. I came in not being able to do 1 ‘real’ push-up, now I can do multiple sets of many. With my squats and at the bench press, I started light with 25s and 15s. Now I squat 45s+ and bench press 25s. Every week I am challenged, and the accountability with personal training has been the biggest game changed for me. Had I not gotten Gustavo to train me, I wouldn’t have been consistent on my own!!!!

Have been doing 1 on 2 training with Gustavo, and it has been AWESOME! Haven’t worked out in years, and Gustavo really works with us, has patience and is teaching us proper way of doing things, it has been great and I am really looking forward to the rest of the sessions we have left and purchasing additional sessions. It’s great because the way he does it holds me accountable to show up, and put in the work!! And the studio, is really clean and well maintained, definitely recommend!!

If you’re in need of a personal trainer in the East Bay, Gonz9 Training is your place! Their personal trainer and owner, Gustavo, does everything and more to help and assist you on your personal fitness goals. I recommend going to him because Gustavo takes away the stress of figuring out what exercises to do, how many reps/sets you have to hit, and the annoyance of having to wait for a machine at the gym. He also has extra things like hair ties if you forgot yours, cubbies for your personal belongings, Gatorade for those electrolytes, and great music! I can wholeheartedly say I’ve seen improvements in my strength and stamina since I started training with him.
