You'll catch on easy of which instructors genuinely care about your growth. However, in-terms of experience & background - every instructor is absolutely legit. And I do believe it's the best gym around. During open gym hours - gym is closed 60-70% of the time which is incredibly frustrating since some people want to put in that extra work to really get better; plus paying them $180/month so I try to maximize my use of the gym itself. Not sure if it's a staffing issue but I probably have been turned away 50+ times thus far, quite frankly, it sucks. Can't have open gym hours if you're not open. Hopefully they improve at the new facility.

From day one, they made me feel welcomed, encouraged, and capable--no matter my fitness level. The coaching is top-notch: they pay attention, help with form, push you when you need it, and support you when you don't think you can keep going. The community is just as amazing. Everyone is supportive, motivating, and genuinely happy to see you succeed. This isn't just a CrossFit gym--it's a place that helps you build confidence, discipline, and a better version of yourself 100%. If you're on the fence, stop thinking and just show up. It worked for me, and it can work for you too

Everything I said in my previous review still stands, I just want to highlight how awesome the…read moretrainers have been during the last year plus as we've all had to negotiate the COVID pandemic. They've adapted to teaching a mix of in-person and online classes and they've done an excellent job of making things challenging while keeping workouts accessible and adaptable as needed for everyone's personal situation. All of the trainers here are excellent, but most of the classes I take are with Deanna. Training with her is an incredibly positive experience--she is completely committed to helping her clients succeed, and not just in the gym. And on those days when my tank is empty or I'm not with it for whatever reason she's completely understanding and is able to adjust things to meet me where I'm at so I still get a good workout in. A lot of it may be behind the scenes, but she works just as hard as her clients at helping them achieves their goals. Phoenix Gym is an incredibly positive, supportive, and judgement-free zone, and being a member here has been a life-changing experience.

Bootcamp has it's own deal. I came here for a free trial bootcamp class (and I'm hooked and coming back on Friday). Luckily it was 6 ladies and myself. I really liked that it was small and everyone was friendly. It started with some jumprope, followed by push ups (and repeat 5 times). Then we got our hands wrapped and put on the boxing gloves! We hit punching bags. Pretty fun to feel like Muhammed Ali. :) my knuckles are red. Boxing is only on Wednesdays. Then we did squats in between the different types of boxing moves. Then we got out some yoga mats and did different types of crunches. Sadly I forgot where my abs once were :( but I'm hoping to find them soon. Anyway, tons of fun!

I've trained at quite a few Muay Thai gyms over the years. Like a lot of people who move around,…read moreI've bounced from city to city and tried different spots. Most of them were solid. Good people, good workouts. But Jay's Training Grounds was the first place where things actually clicked for me. What stood out immediately was the way Coach Jay teaches. Instead of just drilling combinations, he breaks down the fundamentals and the reason behind every movement. Footwork, balance, timing, defense, how punches connect with kicks, when to check, when to counter. You start to understand the system instead of just memorizing techniques. That made a huge difference in how fast I improved. The atmosphere is also very genuine. No ego, no intimidation. Just people who want to train hard and get better. Beginners get clear guidance, and more experienced fighters still get technical details that sharpen their game. It feels like an authentic Muay Thai training environment, not a cardio kickboxing class. If you're in the Bay Area and looking for a place to train seriously while still feeling welcome, Jay's Training Grounds is worth checking out. Drop in for a class, talk to the coaches, and see it for yourself. You'll know pretty quickly why so many people stick around.

My Muay Thai journey started back in 2014, and from 2014-2018 I was fully committed to training…read moreuntil life hit me with school, work, and relationships that forced me to step away. During that time, I gained a lot of weight and felt like I lost a big part of myself. When I tried to come back, I found that the gym where I originally started had closed due to rising rent costs. I checked out a few gyms in Oakland, but none of them had that same community vibe where people truly enjoyed Muay Thai for the art and what it represents, I didn't feel welcomed Honestly, I felt lost and thought I'd never find that feeling again. I even considered driving far just to train because I missed Muay Thai so much. That all changed when I came across Coach Jay's bio and saw that he had trained under the same coaches I had when I first started. I looked at the photos, saw the location, and instantly felt the same vibe I'd been searching for. From day one, Coach Jay was welcoming, helped me get my technique back, and I immediately felt the support from the entire team. Since rejoining, I've gone from 260lbs to 210lbs, building muscle along the way thanks to the strength and conditioning classes (something I never had access to before). On top of that, I've been training in boxing, improving and learning a lot, while of course continuing with Muay Thai. I've even competed in a PKB and plan to keep competing in the near future. For me, Muay Thai and boxing here have not only helped me get in shape but also pushed me to grow mentally, physically, and spiritually. The training is tough but motivating, and the team always makes you feel supported like family. Everyone trains hard, but there's also real camaraderie and respect. This gym has given me opportunities to challenge myself in ways I never imagined, from sharpening my technique to stepping into the ring. It's more than just a gym, it's a community that keeps you accountable and pushes you to become the best version of yourself. I'm incredibly grateful to Coach Jay and the gym for helping me return to what I love and for improving my health. If you're serious about training or even just curious to try something new, I can't recommend Jay's Training Grounds enough. - Manny

The adult professional instructors are really engaged and invested in the growth of the kids. The focus on discipline is fantastic; the motivation to add bars to their belt (or eventually the next belt) really gets them going. And they're clearly just having more fun than gymnastics. We were just at an event there, and noticed afterwards how happy all the kids seemed (not just ours). There's a real positive energy.
