    I lost 20 lbs in 3 month working with Eugene! Before working with him I struggled with confidence and didn't feel comfortable in my own body. He taught me everything I needed to know about my nutrition along with how my body would react to different workouts. Working with someone helps keep me motivated and on track. I highly recommend one by one fitness if you are looking for a new you in 2021.

    Post-training photo session! ;)

I came across Relentless Boxing, saw that the owner and coach, Arturo, is a former professional boxer, and that the gym actively trains and competes fighters. Everything looked solid, so I reached out to set up training sessions. Coach Arturo is an excellent teacher. He was patient with my learning process and beginner-level gaps, explained things clearly, and created a welcoming environment from the start. Each session was enjoyable and productive, and he gave me specific drills and exercises I could work on independently to improve my weaknesses. I told him footwork was my biggest area of concern, and he delivered exactly what I was looking for in both coaching and instruction. Don't feel intimidated by the fact that this is a real fighter's gym. If you're serious about learning proper boxing skills and technique, this is a great place to train. Come in with a positive mindset, be respectful and committed to learning, and Coach Arturo will genuinely help you progress toward your goals. 1000% recommend this gym for any level of boxing.

The coaches actually teach technique -- footwork, combinations, defense, conditioning -- and they push you to improve every class. The training is legit. You'll hit heavy bags, do partner drills, conditioning, and learn real striking fundamentals. Some people here compete, so the level can getg serious if you want it to. But beginners are still welcome and the coaches help you learn from the ground up. The environment is motivating and the workouts are tough. Expect to sweat a lot and be sore, but you'll get in shape fast and actually learn how to fight, not just "work out."

Once you've mastered the basics, their advanced classes provide the perfect environment to continue learning, growing, and testing your skills. What sets Smash apart from other gyms I've trained at is the strong sense of community. I met a lot of amazing people, both students and coaches, and the camaraderie there is unmatched. It wasn't until I moved away from the South Bay and trained at other gyms that I fully appreciated how special Smash is. While other gyms are good, they simply don't compare to the experience I had with Coach Rudi, Jose, Tristan, and the rest of the team. If I ever move back to the South Bay, or even just visit, I'll definitely drop by for a session.

It allowed me to get an extra hour of a workout in during the week and now I'm hooked! Krav is a real world self-defense that makes me feel strong and prepares me for real life situations. ASD also offers many other classes and so many talented instructors! Coach Shayne has been a big influence on myself and my husband. He continues to help us learn proper fighting techniques. Andrea is an awesome coach who continues to amaze us! Amit, Troy, Chris, Sergey, Marziya, and Jason have all taught me so much in Krav. Ilya's Hyrox and Fighter Flow classes are fun and a great workout! He also has a cook book that explains easy and healthy recipes! Manny's Boot Camp/kickboxing classes are always intense and will leave you sore. James' DEKA class was creative, hard and definitely worth a try! My son has enjoyed the Kids Krav classes....thank you James, Andrea, Anh and Marziya for teaching the big group of kids! I love watching him come home and practice and share what he learned. We often compare what we are all doing in class during the week. I can't forget Neal, the owner! And Carrie at the front desk! They always make us feel welcome and at home! I joined the Locked In For Summer Challenge that they organized at ASD. It has helped me stay focused on my nutrition and fitness goals. And has helped me meet some new friends! Overall, ASD is a super special place. I'm so glad my family found it and I'd recommend it to anyone interested!

What I really liked about this gym was the variety of classes they offer. You can try different types of workouts and figure out what you enjoy without having to commit right away. They also let you borrow gloves and other equipment for free during the trial classes, which I thought was a really nice touch. I ended up trying the HIIT and DEKA classes, which were my favorites, and most of the coaches I had were really great. Unfortunately, my experience with one of the kickboxing classes wasn't as good. I specifically asked multiple times beforehand if it was okay that I was a complete beginner, and I was told that it was totally fine. However, when I showed up, pretty much everyone else already knew what they were doing, so I naturally felt a little intimidated. I also wasn't given much guidance despite being a first-timer. What really bothered me was that the coach called me "silly" when I wasn't able to follow the instructions. I understand that a fast-paced class can be challenging for beginners, but I didn't think making fun of someone who was trying something for the first time was appropriate, and it definitely put a damper on the experience. One other thing I wish they had was a proper locker room or changing area. They have gender-neutral bathrooms, but they didn't feel clean or comfortable enough to change clothes in, especially if you're coming straight from work. I really liked the variety of classes and the generous trial period, and most of my experiences with the coaches were positive. I just wish the beginner experience was a little more welcoming and that they had a better space for changing.
