"This review is for the Kids Martial Arts and Smash and Bash Bootcamp held at Smash Gyms. I was referred to Smash Gyms by a family member who trains in the Brazilian Jiu Jitsu class at Smash Gyms. The atmosphere in the gym is very welcoming to all. My son, who is 9 years old, took a liking to the Kids Martial Arts class on the very first day. His confidence, discipline, and knowledge of self defense has rapidly developed since enrolling in this school. He insists that he wants to continue to train daily. The instructors leading the Kids Martial Arts program do an excellent job working with the children. Parents can work out during the kids' class as well. I have taken the Smash and Bash Bootcamp while my son is training. This also is an awesome, challenging, and very convenient class for any parent wanting a great workout while their child is training. The instruction, workouts and gym have been a positive experience. I would recommend that anyone who is interested begin by enrolling in the free week trials offered at Smash Gyms." - Alex R

"Amazing, organized, and fun kids classes. Focuses on kids fitness and technique. Great kettlebell class. The instructor is very experieced and detailed. They also have kickboxing, Krav Maga, jujitsu, Zumba, and bootcamp classes. I can't wait till I can find time to do them all." - M. Kelly

"Generally, I hate walking into gyms for the first time and having to "consult" with pushy sales people trying to get you to buy a membership at their gym before you try it out (ie. Fitness 19, Club One, 24 Hour Fitness). So it was nice to walk into Smash Gyms and not have them try to sell you on multiple types of plans. I was able to try different types of classes first using the Amazon Locals deal. After taking the kickboxing class, I was pretty much sold! The boot camp classes are also pretty awesome. I've been a member now for about a month and managed to lose 15 pounds!! Perks = no more dieting and watching my calories! As for how this compares with other kickboxing gyms, I've only tried one other kickboxing gym (Unlimited MMA in Milpitas). It was okay but I like the atmosphere here better--not as intimidating and the people are nicer. Also, this gym is closer to the freeways, makes it easier to hop on back to the 237 or 101 after working out. If you have any kids, there's a play room area and they also have martial arts classes for kids." - Mary N.

"Smash Gyms offers an excellent Brazilian Jiu Jitsu program with excellent and knowledgeable instructors. Furthermore, the atmosphere is very welcoming, and we learn not only from the instructors but also from each other, as everyone here is willing to help each other out. Definitely the best place to go!
- Thaibinh

Came here for a week trial of unlimited classes! Got to try out kickboxing which was very intense since I had only tried out cardio kickboxing classes before. The instructors were all super helpful anywhere from helping newcomers with the equipment to technique tips. " - Stacey L

"This place rocks! The atmosphere is very friendly and casual, not intimidating at all. People (staff and clients) are friendly and helpful. Walk in the door and Rudy will help you out on what you need to get you started.I tried out the circuit training at noon, kickboxing, and zumba. Circuit training is great workout, small class and personal attention. Zumba is only as good as the instructor, and Raquel is energetic and fun. Kickboxing is pads and mitts, not the kick in the air stuff, good workout, and the instructors walk around to make sure people's forms are correct. Though your workout quality do depend on a decent partner.The only complain I have of this place is no shower, other than that, it's perfect. ." - Viola C.
