From the reviews

I recently moved here from Boston and was looking for a workout routine and to try something new and got a one week trial pass to Smash Gyms and decided to give it a shot. Definitely the BEST decision I've made since moving here. The people who work at Smash are really friendly and welcoming.

★★★★★ — Jessica, Nov 2012

I've been going to this gym for about two years. I have enjoyed every bit of it! The staff is incredibly friendly and helpful. It doesn't matter if you're a beginner or experienced person, this place caters to every level. And if you're a beginner, don't be afraid to try it out.

★★★★★ — Eddie, Oct 2013

Out son (age 9) has been coming for 3 months to learn Jiu-Jitsu and I cannot say enough about how happy we are with Smash Gyms. The instructors are all very patient and thoughtful, particularly with the less experienced kids and make sure everyone gets the most out of the lesson.

★★★★★ — Gavin, Feb 2015

I've trained in various systems, so I feel like I have a good idea as to what I'm looking for in teachers and schools. When I moved to Sunnyvale, I was simply looking for a gym where I could train and maintain. At Smash, I was very pleasantly surprised.

New to kickboxing? Start at Smash Gyms Sunnyvale

Smash Gyms Sunnyvale comes up as a beginner-friendly gym — noted on their own site. If you've never thrown a punch or a kick, that's exactly who a good beginners class is for. A few things worth knowing before your first week. First, you don't need to be fit or coordinated to start — you get in shape by training, not before it, and coaches scale every drill to you. Second, you won't be thrown into hard sparring — reputable gyms build the basics (stance, footwork, and punches and kicks on pads and bags) first, and any contact eases in gradually under a coach's control. Third, all fitness levels really are welcome — ask about a dedicated beginners or fundamentals class time so your first session is alongside others who are also starting out. Most gyms are happy to let you watch or try a class first, so reach out before you commit.

Your first kickboxing class at Smash Gyms Sunnyvale

Nervous about walking into a kickboxing gym for the first time? Almost everyone is, and good coaches expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling the basics — stance, footwork, and punches and kicks on pads or a heavy bag — not hard sparring. Go at your own pace and rest whenever you need to; no one will bat an eye. What to wear: comfortable athletic clothes you can move and sweat in, and supportive trainers. What to bring: water, and hand wraps and gloves if you have them — many gyms lend loaner gloves for a first class, so it's worth asking when you call. As you keep training you'll add your own gloves and wraps (and shin guards once you start sparring). Sparring is optional and eases in gradually, once your basics are solid. Arrive 10–15 minutes early to sign a waiver and meet the coach. It gets easier fast — most people feel far more at home by their third class.

Kickboxing is a contact sport. Warm up, pace yourself, listen to your coaches, and if you have any injuries or health concerns, mention them before class and check with a doctor if you're unsure.
