From the reviews

I've been working out at The Shop for 6 months & I've seen amazing results! At first, I was intimidated because I never exercised & I knew absolutely nothing about boxing. I thought I would be embarrassed working out & trying to box, but on the contrary, everyone is very professional & encouraging!

The Shop is the BEST KEPT SECRET in all of California. Coach Eric aka "The Head Chef" has been cooking up professional boxing technics for 2 decades. His approach to boxings greatest details is 2nd to none. Schedule a private training session and you won't be disappointed.

Trained in couple gyms and as a person that wants to make it a career. This is the place for me. I get pushed and coach Eric puts in the time to teach us boxing with conditioning. The price is really good for the amount of time he puts into us

Your first muay thai class at The Shop. Strength and Fitness

Nervous about walking into a muay thai 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 on pads and bags — not fighting. Rest whenever you need to; no one will bat an eye. What to wear: shorts or athletic wear and a t-shirt; you'll train barefoot on the mats. What to bring: water and hand wraps if you have them — many gyms lend gloves for a first class, so it's worth asking when you call. As you keep training you'll add your own gloves, wraps, a mouthguard, and shin guards. Sparring is optional and comes later, once your fundamentals 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.

Muay thai is a contact sport. Ease in, 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.
