From the reviews

There is no place quite like Sal Bartolo's boxing club. Boxing is in Sal's blood. He is a second generation world class boxer and a very experienced martial artist, teaching Muay Thai as well as sharing his expansive knowledge in boxing.

★★★★★ — S, Jul 2020

Sal is awesome and will guide you to be more disciplined and care for the details in technique. Will definitely get your boxer skills to the next level and 100% make you lose weight if that’s your goal. Sal is the best

★★★★★ — Christian, Mar 2022

I can’t recommend Bartolo’s Boxing Club enough. The instruction here is top tier. You get a full 2 hour session, which gives you real time to learn and actually develop your skills instead of just going through the motions. What really sets this place apart is the focus on technique and effective combinations.

If you want discipline and a tough, regimented experience, from a tough older guy with a heart of gold? Go there!!!

Your first muay thai class at Bartolo's Boxing Club

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.
