From the reviews

Looking for a great place to call home, this is your spot. Boxing and Muay Thai classes are excellent! My daughter has been coming here for over two years, she loves it and her progress has been amazing! I highly recommend Alex's personal training, it really makes a diferent when you get training tailored. 🔥🔥🔥🔥🔥

★★★★★ — Fabiola, Dec 2021

After having trained with Alex for two years, I can honestly say he is the best Personal Trainer in the Inland Empire area. Having begun training at 75 years of age, I find that now, at 77 years of age, I am stronger, fitter, faster.

Pain Cave I’ve seen champion belts come out of there, they work fantastic with kids, turning them into disciplined adults! Pain cave assesses your emotional and mental strength as well, to reach limits, then break you, rebuild you!

★★★★★ — Ross, May 2026

I’ve been training here for over 2 years now and honestly couldn’t ask for a better gym. Coach is always on point and pushes everyone to be their best. Highly recommend for anyone looking to get into Muay Thai or boxing.

Your first muay thai class at Pain Cave boxing

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. 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.
