From the reviews

I found Training Grounds when looking for BJJ-MMA for my son, who needed to build his physical self confidence and learn how to defend himself. I met with Coach Pete and immediately connected with him through his experience and understanding. My son has been training at TG for a couple of months now and loves it.

★★★★★ — Liana, Dec 2022

Our five-year old daughter has been attending Training Grounds’ Ninja class for three months now. She was not exposed to Martial Arts prior to the class and yet she began enjoying the jiu jitsu routines immediately.

★★★★★ — Allison, Jul 2024

TG (Training grounds) is such a great place for my child. I wasn’t sure he would take to it coming from Taekwondo. Although, from day 1 he was hooked and I credit that to TG.

★★★★★ — Brian, Dec 2024

We have recently signed up for Training Grounds MMA about 3 months ago. From the sign up experience to the whole training classes thus far everything has been great. The trainers Professor Wil and Peter have always been extremely great to deal with AND very technical and great trainers.

Your first muay thai class at Training Grounds Jiu-Jitsu & MMA

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.
