From the reviews

Joining BJJ lifestyle Academy was one of the greatest decisions I've made. I grew up doing various martial arts and all of those felt very watered down to me. When I started becoming interested in BJJ I did my research and looked around. I tried a few schools out and this one felt like the real deal.

★★★★★ — Kody, Apr 2022

I've been attending coach Mikes academy for over a year now. The leadership is amazing, training will push your limits, and there are time slots accommodating nearly everyone. The friendship bonds you will gain thru Lifestyle BJJ will last a lifetime. Highly recommend giving it a try.

★★★★★ — James, May 2023

My experience at BJJ Lifestyle Academy has been great. I used to train at a gym 5 minutes from my house, and now I drive an hour one way to train with Mike, and the other great students there. I knew after my first class that this was the gym for me. I've been there ever since, two years and counting.

★★★★★ — Bart, Nov 2016

I started with Coach Mike and his team back in 2014 one year before joining the Army. Since then I’ve trained off and on all over the country and even in Europe. I’ve since been able to come in for drop-in sessions while visiting home.

New to BJJ? Start at BJJ Lifestyle Academy

BJJ Lifestyle Academy comes up as a beginner-friendly gym — noted on their own site. If you've never rolled or set foot on a mat, that's exactly who a good beginners program is for. A few things worth knowing before your first week. First, you don't need to be fit or flexible to start — you get in shape by training, not before it, and coaches scale the intensity to you. Second, you won't be thrown into hard rolling — reputable gyms build fundamentals (positions, escapes, and basic submissions) for weeks, live rolling eases in gradually, and tapping early keeps every roll safe. Third, all 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, and leave your ego at the door. Most gyms are happy to let you watch or try a class first, so reach out before you commit.

Your first BJJ class at BJJ Lifestyle Academy

Nervous about walking into a BJJ 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 basic positions and escapes with a partner — not hard sparring. Rest whenever you need to; no one will bat an eye. What to wear: athletic wear you can move in (or a gi if you have one); you'll train barefoot on the mats. What to bring: water and a mouthguard if you have one — many gyms lend a loaner gi for a first class, so it's worth asking when you call. As you keep training you'll add your own gi (or a rashguard and shorts for no-gi) and a mouthguard. Live rolling eases in gradually, 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.

BJJ is a contact sport. Ease in, tap early and often, 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.
