From the reviews

Great Facility! Friendly Staff! Place is well organized and clean! Coaches are excellent!! We've been training here for a year now and my 13 year old son just loves it! He has learned so much in such a short time! Very proud of him and we just love this Gym! Old School style!

Sweet Science is a great place to train. I really appreciate their focus on teaching strong technique combined with fitness drills, all of which is fun. The trainers treat clients like individuals, which allows them to give instruction that help you grow as an athlete and fighter.

Your first BJJ class at Sweet Science Boxing & MMA

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.
