From the reviews

This is a fun and supportive place to train where the instructors make everyone feel welcome. Miss Sarah has an amazing teaching style using humor and encouragement and managing to make success possible for anyone even if you don’t bring any experience.

★★★★★ — Tracy, Mar 2021

My fiancé and I just started a membership three weeks ago and we are hooked! The staff is so sweet and know what they’re doing. It is really easy to ask questions and get clear answers. Classes are later at night so we are able to work, have dinner and still go to class after.

★★★★★ — Kristi, Mar 2021

My youngest daughter said that she really likes the school because they help develop skills by building up to them. Starting small and building. The instructors make the classes and the experience fun and enjoyable while still being focused on discipline and holding the kids accountable.

★★★★☆ — Edward, Mar 2021

Both of my young children take classes here, one says, “he loves kicking the wave master” and the other says she loves that she can do so much more than karate like, “birthday parties, parent night out, day camp and more.” They both have grown socially and physically.

★★★★★ — Sara, Mar 2021

Your first kickboxing class at America's Best Defense - Shrewsbury

Nervous about walking into a kickboxing 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 — stance, footwork, and punches and kicks on pads or a heavy bag — not hard sparring. Go at your own pace and rest whenever you need to; no one will bat an eye. What to wear: comfortable athletic clothes you can move and sweat in, and supportive trainers. What to bring: water, and hand wraps and gloves if you have them — many gyms lend loaner gloves for a first class, so it's worth asking when you call. As you keep training you'll add your own gloves and wraps (and shin guards once you start sparring). Sparring is optional and eases in gradually, once your basics 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.

Kickboxing is a contact sport. Warm up, pace yourself, 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.
