From the reviews

Black Belt America of Rutherford is such an amazing place & experience! My child has been here for 4 years and has come out of her shell. She has built discipline, and physical strength through regular training and it is showing.

★★★★★ — Isa, Mar 2026

My son trained with Mr Jaworski for many years. We were sad when he resigned from our home Academy. He was my son's favourite instructor at the Academy I didn't realize this until he won a competition and was able to chose a free private lesson with an instructor of his choice. My son chose Mr Jaworski.

★★★★★ — Rachel, May 2023

Mr & Mrs Jaworski are an incredible martial arts team. I worked closely with them for a few years when I was in high school as a martial arts instructor and kickboxing instructor. Mr Jaworski is one of the most patient people I have met and truly cares about each of his students’ progress.

★★★★★ — Devika, Sep 2022

I've been taking kickboxing classes here and I can't recommend it enough! The instructor, Christina, is truly fantastic—so knowledgeable, patient, and motivating. Every class is challenging and fun, which keeps you wanting to push yourself.

Your first kickboxing class at Black Belt America of Rutherford

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.
