From the reviews

The subscription was my BD gift, and I've been going to GenX for about two months by now. - I love the classes and coach Gen. He's super passionate about his training and entirely focuses on his students during the class. He's completely engaged during the training and gives constructive feedback to us.

★★★★★ — Sarah, Aug 2022

My daughters have been attending the Senshido class for nearly two years. Coach Gen is patient with the kids and offers a supportive environment. He gives the students time to acclimate but also provides structure while getting progressively challenging as they show improvement.

★★★★★ — Jamila, Oct 2023

A friend introduced this gym to a couple years ago through classpass. The routine fit my goals and I like the people in my classes so ended up becoming a member. Going to classes consistently put me in my best shape and improved my energy level.

★★★★★ — Mark, Feb 2026

My daughter has definitely benefited from the Gen-X Fitness kid's Senshido class. She has been working with coach Gen for over 6 years now. The combination of Muy Thai and Aikido (on alternate days) keeps class fresh and her motivated and excited.

New to kickboxing? Start at GenX Fitness

GenX Fitness comes up as a beginner-friendly gym, going by their listing and members’ reviews. If you've never thrown a punch or a kick, that's exactly who a good beginners class is for. A few things worth knowing before your first week. First, you don't need to be fit or coordinated to start — you get in shape by training, not before it, and coaches scale every drill to you. Second, you won't be thrown into hard sparring — reputable gyms build the basics (stance, footwork, and punches and kicks on pads and bags) first, and any contact eases in gradually under a coach's control. Third, all fitness 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. Most gyms are happy to let you watch or try a class first, so reach out before you commit.

Your first kickboxing class at GenX Fitness

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.
