From the reviews

9Round is an incredibly welcoming and supportive community where I’ve truly found a sense of belonging. I discovered 9Round while searching for something low-pressure to get me out of the house, help me focus on my fitness goals, and give me space to do something just for me.

★★★★★ — Victoria, Jun 2025

If you’re looking to try a new gym or switch up your workout routine, I cannot recommend 9Round in San Leandro enough. I never considered myself an avid gym-goer because I was always afraid of using equipment wrong or looking silly doing an exercise.

★★★★★ — Kayleigh, Nov 2025

9Round offers an incredibly efficient 30-minute full body workout across 9 stations, each guided by onscreen demos which I truly appreciate. The workouts are fun, challenging, and changes every day. Morning sessions are a definite highlight because of the amazing owners, Ceez and Ray!

★★★★★ — Diana, Apr 2025

If you’re thinking about boxing and don’t know where to start, 9 rounds is the perfect gym for you. You’ll get your heart racing and blood pumping. Everyone is so nice and welcoming. I was a little nervous to start but Ray the instructor is very patient when it comes to showing different movements.

New to kickboxing? Start at 9Round Kickboxing Fitness

9Round Kickboxing Fitness comes up as a beginner-friendly gym — noted on their own site. 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 9Round Kickboxing 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.
