From the reviews

ABSOLUTELY AMAZING!!!! What an experience; what a workout! Best environment, best prices, best coach! I read numerous reviews before signing up & saw that people kept raving about how awesome "Coach Wendy" was.

★★★★★ — Gee, Mar 2023

I love these classes, I love the people, I love the instructors. I love fierce fitness. After 2.5 years I am still challenged every time I walk through the door. I am a much happier person when I work out on a regular basis and when I leave this studio I feel like gold. Prices are awesome for twice a week.

★★★★★ — Lauren, Feb 2017

I absolutely LOVE this place!!! ...for so many reasons. I joined Fierce Fitness about 2 & 1/2 months ago looking for a way to get back into shape. When I came to a free trial day at the new Tigard location, I was greeted by Brittany and Candice’s smiling faces. They were both so friendly, and weren’t pushy at all.

★★★★★ — Amber, Mar 2018

I had done kickboxing classes in the past and when I moved to Portland I had a hard time finding a class that I liked, until I found Fierce Fitness. It is one of the best workouts hands down! The two instructors are amazing and very informative and helpful.

New to kickboxing? Start at Fierce Fitness Kickboxing

Fierce Fitness Kickboxing 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 Fierce Fitness Kickboxing

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.
