EXCELLENT Based on 52 reviews Posted on Sophie CushingTrustindex verifies that the original source of the review is Google. Lots of accommodation !! Great workout. 🏋️♀️Posted on LaurenTrustindex verifies that the original source of the review is Google. I have been a member of Rumble Fitness for the past 6 months and I have thoroughly enjoyed my experience so far. They offer Tabata, Rumble Boxing, Spin and Bootcamp classes, all of which I have participated in. The classes are high energy and very engaging, and Isaiah and Victoria are encouraging and dedicated coaches. If you are looking for an incredibly supportive environment, which can accommodate all skill levels, fitness or experience, I highly recommend you choose Rumble Fitness.Posted on Andrea HarwoodTrustindex verifies that the original source of the review is Google. Victoria is the best instructor, my best friend took me for my first class and It was 10/10 she wasn’t hard on us for our first time and made us feel very comfortable the whole time and got very sweaty. Thank you Victoria!Posted on Isabella RimanTrustindex verifies that the original source of the review is Google. When I first started my fitness Journey I hadn’t worked out since college and had just lost a lot of weight. So naturally was feeling very nervous and intimidated to re join the fitness world. As soon as I walked into Rumble Fitness I was welcomed and made to feel so comfortable. Isaiah is a wonderful and motivating coach who meets people where they are at on their fitness journeys and helps guide them and push them to their goals! I have now been going to Rumble for a while now and have never felt and looked better, with the high intensity workouts my body is finally going back to what I always knew it could be again! My only regret is not going sooner! Thank you Isaiah for helping me re-gain my life and self confidence back! What an amazing Spin Class Rumble Fitness offers! Come give it a try. They welcome all individuals of all fitness levels, I'm very new to spin so it was nice having such an upbeat and fun class with built in fans to cool you down when you are working hard. To top it off at the end of class you get an ice cold eucalyptus towel to freshen up. Defiantly the best spin class in brockville.Posted on Debra TimofteTrustindex verifies that the original source of the review is Google. That was on heck of a spin class. Still feeling amazing from that spin class with an Amazing team. And an absolutely amazing spin instructor Victoria. Who guides and gives encouragement. Thank you so much.Posted on Bree DeButteTrustindex verifies that the original source of the review is Google. Spin at Rumble is the place to be! Victoria’s classes are upbeat, full of energy, and push you out of your comfort zone. Spin group fitness is motivating and will help you reach our goals. Rumble Ride is the best spin around!Posted on MaryanneTrustindex verifies that the original source of the review is Google. Amazing Monday morning Rumble Ride spin class.

I love Rumble Fitness with the variety of classes like Tabatta , Cardio boxing , Bootcamp and especially spin classes !!
