Great studio, great trainers. I've taken a few classes with Bobbie Jo, Miles, and Jess. You get a different flavor of Rumble with each trainer which keeps it interesting.
I've had some issues with my credits showing up from time to time but the staff has always been helpful in trying to solve the problem. I've even had an open line with their biz ops EVP Louie, who was so incredibly helpful and answered my emails at all hours. Pretty rare to get support like that from a real human these days but I think it speaks to their staff, training and the entire business.
Highly recommend checking out this studio 👊

My friend and I both needed to reschedule our class because something unexpected came up. Ellie was so incredibly accommodating and returned our credits. We were able to rebook and had an energetic and challenging workout with Chris- Rumble's good workout studio with great staff and instructors!

My first boxing/boxercise gym that I settled down in—CHELSEAAA! The vibe is great, it’s clean, staff is friendly, bags are all good. Good spacing between you and other people boxing on the bags & the floor. I honestly toned down by going to 3–5 classes here, the effect for a year will definitely show even more😎. Honestly love this gym!
If you bring your own wrap & gloves you don’t need to pay first class. Similar to how in Pilates you need grip socks, here you need handwrap (they have it if u don’t), boxing gloves, and good energy! 🥊
