    Rumble Training

    Thank you Bradley for an amazing class! This man has so much energy, it’s palpable. He was *literally* bouncing off the walls (you’ll see). I love the HYPE that the Rumble instructor bring to the classes (both boxing and training), which makes it so much fun. Working out doesn’t have to be so serious! Not only is rumble training a great workout, but the amenities are fabulous. They even offer clean towels inside the studio in case your towel gets extra sweaty. The locker rooms are immaculate. I obliviously can’t say enough about Rumble!

    Rumble Boxing

    Fun, tough workout. I was expecting it to be Barry’s or fhitting room hard. It felt probably comparable to a fair fhitting room workout and a light to medium Barry’s workout. For sure what you put in is what you get out. Clear instructions, motivating instructor. Wish it were an hour long at 15-16 credits.

    Truly amazed today by the dedication of the Switch staff. Their jobs are hard enough, demo’ing at each station, but now they are disinfecting everything in between sets. I am doing my best to maintain social distance, and to contribute everyone remaining healthy, but I will seriously go crazy if I also don’t work out! Just wanted to let you know how much your efforts are appreciated. Thank you!! ????

    Amazing. Good for all running levels. You will push your speed and incline endurance levels to their limits, without ever feeling overwhelmed, get a quick toning kettlebell session in, and wonder where the time went / how soon you can do it again! Great deal / full body workout for minimal credits, especially if you are willing to workout late-ish.

    Body Camp: SWEAT

    So the reviews are true, Christine is actually really cool and welcoming. She takes the time to talk to you, remembers your name, asks you about injuries 1:1. She does go around during the circuit correcting form so you don’t hurt yourself. The only thing I don’t like is the warmup because you have to line up with others to do it and it’s not necessarily smooth, like you’re forced to keep up which isn’t a good feeling right off the bat to start or you’re waiting for the person in front of you. Also, since the space is small and because you’re zig zagging back and forth between stations, there’s a lot of times you almost bump into someone or vice versa. That said, it’s a tough, challenging workout and the instructor is really great so I’d still highly recommend it and plan on going back.
