A gym chain has expanded its offer with a range of new carbon neutral workouts.

Boutique fitness and wellness studio, Rumble, will expand its HIIT circuit offering, from its flagship Dalston location, launching Rumble Circuit. The new zero-carbon footprint studios will open in three new London locations, including Primrose, Fitzrovia and Shoreditch.

The expansion of Rumble’s unique futuristic HIIT circuit offering will allow members to train with both built-in screens hanging from the walls, showcasing the exercises to guide them through their workout, and trainers, to motivate, supervise, push and assist.

Founded by Ukrainian, Lenka Chubuklieva, Rumble will be supporting We Help Ukrainians via the studios, to help Ukrainian refugees find support worldwide and is personally assisting at We Help Ukrainians’ London warehouse for support and aid.

All new studios will consist of one room with four separate stations and over 600 exercises every 10 minutes. The HIIT circuit classes will last 40 minutes, with members moving from station to station every 10 minutes, and new classes joining after every 10 minute rotation.

Whether you’re running late or arriving early, this won’t matter with Rumble Circuit as you can drop into the next rotating class, making it the most flexible HIIT circuit workout in the UK, following Rumble’s mantra of It’s never too early or never too late to HIIT the gym.

As with Rumble’s flagship Dalston studio, Rumble Circuit will continue its environmental efforts and plant a tree for every workout to help offset its carbon footprint. All products in the studios will be sustainably sourced, with no single-use plastic on site, making it a studio with a conscience. Rumble has partnered with brands like Avobar, which provide healthy, sustainably sourced delicious food, and Cowshed, which provide environmentally-friendly handwash, shampoo and conditioner.
