40min
The class that built Rumble. A 40-minute, music-driven HIIT circuit that changes every single day, combining resistance training, cardiovascular conditioning and functional strength work. Our screens provide exercise demonstrations, while our coaches are on the floor to help your form, push you harder and keep the energy flowing.
Circuits start every 10 minutes throughout the day, which means there is no fixed class time and no such thing as being late. Walk in and a coach will get you going within 10 minutes: follow our structured warm-up, then jump on the next rotation. At peak times, such as before work, at lunchtime and after work, booking your start in advance is the better option.
Each day targets a different training focus:
A complete 40-minute session covering mobility, resistance, cardio and conditioning. The “Build” days emphasise developing muscular strength; the “Burn” days emphasise developing muscular endurance. Within short, intense intervals, you can expect compound movements, weights, functional equipment, bodyweight exercises.
Bring gym clothes and trainers. Everything else is provided. The last circuit of the day starts at 8:20pm Monday to Thursday, 7:20pm on Fridays and 3:20pm at weekends.
Open to all levels.
A very efficient workout, loved the exercises and the trainers were on point in correcting form and encouragement. Beautifully laid out gym and great music and since a circuit loop starts every 10mins you can jump in whenever you’re ready - just genius. Absolutely nailed it as a great work out!!
I really enjoyed the class—it was amazing! I felt every last burn, and the workout was both challenging and rewarding. The instructor was fantastic, and the atmosphere was great. I’ll definitely be coming back.
Great workout, welcoming instructors who motivate you and correct your form. Appreciate how the environment allows you to go at your own pace while providing enough structure. Will be back!
A great experience, the class was challenging but in the right way, lots of fun. Instructor was amazing & always made sure I was in the correct form! Would definitely recommend
