Optimise Your Fitness: Why Rumble's Split Workouts Work

Split workouts at Rumble mix Build days for strength and Burn days for endurance on the Re.HIIT circuit. Here’s the week and how to use it.

Every day on our Re.HIIT circuit has its own focus. Build days emphasise developing muscular strength, and Burn days emphasise developing muscular endurance. Each day also has a body focus, and the programme is new every day, so you know what kind of session you’re walking into while the workout itself stays fresh. Below is how the week runs, and how to fit it around your goals.

Your week at Rumble

The weekly focus, day by day:

Whatever the day, the format stays the same. Each circuit is 40 minutes plus a warm-up, a new one starts every 10 minutes, and it runs at both our studios, in Dalston and Fitzrovia. The screens demonstrate every exercise and a trainer on the floor adapts each station to you, so the circuit is open to all levels. The last circuit starts at 8:20pm on weekdays (7:20pm on Fridays) and 3:20pm at weekends.

Why the split works

• A clear focus each day: you know before you arrive whether it’s a Build or a Burn day and which part of the body it centres on, so you can plan your week around it.
• Variety built in: the programme changes every day, so even the two upper-focus Build days are different workouts.
• Pick the days that suit your goals: if strength is your priority, two Build days a week is a simple place to start, and our guide to strength training for women in London has more on getting started.
• Combine Build and Burn: add a Burn day when you’re ready and your week covers endurance as well as strength.

As of October 2026, the Discover offer (new clients only) is three classes for £45, used within a month at either studio: enough to try a Build day, a Burn day and one more of your choice.
