If you’re a regular in the gym, it’s likely that you know the benefits of packing as many compound exercises into your training as possible. Working multiple muscle groups and joints at once through moves like squats and burpees not only helps you carve out a lean physique, but also results in everyday strength benefits and better mobility.

So you won’t need any convincing to try this circuit from fitness studio F45 Kingston, which focuses on functional HIIT workouts. It’s aimed at people who are already training regularly and will take around 36 minutes to complete.

If you’re newer to the gym, here’s a more accessible functional workout from F45 Kingston.

How To Do The Workout

Tackle four rounds of the circuit below, working for 40 seconds on each of the nine exercises, with 20 seconds rest between moves. Your aim is to complete as many reps of the exercise as possible in each block of work.

Don’t slack off or you’re missing the entire point of HIIT (high-intensity, yeah?), and pay close attention to the Dos and Don’ts for each exercise provide by F45 Kingston’s coaches.
