There are many ways to approach the gym. You can work on your cardio with some treadmill, exercise bike or rowing machine sessions, or you can focus on building muscle. You can also take a functional approach, training muscles for the tasks they perform in everyday life, rather than the gym (this method also builds some impressive-looking muscles as a happy byproduct).
This HIIT workout from the functional specialists at F45 Kingston takes the latter approach, basing the session around compound exercises which target multiple joints and muscle groups at once. It will take just under 30 minutes to complete, making it ideal for a lunch break. If you find it a bit easy, try this more advanced AMRAP workout from F45 Kingston.
How To Warm Up For This Workout
If you’re going to get the most out of a HIIT workout, you need to be firing on all cylinders from the start, and that means doing a proper warm-up beforehand. Now, you might well be doing HIIT because you’re short on time to exercise, but trust us when we say that a worthwhile warm-up need only take a few minutes.
The key to a good warm-up is thinking about the specific muscles you’re about to use and focusing on getting those muscles ready to go. Ahead of this HIIT workout you’ll want to start with some dynamic stretches – here’s a great seven-move warm up routine to use – and then go into a few exercise-specific warm-ups. The simplest way to do this is to run through a round of the exercises from the workout you’re about to do, completing just a few reps rather than working flat-out to time, and reducing the weight you’d use for any move that calls for a kettlebell or dumbbell.
Once you’ve done that, you’ll be able to hit your first circuit proper at full speed safely. If that means your workout is 40 rather than 30 minutes, that’s a fair trade-off. And if you really do only have 30 minutes max, then it’s usually smarter to shorten the workout than to skip the warm-up.
Functional HIIT Workout
The circuit involves nine functional exercises, most of which are bodyweight exercises, although you will also need a kettlebell and a pair of dumbbells.
For each exercise complete as many reps as you can within 35 seconds, then rest for 25 seconds before moving on to the next exercise.
Complete three rounds of the circuit. If you’re not sure how to do any of the moves click the header for a full explanation, and make sure to bear in mind the dos and don’ts from the F45 coaches.
