When you’re short on time but still want to squeeze in an effective sweat, turn to circuit training. The minimal rest periods mean you’re not counting down the seconds to your next set, and you’ll raise your heart rate and keep it high to improve your cardio fitness.
To work on your strength as well, keep this kettlebell circuit to hand. It’s from personal trainer Matt Tralli, who’s trained celebrities such as Tom Holland, Jacob Elordi and Dua Lipa.
