Forget the gym — you only need 1 kettlebell and 20 minutes to strengthen your entire lower body

You don’t need any weights at all to build muscle, but if you can get hold of one kettlebell, it will instantly increase the effectiveness of your strength workouts. The best kettlebells are versatile bits of kit that you can use for pure strength sessions as well as HIIT workouts, and one is all you need to build power throughout your body.

This 20-minute workout from fitness trainer Kat Boley is focused on the lower body, and so she recommends using a fairly heavy weight — Boley is using a 40lb kettlebell for reference. The workout targets all of the major muscle groups in the lower body through a series of compound exercises, and using a heavier kettlebell means that you’ll sufficiently challenge these large muscles.
