Fitness Blender brings you this 60-minute workout comprised of the following: a five-minute warmup, 16-minute HIIT, 13-minute upper-body strength, 10-minute kickboxing, 12-minute core and cardio, and five-minute cooldown. You'll need dumbbells for part of the video but, otherwise, all that's required is an open space and an exercise mat if you're on hard flooring and want some support.
