Circuit training workouts have the notoriety of being some of the most intense workouts ever. They often combine heavy lifting and high-intensity cardio, giving you as much bang for your back as you can manage. What’s great about the workouts is that they are short. After all, at that level of intensity, going for a long period of time is too physically demanding for most people and may do greater harm than good.
AMRAPs: With an AMRAP (which stands for “as many rounds as possible”), you are given specific exercises to do in a given period of time — usually 30 minutes or less. The goal is to do as many rounds of them as you can in the allotted time. Give one (or all) of the following a try.
1. AMRAP for 20 minutes: 15 kettlebell swings, 10 mountain climbers per leg, 5 thrusters (dumbbells or kettlebell)
