Circuit training is one of the most efficient forms of exercise to burn fat, lose weight, and build muscle. You can sweat through a total-body, strength-boosting and calorie-torching workout at turbo speed, without even leaving your own living room. Not only is circuit training a super efficient way to work out, but it's also pretty much guaranteed to be a good time. With endless ways to customize and mix up circuit training sessions and the quick pace at which you move, it really never gets old.

Circuit training is a style of workout where you cycle through several exercises targeting different muscle groups with minimal rest in between. The result is a workout that taxes your muscular strength and endurance and your cardiorespiratory system.
