CREATE A PLAN
Rev your fat-burning engine with this challenging training session.
In the routine that follows, you'll lift weights using "alternating sets," in which you perform one exercise followed by another and alternate between moves. For instance, you might do a set of squats, rest briefly, and then do a set of rows. You can minimize your rest between sets with this approach because you use different groups of muscles to perform two distinct movements.
Besides limiting fatigue, this strategy allows you to train faster than you would normally, performing typical "straight sets," in which you do a set of one exercise, rest a couple minutes, and repeat the same movement.
With alternating sets, you maximize how much work you're able to do in a given time period, a concept known as "work density." Increasing the density of your training session increases the demand on your metabolic system so you burn more calories, lose fat, and spike your metabolism.
