MRT (metabolic resistance training) is a term covering various combinations of cardiovascular and muscular training. MRT can involve supersets, circuits, speed, low rest and compound movements; it almost always packs a double-punch of aerobic and anaerobic work, breaking down barriers between traditional weight training and cardio. If that sounds terrifying, don’t worry. All the movements and workouts in the MRT class are scalable for any fitness level. If you’re sick of long rest periods and the sleepy treadmill slump, MRT might be for you.
