To reduce body fat through exercise, you must get your heart rate high. To add size, you must place sufficient stress on your major muscle groups. These two goals appear mutually exclusive, which is why many think it’s impossible to lose fat and gain muscle simultaneously, so they either lift heavy with long rest breaks (great for building muscle but not for burning fat), or do a lot of cardio (good for getting into that fat-burning calorie deficit but devastating for developing big, full muscles).

But there is a solution, and it’s called Peripheral Heart Action (PHA) training. It’s a type of circuit training where moves alternate between working the upper body and lower body so your heart and lungs work overtime to shuttle blood back and forth between your extremities, and your muscles get a solid stimulating workout. Try this session on for size.

How To Do This PHA Workout

Do the six barbell exercises in order, sticking to the reps detailed, without resting until you finish all the reps of the sixth and final move of the circuit. Rest for two minutes, then repeat the circuit. Do four circuits in total.
