15-minute metabolic circuit for muscle and calorie burn.

A 15-minute metabolic circuit workout can help burn calories and torch major muscle groups. Metabolic training involves aerobic and anaerobic exercise, and it could be the secret to calorie burn and fat loss. The workout includes five compound exercises, such as medicine ball slams, jumping rope, push-ups, dumbbell walking lunges with burpee, and dumbbell snatches. The payoff includes improving energy systems, increasing power, building strength and leaner muscle, and sending the body into calorie-burning mode.
