Burn Fat and Build Lean Muscle With This 30-Minute Abs and Lower-Body Strength Workout

• Stand with your feet together and your knees soft. Jump and come into a lunge with your left leg forward.
• Push off with both feet, jumping them together, then hopping into a lunge with your right leg in front.
• Jump your feet back together to complete one rep.
• Repeat for 40 seconds, then take 20 seconds of rest.

If you find plyo lunges hard on your knees, do alternating back lunges instead.
