A 10-Minute Leg Workout That's Just 4 Moves

You might consider this just a burpee without a push-up, but we love how this full-body exercise works the legs and the abs while raising the heart rate a bit too.

• Begin standing, with your feet hip distance apart.
• Lower into a crouching squat, with your hands on the floor.
• Keeping your abs engaged, jump your feet back so you're in plank position.
• Keeping your arms straight, jump your feet forward behind your hands.
• Stand up to complete one rep. Do eight reps.
