What It Is
Short, all-out runs with rest between, the fastest way to build speed and push your fitness in little time.
How to Do It
Clip on the safety key. Sprint as hard as you can for the time given. To rest, hold the rails and straddle the belt on the side rails. Never jump off a moving belt. Raise the speed or the incline to reach the heart rate your coach asked for.
Skill Level
Advanced. Heavy barbell lifts, Olympic-lift variations or all-out sprints. They take precise technique under load.
Type
Cardio. Raises your heart rate to build endurance and heart health.
Engagement
Unilateral (Alternating). Each rep alternates between sides.
