Run in place as fast as you can, pulling your knees up as high as you can. It is so fast paced that it shoots your heart rate up in seconds.
That is because you have to call on your big glute muscles to hoist your legs and keep you moving quickly. And don’t let your arms just swing. Pump them with all the power you can manage. That will help you pull your knees higher and activate upper body muscles, turning this into a total-body all-in-one workout.
Do 30 second rounds after each tone up move in your workout, or start a session with four or five rounds of 30 second sets.
How to nail it: Run in place, pulling your knees toward your chest and vigorously pumping bent arms.
