High Knees

What it hits: Hip Flexors, Quads, Glutes

Crash course: Performing this exercise can improve lower body power and flexibility while increasing your heart rate.

Make it work: Stand in place, feet hip-width apart. Drive your right knee into your chest and quickly place it back on the ground. As soon as your foot hits the ground you want to repeat the motion with the other knee. Continue alternating knees as quickly as you can go.

The rules: 1 minute as fast as you can go
