Narrow 
Jumps

What it hits: Glutes, Quads and Calves

Crash course: Just like pop squats, narrow jumps can strengthen your glutes and quads, which in turn could help you burn calories more efficiently and effectively.

Make it work: Stand with your feet together. Squat down (ensuring knees do not extend past your toes) and then jump up as high as you can. Land in a squat position (keeping all weight in your heels) and immediately jump again.

The rules: 20 reps
