4. Squat Jump
Targets: Quads, glutes, cardiovascular system
How To: Start standing tall with your feet hip-width distance apart and your core engaged. Squat back as if you were preparing to sit down into a chair. Focus on sitting back into your heels. Be sure that your knees stay in line with your ankles. Once you’ve assumed squat position, quickly push through your feet and jump up as high as you can. Land lightly and quickly re-assume the squat position, jumping up and down at a quick pace for 8 to 12 reps.
