20. Jump squats
Make sure to use your whole foot to jump, not just your toes. Your goal is 3 sets and each set includes 20 reps with 30-second rest.
STEPS:
1. Stand with your feet shoulder-width apart.
2. Start by doing a regular squat, then engage your core and jump up explosively.
3. When you land, lower your body back into the squat position to complete one rep.
