I love "anytime" moves like these that make me feel insta-strong. (Try a few at 3 p.m. when your brain is feeling melty and your bum is half-asleep.)
- Stand with your feet shoulder-width apart.
- Squat down, bending your knees to 90 degrees.
- Now jump up and land softly again in the squat position. Use the strength in your legs and butt to jump up explosively.
- Remember to land as softly as you can with your knees bent; keep your weight back, over your heels.
- Do 3 sets of 8 reps.
