The Best Gadgets to Make You Slim
How-to: Box Jump
Stand facing a 12- to 18-inch plyo box with your feet hip-width apart. Push your butt back and squat down until your thighs are almost parallel to the floor (A), then push strongly into your feet to jump up onto the box, using your arms for momentum. Land gently in squat position (B), allowing the toes of each foot to hit before your heels (your feet should land at the same time). Push off with your heels and jump back down, landing softly, toes first, in squat position. Repeat for 30–60 seconds (depending on your strength)
No gym or plyo box? Do the move using a sturdy step or low bench. Or, skip the equipment and simply jump forward and backward instead of up and down.
