Stand with your feet slightly wider than hip-width apart, holding the sides of the pillow. Bend your knees and jump up, swinging the pillow up overhead as you leave the floor. Land in a deep squat and chop your arms down, pressing pillow down to the floor (if you can get low enough, try to touch the floor with your pillow). Repeat as many times as you can for 1 minute.
Form tip: Focus on using the muscles in your feet as much as you can during this exercise. Try to jump up by pushing through the balls of your feet and then land softly, rolling through toe-ball-heel.
