Squat Thrust. This is one of those killer moves you might remember from P.E. back in the day. It's great for working your entire body while getting your heart rate nice and high. Work this into your usual cardio workout by doing 10 squat-thrusts every 15 minutes, or add some at the end of your workout. Do it right: Stand with feet together. Squat down and place your hands on the floor next to your feet. In an explosive movement, jump feet backwards into a push-up position, jump feet back between hands and stand up. Add intensity by adding a jump after you stand up. More intense cardio moves.
