Ripping out old carpet and rolling in the new simultaneously works up a sweat and uses muscle, like circuit training at the gym. But since much of this work keeps you on the ground, take a few moments at least once to stretch your hardworking legs and back. Stand with your right leg crossed over your left and the outside of your feet together, and bend forward with your rear knee straight. Hold the stretch for 15 to 30 seconds, then cross your left leg over your right and repeat.
