The Cardio Sofa workout uses your sofa for something decidedly different to couching out. A lower body workout with a strong aerobics component Cardio Sofa is perfect for that rainy day when you feel like going for a run but the weather is against you or when you really don't want to go into all the trouble associated with tidying yourself up so you can go outdoors. Get into the sweatzone fast by making sure your knees are waist height during High Knees and you are really pumping your arms. And go EC for that extra pressure on your recovery time and your VO2 Max.
Extra Credit: 30 seconds rest between sets.
