It's not much of a stretch to say that nobody knows how to build power, speed, strength, and flexibility better than Jillian Michaels. This comprehensive workout, which she created for Health, trains the muscles in a way that will bust through even the most persistent plateau. Do it four times a week, paired with 20 minutes of high-intensity interval training, and watch your body be transformed.
