Availalbe for: iPhone
This full-featured app aids your workouts by teaching you exercises, encouraging balanced workouts, and keeping you optimally-paced. The app helps you select a balanced routine that tightens and tones your entire body and continually tweaks the sets and reps to match your abilities. A rest timer and vibration alerts let you keep your iPhone in your pocket while it helps you cool off, and iTunes control enables you to play your power songs without missing an exercise. You can try the dumbbell-only version free, but the paid version is certainly our favorite.
