I'm up to Level 7. Do each exercise in order - pull ups, then push ups, then squats. For Day 1 workouts, keep the timer going even if you stop to rest.
You move up to the next level if you complete the Day 3 workout in less than 5 minutes. If it takes you longer than 30 minutes, you move down a level. If you do it in more than 5 but less than 30, stay at the same level.
