This is a 3-day bodyweight routine that is meant to be short but challenging. All sessions are less than 15-minutes long. Each workout day is more challenging, though, compared to the previous session. All three workouts are performed as supersets for two rounds. Day 1: The workout is about 12-minutes long, all interval sets are 35-seconds ln length. This is the easiest of the three sessions. Day 2: The workout is about 13-minutes in length, and offers basically the same movement patterns in terms of exercises. Each interval duration is now 40-seconds. Day 3: This session is the most challenging of the three. Once again, you'll perform 6 exercises, but the duration of each one, is now 45-seconds and the exercises are more challenging. This is also the longest of the three workout days (15-minutes). Stay Strong, MICHAEL WOOD, CSCS Jefit Team
