My favorite way to use this complex is in a challenge-style setting. It helps if you have a small group of 3-4 people to compete against, but if not, competing against the stopwatch will do just fine.
Dumbbell Hell Challenge
Dumbbell Hell – 3×10 (15-20lbs for women, 35-45lbs for men)
100 reps jump rope
The fastest any of my clients has ever finished the above workout in was 9:09. The average is about 16 minutes. Give it a shot and let me know how you stack up.
