Repeat this circuit 5 times.20 reps of Hanging Knee Raises (from pull up bar/dip station) or Leg Raises (laying on the back on the exercise mat)
4 minute interval skipping (10 sec off /20 sec on for 8 rounds)
I didn't bother to count my skipping today, just pushed myself as much as possible. I altered between high knee skipping, regular, jump rope jack and scissors for each circuit.
Average time I completed this whole workout was 25:20.
