AMRAP, in 15:00, of:
40 Double-Unders
1/2 Length Handstand Walk/1 Length Plank Walk

If you are good at both movements, then go for speed. Othersise, use this time to purposefully practice.

20/15 Calorie Row, Ski or Bike
20 Burpee Box Jumps (24/20)
20/15 Calorie Row, Ski or Bike

Target finish time is 3:30-4:30. Choose a different machine after every time you complete 20/15 calories. If you aren’t able to finish in 5:00, then keep moving through as many rounds as you can in the 25:00.
