- 20 Mountain Climbers
- 20 Cycling Crunches
For mountain climbers substitute the jumping movement for a stepping action
Cycling crunches are like riding a bike, well sort of. While lying on your back cycle your legs (like riding) by bringing the knees in to the chest and pushing back out, place fingers behind your head and crunch from side to side to meet elbows with your knees.
