- focus on lifting your back leg rather than dropping your chest
- be careful - these will rip up your hamstrings!
- I have yet to find an abdominal exercise that puts your abs under more duress, especially when done all the way to the floor.
- be light in your toes and quick with the rope. Practice different patters as soon as you master one.
- more difficult - keep your arms straight.
- more, more difficult - keep your knees straight and bring toes to the bar
