JACKKNIFE V2

February 8th, 2010

Compulsive Knife Use – A classic no-kit exercise that targets both the upper and lowers abs.

You can view the original Jackknife stretch.. this version is upgraded, sleeker, sharper and better in several ways..

1. Lie on your back with your arms and less held just off the floor
2. Bring your arms and legs up, keeping them straight, to meet above your stomach.
3. Lower yourself back to the starting point slowly.. to avoid any injury.. and make sure you keep your arms and legs straight.
