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