The toe toucher is similar to the V-up exercise. The difference is that the upper torso doesn't come off the ground quite as high, making this exercise a bit easier to perform. There are three parts to this exercise: a leg raise, a pullover, and an abdominal crunch. Instructions for advanced toe touchers are as follows:

Lie down on your back. Grasp any form of weighted resistance (med ball, barbell, etc.) and extend it past your head. You can also extend the weighted device straight up into the air. Doing so will eliminate the "pullover" arm motion. Next, contract the abdomen by lifting both legs off the floor. As your legs go up, take the weighted resistance device and try to reach for the toes. If you cannot reach your toes, aim for the ankle or shin area, then slowly lower your upper body and legs down to the ground. Repeat as needed.
