Here are a series of exercises that employ a technique that I perfected called Resist/Assist,/Skill, which helped my NFL kickers to set the marks for longest field goals, to most touch backs on kickoffs, while helping Serena Williams to increase her first serve speed from 120 mph to 125.

This performance enhancement technique uses a simple but unique rubber tubing device with multiple points of attachment – The Functional Trainer. You will notice that as you move away from the anchor position, you experience resistance. On the return to position, you are assisted.
