Vertical jump comes from force production through the hips, knees, and ankles — and resistance during the jumping motion itself is one of the more direct ways to train it. Running the bands from shoulders to heels loads the full triple-extension chain rather than isolating one joint.
The resistance works both ways: it makes the concentric jump harder, and it pulls you back down faster, which trains the eccentric absorption that landing and reactive jumping depend on. That combination is what separates jump-specific work from general leg strength.
Sized for youth, high school, and college or professional athletes so the resistance matches the athlete rather than overloading a developing frame. Used for basketball, volleyball, and any sport where getting off the floor faster matters.
