Defense On a String is a revolutionary team-defense training tool designed for both basketball and lacrosse programs that want to build disciplined, connected defenders.

Built with five adjustable waist belts linked by durable bungee cords, the system physically reinforces the concept of playing “on a string.” When one player rotates, hedges, slides, or closes out, every teammate feels immediate feedback — a subtle reminder to shift, recover, help, and communicate.

The result? A defense that moves as one unit instead of five individuals.

Why Coaches Love It


  • Teaches help-side principles naturally — Players feel when they’re out of position.

  • Builds muscle memory — Reinforces movement every time the ball moves.

  • Improves communication — Athletes learn to anticipate and react together.

  • Works for multiple systems — Man-to-man, zone, pack-line, motion defenses, and lacrosse slide packages.

  • Game-speed accountability — Instant feedback creates better habits in less practice time.

For Basketball Programs

Perfect for teaching:


  • Closeouts and gap help

  • Shell drill positioning

  • Ball-you-man concepts

  • Rotations and recoveries

For Lacrosse Programs

Ideal for reinforcing:


  • Slide packages

  • Crease help responsibilities

  • Adjacent and backside rotations


Defensive unit spacing

Whether you coach middle school, high school, college, or professional athletes, Defense On a String helps turn defensive concepts into instinct.

Stop coaching five individuals.

Start training one connected defense.
