THE prostrap -
THE STANDARD
FOR THE PRO KINETIC CHAIN
Master your form with The ProStrap—the tennis training tool designed to improve swing mechanics, increase power, and build muscle memory in minutes. Engineered as a kinetic tether system, the ProStrap physically connects your wrist to your hip to create a "dynamic constraint" that mechanically eliminates the ability to "arm the ball." unlike static resistance bands, it forces the body to rotate as a single unit.
Trusted by coaches and players worldwide, it is the proven way to develop consistent, powerful strokes fast.
Welcome to the future of Tennis Training.
THE PROBLEM: KINETIC DISCONNECT
The single greatest failure in amateur tennis is Arm Dominance. Instead of leveraging the body's large muscle groups (Legs, Hips, Core), most players isolate the arm to generate force. In biomechanics, this is known as a "Broken Kinetic Chain."
From a technical standpoint, this causes numerous problems when striking the ball:
Collapsed Spacing: Contacting the ball too close to the body ("Jamming"), destroying leverage.
Late Contact: Striking the ball behind the ideal kinetic window.
Static Rotation: Zero engagement from the hips and shoulders, forcing the small muscles of the arm to do all the work.
The result is weak output, erratic control, and a massive increase in chronic injury risk (Tennis Elbow/Wrist Strain).
THE GOAL: KINETIC LEVERAGE
Elite ball strikers do not generate power with the arm. They utilize Rotational Physics.
The defining characteristic of a pro swing is "Spacing"—keeping the elbow away from the body to create a longer lever. In physics, the longer the lever, the greater the force generated at the end of the arc. The body creates the torque; the arm is merely the delivery system.
The "Whip" Effect
Crucially, the arm must remain loose to transfer this energy. You cannot create a "whip effect" with a rigid limb. The ProStrap forces this spacing while keeping the arm relaxed, allowing you to generate massive spin and power using body weight alone.

“I’m a huge fan of it. What the Prostrap does is really, really hard to teach. It’s such a great device… It’s really one of the better ones I’ve used. Maybe the best.”

the solution:
the prostrap
Most training aids are static constraints—they confine you to shadow swings or rigid poses. The ProStrap is designed for live combat.
It is the first and only system that allows for full-speed groundstrokes during live training sessions. Whether you are drilling on a ball machine, drop-feeding, or training with a coach, the ProStrap applies constant kinetic feedback "under load."
This bridges the gap between feeling the correct form and executing it in a match.

How the prostrap works -
The ProStrap operates on a binary feedback loop: Tension vs. Slack.
To execute the shot, the tether must remain tight through the entire contact zone. This physically forces the player to maintain critical spacing between the elbow and the hip.
Tension (Correct): If the cord is tight, your kinetic chain is connected, and your body is rotating correctly to generate leverage.
Slack (Incorrect): If the cord goes loose, you have "jammed" yourself or disconnected the hips.
This immediate tactile response forces the body to self-correct instantly, shifting the workload from the small muscles of the arm to the massive power sources of the core and legs.
Customizable Radius The system includes interchangeable tethers of varying lengths, allowing players to dial in the precise spacing required for their height and swing style.
The laws of physics do not change based on skill level. The ProStrap is standard equipment for every stage of player development.
Foundational (Beginner/Junior): Installs the correct kinetic chain before bad habits form. It acts as physical "training wheels" for rotation.
Calibration (Advanced/Pro): Used as a diagnostic tool to fix timing issues, "check" spacing under pressure, and restore the "heavy ball" feeling during slumps.
Instructional (Coaches): Eliminates the need for verbal over-coaching. Instead of telling the student what to do, the device forces them to feel the correction instantly.
Kinetic efficiency isn't just a feeling; it produces data.
By connecting the kinetic chain, players see an immediate increase in RPM (Spin Rate) and Velocity (MPH) with less perceived effort. The ProStrap doesn't just fix your form—it upgrades your ball quality.
