GRGL SHREDmill Performance Package

Focused sprint training for student athletes

This package is designed for student athletes who want to improve how they accelerate, transition, and move at top speed. Each session focuses exclusively on sprint mechanics and ground speed using the SHREDmill and GRGL’s purposeful coaching approach.

Session focus

• Force Production — Early Acceleration: Develop force application to support a stronger, more effective start.
• Force to Form — Transition Phase: Work on posture, rhythm, and mechanics as the athlete transitions from acceleration toward upright sprinting.
• Form — Top End Speed: Refine sprint mechanics, coordination, and movement efficiency at higher speeds.

Track & monitor ground speed

GRGL uses HUDL/Titan GPS to track and monitor each athlete’s ground speed during ground sprinting. These measurements help us assess progress over time and guide coaching decisions alongside the athlete’s SHREDmill training.
