The Accelerator

Meet The Accelerator—the first and only training system featuring true “real-feel” weighted lacrosse balls engineered to elevate how modern athletes train, develop, and dominate.

This complete, performance-driven system is designed to transform your mechanics, sharpen your release, and build the strength and power demanded by today’s fast-paced game. Every rep is intentional. Every ball is built with purpose. And every athlete—from rising players to elite competitors—can unlock measurable, game-ready improvement.

The GLK Sports Training starter kit includes three specialized training balls:

• 145g Standard Ball: Establish consistent mechanics and build baseline form.
• 115g Reduced-Mass Ball: Increase release speed and sharpen quick-stick precision.
• 200g High-Mass Ball: Develop strength, power, and shot force through targeted overload training.

Your purchase includes access to a comprehensive online instructional guide built for all skill levels. Beginners can start with a simple, 20-minute routine using all three balls—and immediately experience the difference.

Improving shot speed is just the beginning. This system delivers a wide range of benefits that will be fully detailed under the “Does The Accelerator Work?” page.

A separate 250g training ball is available for athletes seeking an advanced challenge, and additional weighted options will be released in the coming year.
