Exit Speed - MACH 3

Professional - 27”x27”

Our largest swing developer, also constructed with heavier materials and stitching for additional ruggedness and resistance.

The Exit Speed swing developer is a revolutionary training aid that rethinks how softball and baseball players build strength and hitting power. Advancing the traditional donut weight, Exit Speed utilizes a durable terry cloth parachute that creates drag throughout the extension and finish of the swing, providing complete resistance for the duration of the swing.

Now you’re building strength, not using momentum, to follow through.
