The original design for the SpeedChain began as a device to increase golf swing speed and the concept proved effective for increasing bat speed. The basic concept of SpeedChains, whether for golf, baseball, tennis, or any other sport, is based on movement specific variable resistance. With the Baseball Bat Speed Chain, movement begins with lighter chain links allowing high acceleration and progresses to heavier gauges of chain requiring maximum force as movement passes through the hitting zone. The result: increased bat speed and power at the plate.
The Bat Speed Chain is available in four sizes:
- Light – Typically used by beginning hitters
- Youth – Typically used by pre-adolescent hitters
- High School – Typically used by high school hitters
- PRO – Typically used by collegiate hitters
Muscularly mature athletes (including those considered strong for their age group) should consider using a heavier Bat Speed Chain. Athletes taller than 6'4" should add extensions to this product. Chain ends should never be allowed to come off the ground/floor or gather around the feet during exercises.
