Our donations from proceeds our our Dam Duck Race are already at work. These are plyo boxes. A plyo box is a piece of training equipment used for plyometric exercises, which are a type of explosive power training that uses muscle elasticity to produce rapid, forceful movements. A plyo box can be any elevated platform suitable for plyometric exercises, but it needs to be level, sturdy, and capable of handling repeated strong yet softer impacts. Donated to Adirondack Health Medical Fitness Center.
