发明名称 Reaction training belt with variable release resistance
摘要 A cost effective training belt that offers the ability to vary the release resistance and that allows the release resistance to remain relatively constant throughout the life of the belt. In one disclosed embodiment, the reaction belt has a first and second belt detachably secured together with a detaching structure that can connect the first and second belts together in at least two different ways. Each of the connecting ways offers a different release resistance; thereby a user can select the desired release resistance by selecting which way to connect the two belts together.
