Vertical jump enhancement system

摘要

The present invention relates to a plyometric training device that is simple in construction, inexpensive and easily portable. The plyometrics training device of the present invention includes a harness for attachment to a user and a pair of resilient cords attached to said harness to resist the vertical movement of a user as the user jumps vertically upwardly from a surface. In the preferred embodiment, the resilient cords have free ends that can be attached to a pair of ground anchors or a pair of door anchors or that can be stood upon by assistants to anchor the cords. In the later anchoring method, hand grips are provided that can be gripped by the assistants and the resilient cord is sufficiently long so that the cord is anchorable by passing underneath at least one foot of each of the assistants and gripped at the hand grips.
