发明名称 Athletic movement trainer
摘要 An athletic movement trainer comprising a belt, ankle straps, and an elasticized, bungee-type cord. The cord passes through a ring, such as a screw eye, attached to the belt. Each end of the cord is adjustably connected to an ankle strap so that the cord will remain relaxed as long as the sportsman maintains the proper athletic position but will become tensioned when the athlete deviates from the correct posture or stance. Because the ring does not prevent all movement of the cord, the trainer merely resists, rather than restricts, the upward movement of the athlete. The trainer thereby "reminds" the sportsman to resume the proper athletic position without preventing him or her from deviating from the position when required.
