Abstract: A training device includes a tether having inelastic portions disposed between its ends, where each inelastic portion is separated by an elastic portion, and where each of the ends is configured for engagement with hands of a trainer. The training device may include a belt that wraps around an athlete's body, the belt including a ring on a back portion thereof having an opening for receiving an end of the tether therethrough. When the belt is secured around the athlete's body and the tether is disposed through the ring, the training device may create a coupling between the trainer and athlete when the trainer secures the ends of the tether. The coupling may be substantially released when the trainer releases one end of the tether such that the released end is substantially unrestrained to traverse through the ring thereby fully disengaging the tether from the belt.

The training device may include a belt that wraps around an athlete's body including a ring on a back portion thereof having an opening for receiving an end of the tether therethrough. When the belt is secured around the athlete's body and the tether is disposed through the ring, the training device may create a coupling between the trainer and athlete when the trainer secures the ends of the tether. The coupling may be substantially released when the first user releases one end of the tether such that the released end is substantially unrestrained to traverse through the ring thereby fully disengaging the tether from the belt.
