Abstract
Abstract A training device which is particularly adapted to be drawn behind a vehicle and wherein the speed of movement of the training device may be varied is described. The training device is particularly adaptive for training people in running exercises and is constructed to take a varied portion of the weight of the person who is training while permitting the arms and legs to function in a normal manner as required by the training exercise. The device is also provided with an arm exercise device which can be utilized during the running exercise and thereby strengthening one's shoulders and arms. The device is usable for all types of training exercises including rehabilitation, and is adjustable to individuals of different height.
