The present disclosure relates to apparatus and methods for applying resistance to the movement of a trainee using elastic resistance bands. The apparatus and methods may apply resistance to the trainee that increases substantially linearly while the trainee moves from adjacent the apparatus to distances of up to one hundred fifty feet. The apparatus may be portable and be used for athletic training, physical therapy, and general fitness by providing resistance to the trainee during the act of self-locomotion. The apparatus and methods also provide smooth extraction and retraction of elastic resistance bands over lengths in excess of one hundred fifty feet. |
