The majority of athletic drills I practice with clients prioritize speed and technique over short distances. This particular drill uses two jumpstretch bands tied together and anchored down to provide resistance as you back-peddle. This reinforces strength and speed because as the band begins to tighten, the runner must use his speed to counter the increasing resistance and beat the elasticity. I typically have clients practice this drill 5-8 times per set and the average 200 lb man can typically stretch the band to a little more than 5 yards.
