Minimize Back Strain Skip the tiring plate-loading altogether and leverage this bad boy to save your energy for your next PR. Easily center your bar without the heavy lifting (that comes later). Easy Bar Centering Heavy-duty nylon rollers and protective UHMW makes it easy to adjust your placement without tearing your barbell apart. Gently push that loaded bar and watch it slide smooth like buttah! Faster Plate Changes A deadlift jack holds your bar off the ground, giving you enough space between the plates and your floor so weight changes are a breeze. Just line up, scoop, and load-that's the power of leverage, baby!
