The Power Systems Power Sled has multiple training options, push it or pull it.  This Power Sled is the perfect training tool for developing explosive leg drive for elite performance. Incorporate this speed sled into sprint training drills to improve acceleration and increase stride length. S-shaped design generates less friction between sled and surface for faster runs. Angled tray directs force of weight downward, behind the front anchors, keeping sled stable. Dual leads pull sled straighter. Build powerful hips and legs using the handles or target stride length using the belt/harness. Perfect for forward, backward, and lateral training, the waist belt provides exercise versatility.
