This waist harness and leads set for the Rae Crowther Dragon Slayer football sled offers a way to train lower body resistance. Attach the belt to a player and the leads to a Dragon Slayer sled and run drills to develop speed and strength like working forward lunges, lower body resistance training with added weights (not included), or bear crawls. This harness is easy to attach to the Dragon Slayer strength and conditioning sled with its 11ft leads and carabiner clips and to the player with the adjustable hook-and-loop-style belt.
