Spiders are a new type of exercise focused developing core strength while delivering a great upper body workout as well. Many folks perform Spiders on the floor without any elevation off the ground but the JACKRACK provides the perfect platform to ensure a secure hand grip and sufficient ground clearance to perform full Spider extension without dragging your knees on the ground.
