The Title Boxing Spider Bag brilliantly combines all of the benefits of light bag, double end bag and defense training in one extremely versatile piece of equipment. Simply attach the four heavy-duty resistance stretch bands to the corner posts of any boxing ring or existing four poles in the gym or training area, and instantly create an ideal way to perfect punching and working off angles, slipping, ducking, bobbing, weaving, head movement and nearly every aspect of your offensive and defensive game. The line of the resistance bands enhances your footwork, both side-to-side and forward-back. Combined with the action of the air-filled center target ball, it forces you to think – and react - both offensively and defensively, honing and improving all your boxing skills to be an all-around better fighter. Genuine leather target ball is triple nylon stitched with leather welted seams for professional results. Comes complete with heavy-duty chrome O-ring attachments on each side and durable resistance bands.
