Here is another training tool that helps football players improve their hand placement and striking techniques. The Difference Striking Pad is made from 3/16th A36 steel with a nickel-plated inner tube. It is weather resistant for indoor/outdoor use. 4 different custom spring tensions are available (green, white gray and black from 15 to 150lbs)
The springs are made of wire and powder coated. They can be quickly swapped to adjust the system to athletes of varying size. You can order yours on Rogue Fitness.
