The Viking Boxing Reistance Striker is a unique train-while-you-play design is transforming the way athletes train. Comprised of a single Slastix that attaches through the shoulder harness to two punch cuffs, the viking boxing resistance stiker supplies built-in resistance and allows fighters full freedom of movement while performing punches, hooks, jabs, blocking, and virtually any other upper-body strike. This also improves the arms ability to repeatedly retract from a strike immediately to a defensive or offensive hand position. With Slastix-generated resistance against the key upper-body muscle groups, fighters build strength where they need it most, maximizing every second of training.
