Some embodiments include a strike training
machine that provides bidirectional resistance. The
machine replicates the full and natural trajectory of the striking motion and provides resistance throughout extension and contraction of the striking motion. In this manner, the
machine trains all muscles involved in a particular strike. The trajectory of the machine is user adjustable to accommodate different striking motions which include punches, kicks,
elbow strikes, knee strikes, and throwing motions. In some embodiments, the machine applies a user specifiable amount of resistance. By adjusting the amount of resistance, the actor is able to overload
train the
muscle groups associated with the striking motions by gradually increasing resistance during training.
