Abstract: The present invention is related to sports training devices and, more particularly, to an arm training device for use in running related sports. The purpose of the invention is to hold the arm as close as possible at a 90 degree angle while running. The device comprises of a pair of poly-elastic webbing that is attached to both arms. The device is connected by a central segment. The central segment is attached to the lower wrist and upper bicep crease by buckles that the webbing is inserted through and then attached by velcro to create a loop. The loop can be adjusted to fit most arm and wrist sizes. The poly-elastic webbing holds the arm at almost a 90 degree angle while running. As result of the elasticity of the material, the arm will move forward and backwards faster while improving speed and technique.
