The Byrdband Arm Trainer

What is Byrdband? 
Byrdband is an arm trainer that teaches athletes how to hold their arms at the proper position while running. It is made of poly-elastic webbing that attaches to the bicep crease and the wrist. Also, it is adjustable to fit all sizes.

How does it work? 

One of the most difficult challenges for advance runners and beginners is proper arm action. Byrdband creates the perfect arm action very simple and easy by preventing the arms from dropping, crossing, and being held too high.
