These gymnastics loops from IWA are perfect for stretch bar training. The loops are made with a "1/2 turn" in them (see example) so they pinch less around the wrist. Each size has its own color.

Note: Replace your loops at least once a year. Check your loops before each use! Replace gymnastics loops immediately when they have damage or wear.
