This versatile tubing set is great for two-arm resistance exercises and allows you to simulate exercises performed on cable weight machines. These tubes can be used anchored in a door jamb or with the Web Slide® Exercise Rail System. Latex tubing has handles on each end. A rubber-saddle anchor strap extends the life of the tubing while securing it in either a door jamb or in the Web Slide Exercise Rail. Each set includes 1 tube of each resistance level with rubber-saddle anchor straps.
