Lightweight, compact and portable, the tubing exerciser helps perform strengthening and conditioning workouts on-the-go, even in your hotel room. Two permanent foam covered rigid handles give the exerciser comfort and a firm grasp. CanDo is licensed to use the Thera-Band® color sequence so resistance level is easily identified. The BowTie exerciser is available in 7 levels of resistance  for progressive exercise and 3 lengths to accommodate different needs. Levels range in order of strength from least to greatest resistance: tan, yellow, red, green, blue, black, silver. Length represents length of tubing from end to end when unit is laid flat and is taut. CanDo® low powder exercise tubing is made of natural rubber latex, which may cause allergic reactions.
