Original StrechCordz with Handles, Swimming Resistance Bands, Dryland Training, 5 Resistance Levels

Tubing is 1/2" o.d., strong enough to provide all the resistance I want, built well so I do not have to worry about product failure and injury. It replaces an old, exact same set of blue Stretch Cordz...after many years, the black colored tubing began to degrade and it was time for a new set

Great piece of equipment

Excellent
