Here at X bands I took the normal TRX set up and I upgraded it. In this setup there are 4 different length options all you do is take the handle and snap it onto which ever loop you want. Attached to the padded handle are loops so that you can attach your feet to do all your favorite ab workouts. Also the padded handles are detachable and can be used to attach to any resistance band or cables. Either you can attach it to our door attachment or loop it over any pole or other anchor.
