Back in 1998, Bodylastics pioneered the Resistance Band Clip System. Take a look below to see how it works:
To attach your Clip resistance Bands to the handles and ankle straps simply clip them on to the metal rings.
Attaching The Bands:
To increase resistance, simply substitute the elastic for a thicker one (thicker = more tension), or "Stack" the resistance by clipping on (combining) multiple bands.
To decrease resistance, simply change out the elastic for a thinner one (less tension), or removing additional bands which are attached.
