The LSS Cotton Lifting straps are cotton strips you use to wrap around your wrist with extra length pointing toward the palm of you hand. You wrap the extra length around a dumbell or free weight and tighten it up so the heavyness of the weight doesn't go into your fingers but your wrist. Helping you lift more weight without the constriction of having to support 100+ pounds on your fingers alone. The cotton is a cheap material to make these out of because they can rip when the weight gets heavier, I'd suggest leather straps instead if you are serious into weight lifting because the material is thinner and can support more weight. For a cheap alternative these do very well, and will work just great for the casuaul weight lifter. Very useful.
