Abstract: A device for performing resistance exercises includes a non-elastic strap having a first end and a second end. The device includes a first stretchable member having a first end coupled to the non-elastic strap proximate the first end and a second stretchable member having a first end coupled to the non-elastic strap proximate the second end. The device includes a first adjusting mechanism disposed proximate the first end of the non-elastic strap and a second adjusting mechanism disposed proximate the second end of the non-elastic strap. The first and second adjusting mechanisms are manipulated to adjust the length of the non-elastic strap between the first and second stretchable members.
