1. A hip and leg exercise device comprising: a strap made of substantially elastic material, said strap having a proximal end and a distal end; a connector, with one end of the connector attached to the proximal end of the strap and the other end of the connector attached to an intermediate portion of the strap, forming a portion of the strap into a closed loop section having a constant diameter in a relaxed state with a remainder section extending away from the connector, wherein a diameter of the closed loop is less than six times a width of the strap, and the closed loop is adapted to wrap around both thighs of a user; an adjustment device configured to move along the length of the closed loop section and the remainder section, without changing the diameter of the closed loop section, such that the adjustment device fixes a portion of the remainder section to overlap with a portion of the closed loop section, such that the user can adjust a resistance of the exercise device by sliding the adjustment device along the length of the strap to increase or decrease the amount of overlap.
