Abstract
Methods and devices for isolating muscle groups during exercise are provided. According to an aspect of the invention, a device includes a first strap that has a first loop shape, a second strap that has a second closed loop shape defining a fixed opening, and a third strap that has a third closed loop shape. A first portion of the first strap is affixed to or integral with the second strap, a second portion of the first strap is arranged to be movable within the fixed opening defined by the second closed loop shape, the second portion of the first strap is affixed to or integral with the third strap, and a first adjustable opening within the first loop shape is configured to be adjusted by changing a relative position of the second portion of the first strap and the fixed opening defined by the second closed loop shape.
IPC Classes ?

Abstract
An exercise device is provided to couple a user's limb to a resistance mechanism and to tighten on the user's limb by a force applied in opposition to the resistance mechanism. The device may include a strap including a first portion, a second portion, and a third portion. The strap may define an adjustable opening configured to receive the user's limb. The first portion and the third portion of the strap may be attached to a closed loop shape configured for coupling to the resistance mechanism. A fixed opening may be coupled to the strap, and the adjustable opening of the strap may be formed by passing the second portion of the strap through the fixed opening. The device may also include a flexible material coupled to the strap and defining a tube providing the fixed opening.
IPC Classes ?
- A63B 21/00 - Exercising apparatus for developing or strengthening the muscles or joints of the body by working against a counterforce, with or without measuring devices
- A63B 71/00 - Games or sports accessories not covered in groups
