The invention is a strap-based suspension exercise system that includes a main strap that is attached to a fixed or stationary object to anchor the exercise system and exercise straps that are used to perform a variety of exercises. Different main straps are provided that enable anchoring the exercise system virtually anywhere. The exercise straps, which may be inelastic or elastic are attached to the main strap using a uniquely designed buckle and include a safety strap. Various optional equipment, such as a foot hammock, a wrist or foot strap, additional handles, exercise straps with gym rings, and a vest worn by the user are provided.

A system for physical mobility activity of a person includes at least one fixed support member and at least one contact member to be worn by a person in motion. The support member and the contact member include at least one support surface and at least one contact surface, respectively. The support surface and the contact surface constitute the respective components of a hook-and-loop fastening connection including of hooks and loops, wherein the hooks have hook stems and hook openings. The hook openings on the support surface or contact surface in question are at least substantially all situated at the same side of the hook stems in question, when considered in a first direction parallel to the support surface or contact surface in question.

Disclosed herein is a device for protecting a climbing rope comprising a flexible sheath comprising a first edge, a second edge generally opposing the first edge, a first end, and a second end generally opposing the first end, a sheath connector assembly attached at the second end of the flexible sheath, and a primary rope connector assembly attached to the sheath connector assembly. Methods of making and using the device also are described.

One embodiment of the present invention relates to an improved camming stem system including a head member, a plurality of cam lobes, a connection system, and a retraction system. The cam lobes may be selectively rotatable between an extended state and a retracted state with respect to at least one axle of the head member. The connection system may create an elongated, substantially rigid region by intercoupling the head member with a loop. The connection system is configured to create an elongated partially rigid region by intercoupling the head member with a loop, wherein the connection system comprises a twisted cable coupled between the head member and the loop, and wherein the loop is oriented substantially parallel to the at least one axle, and wherein the twisted cable includes a twisting radial angle of at least 90 degrees.

Devices formed from interconnected components. Each assembled device comprises a yoke component, a boss component and an axle bolt. The yoke component comprising: a. carabiner body that includes a back, an opening, and a yoke formation. The yoke formation is constituted by a U-shaped section that is open to the outside of the body, and which defines a space between two legs, the legs having bearing surfaces through each of which a respective axle bore is formed. The back extends from the yoke formation to an end at a first limit of the opening. A spur extends from the yoke formation to an end at a second limit of the opening. A gate on the body can pivot between a closed position, in which it closes the opening, and an open position in which an object can be passed through the opening into a space within the body. The boss component has flat, parallel external bearing surfaces, an axle bore extending through the boss component, the axle bore opening at each bearing surface. The axle bolt passes through the axle bores in the yoke and boss component.
