A power and stabilizing apparatus for rolling or sliding-based recreational activities is disclosed. The apparatus may include a shafted body coupled to a biased member. The biased member may be a bowed biased member or any other biased member configured to store and release energy during use of the apparatus. The apparatus may also include a shoe coupled to the biased member opposite the body, the shoe having a traction element coupled thereto. The body may be a shafted telescoping body configured to lock in an extended position and lock in a retracted position. The body may be coupled to the bowed biased member with a coupling member having a first leg coupled to the body and a second leg coupled to the bowed biased member.

A configurable handgrip has a plurality of plates, the plates being arranged in a stack, a clamp element operably engaging the stack, and the clamp element being operable to transition between a first released position in which the plates are free to move with respect to each other, and a second clamped position in which the plates are secured against movement with respect to each other, such that the stack may be formed into a selected shape when the clamp is in the released position, and the plates are held in the selected shape when the clamp is in the clamped position. Each plate may define a plate aperture. The clamp element may be an elongated member received in the plate apertures. The plates may each have a contact edge and an opposed recessed edge.

This novel, strapless hand grip is intended to be used with a Nordic walking pole or other walking stick to reduce hand, wrist, or other musculoskeletal strain. This invention is a hand grip in a largely cylindrical design with two thumb channels at the top of the hand grip, which provides a more natural position for the thumb. The two thumb position channels allow the user to choose between a grasp or pinch position. This invention has a curved platform extending from the lower section of the hand grip, which provides a cradle for the ulnar side of the user's hand. This cradle supports the hand and/or wrist and may reduce pressure on the trapeziometacarpal and radiocarpal joints by keeping the wrist in a neutral position. By incorporating the thumb channels and platform, a wrist strap is not a required component, further reducing possible stress and pain points.
