Abstract: A mechanism for adjusting the length of two straps making up a strength trainer of the type having a hand or foothold connected to a first strap and a second anchored strap. The mechanism has a rectangular ring mounted to move through a cross member engaged with a housing by a spring extended between the ring and the housing. A first strap is looped around a first member of the ring, while the second strap passes thought the ring below an opposite member and wrapping the cross member to pass through the ring a second time after passing between the opposite member of the ring and the second member so as to engage two high friction surfaces on the cross member and one on the ring. Adjustment is by rotating the housing and ring to be perpendicular to the load to unload the second strap from the high friction surfaces.

Abstract: A core wheel exercise device has a wheel with an axle and a shaft which extends through the wheel axle to which are mounted two handles. The handles in an extended configuration may be gripped or engaged by a user for exercise purposes, and in a collapsed storage configuration are aligned parallel to the wheel radius with a collapsed length equal to or slightly longer than the wheel radius so the core wheel may be supported on the ends of the handles. The handles are moved from the extended to the collapsed configuration by pushing the handles toward the wheel along dovetailed grooves in blocks on the shaft, allowing the handles to be rotated perpendicular to the shaft for storage. The blocks have an extension on one side of the shaft so the handles support a user so the handles cannot collapse under the load.

Abstract: An agility ladder exercise device has plural rungs which are connected by spaced flexible straps. Each rung has a left connector and a right connector, the left connector having structure thereon which engages with a right connector of a similar rung in a non-pivoting connection. The one or more ladders may be laid out on a play surface for use in agility exercises where the rungs of each ladder are spaced parallel to one another. Multiple ladders may be connected side to side, and can change lanes, or form a zig zag path. The ladders are stored with the rungs stacked parallel to one another within a holder with a U-shaped base. Each holder has connectors allowing a pair of holders to be releasably connected, and has a necked down region defined by restraint walls that engage with notches in the rungs.

Abstract: A collapsible exercise hurdle, an exercise mat compatible with the exercise hurdle, and a method of collapsing the exercise hurdle are disclosed. In one embodiment, the exercise hurdle can include a first hurdle panel, a second hurdle panel, and a hurdle spacer. The first hurdle panel can be coupled to the second hurdle panel. The first hurdle panel can comprise a first panel frame. The second hurdle panel can comprise a second panel frame. The exercise hurdle can have an expanded configuration and a collapsed configuration. The first panel frame and the second panel frame can be twisted into overlapping coiled rings when the exercise hurdle is in the collapsed configuration.

Abstract: An exercise cable handle assembly is disclosed comprising a locking mechanism including a handle base and a flexible retaining clip. The handle base comprises a cable opening and two side clamps defining a locking channel. The two side clamps comprise gradated edges. The flexible retaining clip is U shaped and comprises at least one curved hook end configured to engage with the gradated edge when the flexible retaining clip is positioned in the locking channel. The exercise cable handle assembly further comprises a segment of an exercise cable comprising a tapered plug along the segment of cable and a handle frame coupled to the handle base. The locking mechanism secures the segment of the exercise cable to the handle base when a portion of the tapered plug is positioned in the cable opening and the flexible retaining clip partially surrounds the tapered plug when positioned in the locking channel.

Abstract: A handle assembly base has a central tube opening for receiving an elastic resistance tube with an expanded end diameter. A first block and a second block are pivotably mounted to the base on opposite sides of the central tube opening. When pivoted towards each other, the blocks define a reduced area opening through which the expanded end diameter of the resistance tube cannot pass, thereby retaining the resistance tube to the base. The base has two opposed ears which extend upwardly of the central tube opening. A flexible strap is secured to the ears, and extends through a cylindrical tube to which a flexible handle cushion is mounted to provide a grip for the user to engage the handle.
