A portable exercise device includes a first body and a second body. The exercise device also includes a support structure pivotably connecting the first and second bodies. The support structure is configured to move between an engaged position and a disengaged position. The device also includes a resistance mechanism configured to resist movement of the first and second bodies toward one another when the support structure is in the engaged position. When the support structure is in the engaged position, the first body is positioned substantially parallel to the second body such that in a first open, in-use configuration of the device, the first body has a first neutral position relative to a pivot axis and in a second open, in-use configuration of the device, the second body has a second neutral position relative to the pivot axis.

A portable exercise device includes a pedal pivotably connected to a pair of supports. The pedal has a neutral position relative to a pivot axis. The pedal is configured to rotate about the pivot axis in a first direction toward one support and in a second direction, opposite the first direction, toward the other support. The exercise device also includes a resistance mechanism configured to exert a force on the pedal about the pivot axis in a direction opposite to the respective direction of rotation of the pedal about the pivot axis. The device is movable between an open, in-use configuration, where the pedal is disposed in the neutral position to receive a foot of a user and the pair of supports together form a triangular base, and a closed configuration, where the pair of supports are flush against the pedal.

A functional triangular apparatus for multi-exercise of lower and upper extremities using resistance bands encircling designated parts. When exercising legs the triangular apparatus is stationary or tilted back at various angles to balance on two feet. Arms exercise with stretch bands under elevated larger base while feet hold it down.

A foldable, portable sports goal structure includes a hollow frame that contains an elastic cord or cable that uses compressive forces from the cord tension to hold the frame together. The sports goal includes ground support bars, sidebars and a crossbar. Rear support bars may also be used. The elastic cord or cable that is under tensions is used to hold the frame together when the goal is set up. The elastic cord or cable also holds the frame together when the goal is folded up so the goal can be quickly set up or folded up. The net can remain attached to the frame, which allows the goal to be used or stored as a single unit.

An exercise system comprising an extension section and a base section. The base section comprises a support assembly, a sleeve assembly, and a resilient member. The resilient member is arranged to resiliently oppose movement of the sleeve assembly in a compression direction relative to the support assembly. The extension section is detachably attachable to the sleeve assembly. The exercise system is operated in at least first and second configurations. In the first configuration, the extension section is detached from the sleeve assembly. In the second configuration, the extension section is detachably attached to the sleeve assembly such that the resilient member resiliently opposes movement of the sleeve assembly relative to the support assembly in the compression direction.

The invention is that of a lacrosse ball collection apparatus fabricated from materials such as plastics, metals and fabrics. The apparatus comprises a fabric which when in its open position forms a substantially triangular horizontal surface capable of fitting inside a lacrosse goal. When lacrosse balls are shot into the goal, they collect on the fabric. The apparatus is foldable at a front joint and comprises a spout located behind the front joint and in close proximity thereto, such that the apparatus may be used to carry the balls to a collection receptacle, where they may be poured out of the spout into the receptacle for reuse. The apparatus is further foldable at two side joints such that an apical joint is foldable toward the front joint and two front member segments are foldable inward to render the apparatus in a compact, closed position suitable for storage in small spaces.

A system for dropping golf balls at pre-determined, repeatable patterns and distances from a hole or target for putting and chipping practice may include a removable ball holder and retrieval device to retrieve golf balls that have been struck for efficiently reloading the system for repeated golf ball dispensing.

Posture training systems provide hands-free shoulder and back\spine alignment assistance for facilitating correct posture and alignment of the shoulders and spine of an athlete throughout swing or other physical rotational movements, and methods of their use. The posture training systems include vests that provide information during and throughout the rotational movement about spine-tilt angle relative to the ground, plane of the shoulders during torso rotation, perpendicularity between the spine and a line drawn between the shoulders, as well as departures from or maintenance of any of the initial parameters.
