Abstract: 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.

Abstract: Disclosed is a technical training garment configured for use with modular, interchangeable biomechanics units and or resistance modules. The garment may provide resistance to movement throughout an angular range of motion and or tracks a variety of biomechanical parameters such as stride length, stride rate, angular velocity and power expended by the wearer. The garment may be low profile, and worn by a wearer as a primary garment or beneath or over conventional clothing or athletic uniform. The device may be worn as a supplemental training and or diagnostic tool during conventional training protocols, or as a biomechanics or biometric data capture device during competition.
