The invention concerns exercise apparatus having a weight source (18) operably connected to a plurality of manual actuators (28, 32) by a cable and pulley system. The cable and pulley system (12) has a plurality of pulley wheels (16), a supporting frame (10) for the weight source (18) and pulley wheels (16), and a cable (22) defining a force path from the weight source (18) over the pulley wheels (16). The pulley wheels (16) and frame (10) are provided in a common plane with the weight source (18) at least when the exercise apparatus is not in use. The manual actuators (28, 32) are provided at spaced locations along the path defined by the cable (22) and are actuatable in a direction away from the common plane when in use. The frame (10) may supported in an upright orientation for use by a support structure, e.g. a wall, and may occupy a minimal space/depth.

The present invention is a portable resistance machine that allows a user to perform rowing, skiing, paddling, or any other physical activities at any suitable location. The portable resistance machine contains a housing, a pulley, a flywheel, a planetary gear assembly, an anchor, a retraction mechanism, and a pull cord. The housing contains a central gear support. The pulley, the flywheel, the planetary gear assembly, and the retraction mechanism are positioned within the housing. The central gear support is positioned within the housing. The planetary gear assembly is positioned within the central gear support. The pulley and the flywheel are axially connected opposite to each other along the planetary gear assembly. The retraction mechanism is operatively connected to the pulley, where the retraction mechanism is configured to retract the pull cord into a spooled state around the pulley. The anchor is externally connected to the housing.

A finger flicking football game comprises a waterproof triangular-shaped football for finger flicking and a pair of transportable game boards. Each game board comprises: a planar table surface having a plurality of apertures, each aperture designed to hold a cup sized for playing beer pong, and a pair of goal posts hinged from a rear end of each planar table surface. During game play, the players take turns flicking the football towards the cups in the other player's game board. Should their flicked football land in a cup, that player has scored a six point touchdown and can proceed to finger flick the football towards the other players goal posts for scoring an extra point.

A portable ball net post includes an adjustable base, and ball net lacing bars mounted on the base and adjustable in angle and height, wherein the base includes telescopic lacing bars and two support receptacles, both ends of each telescopic lacing bar are respectively connected to the support receptacles, a number of snap-fit fixing bases are installed surrounding the telescopic lacing bars by connection sleeves, and on each connection sleeve is provided a telescopic positioning assembly for controlling the stretching length of corresponding telescopic lacing bar; on the upper end surface of each snap-fit fixing base is provided net lacing bar clamping grooves for clamping the ball net lacing bars when retracted, on the lower end surface of each snap-fit fixing base are provided several racket clamping grooves, the ball net lacing bars are mounted on the support receptacles by a rotation positioning and angle adjusting structure and inside the support receptacle is provided a storage cavity.

A sports simulator calculates the rotational and translational velocity of a sports object. The rotational velocity is calculated using image analysis. The translational velocity is calculated using image analysis and a set of emitters and sensors. The simulator then computes the future trajectory of the sports object based on the rotational and translational velocity. In one embodiment, the sports object is a golf ball and the sports simulator simulates golf.
