An easily assembled and disassembled frame for a net game includes a rigid multi-part frame with a cross-member that is non-sagging. Sections of the multi-part frame have an elliptical profile. A net stabilizer includes a tensioning member coupled at one end to a retention member of the frame, and having the other end of the tensioning member inserted into a center sleeve of the net, and, a center sleeve with a securing member for fastening securely at one end to the cross-member.

A portable net system for net games is disclosed which provides for rapid assembly, lightweight construction, durability against damage while assembling and playing, and also provides enhancements inherent in the design which allow for improved marketing and advertising during tournaments. The net functions through having a bow-shaped tensioning rod reacting against the net top-tape to provide primary shape, net tension and height control. A vertical post at each distal end is attached to the foldable feet to provide lateral stability, and these are attached to the net via insertion into the net end-band and durably connected via the rigid bow end-connectors. Removable end-panels at each end net termination provides for a self-tensioned surface where advertising and sponsor labels may be attached.

A training device for tennis provides multiple training stations for various tennis strokes.

A swing trainer comprises a wire rope onto which are positioned a plurality of balls, each having a hole through the center, and cushioning devices on either end of the wire rope. The balls and cushioning devices can freely travel along the length of the wire rope. The rope is anchored to an immovable object or held on one end by a user.

An interchangeable ground mount system comprises (a) a ground mount, (b) at least one post segment, and (c) an interchangeable head. A variety of interchangeable heads can be mounted to one or more post segments, which are inserted into a semi-permanently installed ground mount, typically for lawn and garden use.

Provided is a net system comprising a frame, a first and second vertical riser each connected to opposite sides of the frame, a top cord connected to the distal end of each vertical riser, a bottom cord connected to a proximal end of each vertical riser, and a net suspended by the top cord. The top cord and bottom cord are balanced in tension by the flexible vertical risers. When the proximal end of the vertical riser is urged towards the center of the net, by action of a hinge between proximal and distal ends of each vertical riser, the distal end of the vertical riser is moved outward, thus tensioning the top cord.

A portable exercise apparatus intended for indoor use. A vertical spine is constructed and mounted to a plurality of wall braces. The spine has a series of pairs of hooks aligned vertically. The user can then place either a pulley plate or a body into a desired hook. Hooks are configured such that when the pulley plate or body is placed therein, force in a downward or straight direction would not remove the pulley plate or body. A bench can be attached to the pulley plate or body which then allows a user to set or lie on and perform exercises using a resistance cord which can be connected to the body, pulley plate, and or braces.
