A trampoline has a horizontal bed frame. A bed is suspended across the horizontal bed frame. The horizontal frame includes a horizontally oriented bed frame for suspending the bed. Frame legs are attached to the horizontal frame for supporting the horizontal frame above a ground surface. An enclosure includes a net suspended from an upper enclosure loop. An enclosure frame includes enclosure poles formed as right oriented spiral section members and left oriented spiral section members preferably made from metal tubing such as steel tubing. The enclosure poles are diagonally oriented. The right oriented spiral section members intersect and are connected to the left oriented spiral section members at intermediate junctions to form X-shaped panels, namely a first X-shaped panel, a second. X-shaped panel and a third. X-shaped panel. At least three panels are used based upon the diameter of the enclosure frame.

A hitting extension for a body-positioning trainer is disclosed. The hitting extension has an elongate, generally flat body with first and second ends spaced from one another. The second end terminates in a rounded distal edge. A first opening formed in the body proximate to the first end allows the hitting extension to be connected to the body-positioning trainer. The body-positioning trainer restricts the movement of the arms in order to allow the user to focus on torso movement, and the hitting extension allows the user to hit a ball, or another such projectile, using the trainer. Methods for training a user in torso movement using the hitting extension are also disclosed.

Provided herein are embodiments of a barbell spotting apparatus having all the benefits of a free-floating, unconstrained barbell in both the horizontal and vertical axes with the safety of a dedicated spotting mechanism, while addressing safety, noise, and space concerns raised by typical barbell apparatus. The embodiments herein permit a loaded barbell to be positioned in line with the axis of motion of the lift to be performed at both the beginning and end of the lift.

A trick scooter comprising a base plate, a support member, comprising a first end and a second end, a handle, comprising a first end and a second end, wherein the handle is attached to the second end of the support member. Furthermore, the base plate is manufactured of elastic and flexible material. Such a trick scooter is advantageous as it is lightweight, easy and safe to handle and does not damage the surroundings or cause injury to people nearby.

An interchangeable finger insert system for a bowling ball is provided. An inner sleeve has a cylindrical opening defined at a top end. A base encloses a bottom end of the inner sleeve. A fastener-head feature is defined in the base and accessible through the cylindrical opening. An engagement feature is formed along an exterior surface and configured to allow the inner sleeve to be rotationally inserted into an internal bore. A fastening tool with an elongated shaft and a locking feature defined at a distal end of the shaft is provided. The locking feature shaped to engage the fastener-head feature defined on the inner sleeve. The locking feature of the fastening tool engages the fastener-head feature on the inner sleeve, and rotation of the fastening tool is configured to rotate the inner sleeve into the internal bore thereby locking the inner sleeve in the bowling ball.

Embodiments of the invention provide a plurality of support bars that may be fitted to the corner of a trampoline frame to provide increased stiffness for the trampoline frame. The support bars may be placed over or in the vicinity of the trampoline's legs to create a zone of increased stiffness. The support bars may also serve as an entry point to the trampoline such that the trampoline user need not stand on the trampoline's suspension system (e.g., helical springs) in order to enter the trampoline. The user may be protected from the support bars by the use of an edge pad filled with an energy absorbing material.

A method for controlling a control interface of an exercise machine during the enjoy of a multimedia content includes providing a multimedia content of a personal trainer preparatory to performing a set workout program on the exercise machine, usable through the control interface; associating configuration instructions of the exercise machine with the multimedia content readable by a data processing unit of the exercise machine, synchronized with playing of the multimedia content; during the enjoy of the multimedia content, if a playing time instant falls within a set time interval provided by the configuration instructions, dynamically modifying the control interface of the exercise machine so that it assumes a respective operating configuration corresponding to the set time interval reached by the multimedia content, in the respective operating configuration, showing the user on a display module, temporary controls usable through the control interface; and setting the exercise machine based on the temporary controls.

Techniques for strength training using an exercise system including an electric linear motor. The exercise system includes a stand, including the electric linear motor comprising a mover and a rotor, and a user interface. The exercise system further includes an exercise attachment coupled to the mover in the electric linear motor, and a controller configured to control force generated by the electric linear motor, where an amount of force required to move the exercise attachment changes based on the force generated by the electric linear motor, and configured to display information related to moving the exercise attachment.

Provided herein is a hoop spring assembly for use in a mat connection system of a trampoline, in which the hoop spring assembly includes a pair of hoop portions hingedly connected by a pair of laterally positioned hinge members and a resilient member, such as an elastic band or coil spring, operably connected to each of the hinge members and extending therebetween. Mat connection systems and trampolines including such a hoop spring assembly are also provided.

A moveable rack mount apparatus for use with an exercise rack constructed of at least one rack tube configured with at least one rack hole, comprising: a tube passage sized and shaped for slidable passage therethrough of the rack tube; a reversible locking mechanism configured to engage the at least one rack hole of the rack tube when the rack tube is in the tube passage; at least one attachment hole for securing at least one of a plurality of interchangeable exercise-related attachments to the moveable rack mount apparatus.
