The present disclosure is directed to climbing wall assemblies having a variety of improvements. For instance, the climbing wall assemblies may include connectors to attach the surface panels to the framework, in which the connectors may be mounted substantially anywhere along the front of the framework and at substantially any angle, providing for the securement of climbing panels in various geometries. The climbing wall assemblies may also include braces that may easily be adjusted to a desired length and configuration during construction of a climbing wall. The climbing wall assemblies may also include variable-angle, integral front posts, which provide for the easy and stable securement of climbing panels in various geometries. These improvements provide climbing wall assemblies that may be easily assembled to produce a desirable climbing wall structure having few framework components.

An electric treadmill includes a motor and a motor driving circuit. The motor driving circuit is operable to control electric current flow from a positive electrode through the motor to a negative electrode to drive the motor. The motor driving circuit has a switch path connected between the positive electrode and the negative electrode. The switch path has a resistance element and a switch element connected in series. When the motor driving circuit receives power from the external power source, the switch element will automatically switch to an open state so that the resistance element is inactive; and when the motor driving circuit does not receive power from the external power source, the switch element will automatically switch to an closed state so that the resistance element is operated to provide a resistive load for stopping rotation of the endless belt.

The bicycle ramp of the present invention is foldable and easily transportable. The bicycle ramp of the present invention may be built directly onto a utility trailer with a foldable gate and wheels and thus is transportable to be pulled along the back of a suitable vehicle using the hitch. The bicycle ramp of the present invention creates an inclined surface for bicycle riding applications, including the teaching of a beginning cyclist skills such as balancing and pedal. There is a receiving slot to engage the rear wheel of the bicycle at the flat upper section of the bicycle ramp. The receiving slot stabilizes the bicycle in a static position until a releasable stopper is released to launch the rider down the angled sections of the bicycle ramp.

A protective rowing device for compression of the abdomen is provided that comprises a brace and U-shaped support member that may connect to a rowing machine seat and rail.

Sports equipment and/or areas of play are provided, comprising a sports equipment or area of play and a sensor.

An exercise machine can include sensors to detect objects proximate to and/or moving towards the exercise machine. For example, a treadmill, or a control system associated with the treadmill, can determine an object is moving towards or is already proximate to a deck of the treadmill (e.g., a front area, middle area, or rear area of the deck of the treadmill) and modify operations of the treadmill in response to the determined or detected object or object movement. The treadmill can utilize various detection mechanisms when determining an object is within a proximity to the treadmill, such as time-of-flight (ToF) sensors or cameras, millimeter wave (mmWave) sensors, computer vision (CV) technology, and so on, to detect the proximity of the object (or movement of the object).

A floatation device is provided. In some embodiments, a floatation device is provided, comprising an inflatable ring composed of a transparent material, wherein the inflatable ring includes: an outer air chamber having a first valve for inflating the outer air chamber; an inner air chamber having a second valve for inflating the inner air chamber, wherein the outer air chamber and the inner air chamber are not in communication; a cut through the outer air chamber and the inner air chamber of the inflatable ring that forms opposing ends of the inflatable ring; and a plurality of fasteners placed on a top surface and a bottom surface of the outer or inner air chamber for detachably connecting the opposing ends of the inflatable ring.

An adjustable weight kettlebell includes a body defining an internal cavity configured to receive one or more of a plurality of weights, and a weight selector assembly configured to selectively couple one or more of the plurality of weights to the body. The weight selector assembly may include an actuator to enable a user to select one of a plurality of available weight settings. The weight selector assembly may be locked for adjustment when the kettlebell is removed from a support surface such as a base, thereby inhibiting inadvertent detachment of the weights from the kettlebell during exercise. The weight selector assembly may automatically shift to the closest weight settings upon release of the actuator and may automatically unlock upon placement of the kettlebell on the support surface such as the base, the bottom weight if not coupled to the kettlebell, or any other suitable support surface.

An adjustable ab wheel has a main shaft and two wheels mounted on the main shaft. The main shaft has two external threaded sections. Each one of the two external threaded sections has a thread direction opposite to the thread direction of the other one of the two external threaded sections. Each one of the two wheels has a threaded hole axially defined through the wheel and mounted with a respective one of the two external threaded sections. When a user rolls the two wheels forward, the two wheels approach each other and abut against each other. Abutment between the two wheels allows the two wheels to brake themselves, so that the adjustable ab wheel can prevent users from over rolling the two wheels forward and suddenly falling down to the floor.
