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.

A shoulder part cart for storing football shoulder pads. The shoulder pad cart has a flat cart base with multiple upright posts. Each upright has a shoulder support located on the upright. The shoulder support has a flat resting surface where the under side of the shoulder pad rests. The shoulder support is bent to have a slight curve to mirror the slight bend of the shoulder pad allowing the shoulder pad to remain up right. Each shoulder support has a spacer on the front and rear side to keep the shoulder pads. The spacers keep the shoulder pad in its shaped form. The uprights are mounted to the base using a mounting panel and bolts.

A VR (virtual reality) omni-directional exercise machine with a terrain environment simulation function is provided. The VR omni-directional exercise machine includes a protective ring, a protective ring supporting rod, a protective ring supporting column, an exercise platform, a control machine, and VR head-mounted display, wherein the protective ring is arranged above the exercise platform and is connected to the protective ring supporting column through the protective ring supporting rod, and the bottom of the protective ring supporting column is fixedly connected to the outer side of the exercise platform; a moving vertical rod module lattice is arranged in the exercise platform, the moving vertical rod module lattice and the VR head-mounted display are both connected to the control machine, and the control machine is used to coordinate and control the movement of the moving vertical rod module lattice according to an terrain environment displayed in the VR head-mounted display.

A motorized treadmill includes a base, an endless belt movable relative to the base for allowing a user to exercise thereon, a motor coupled to the endless belt for driving the endless belt to rotate, a current sensor coupled to the motor, and a controller in communication with the motor and the current sensor. The current sensor is configured to detect a motor current of the motor when using the motorized treadmill. The controller is configured to analyze fluctuations of the motor current to determine whether objects or children interfere with rotation of the endless belt. When the current sensor detects a current change does not associated with the user of the motorized treadmill, the controller determines that the endless belt is interfered by objects or children and stops operation of the motor to slow or stop rotation of the endless belt.

A yoga towel is for use in conjunction with a suitable mat or converter that allows an existing mat to be retrofitted to be used with the present yoga towel. The yoga towel has one or more magnets and/or metal attached, advantageously to its perimeter and/or with a center portion of the towel. A suitable surface such as a yoga mat will have a complementary metal and/or magnet so that when the yoga towel is placed on the yoga mat, the yoga towel through magnetic forces (i.e. attraction) is held in place. Advantageously, in one form, the magnets and/or metal are strips in the yoga towel and/or yoga mat are in the form of flexible strips of magnetic material and/or metal.

An exercise machine comprises a motor. The exercise machine comprises a lockable translatable mount. The exercise machine comprises a cable coupled to the motor via the lockable translatable mount. The exercise machine comprises a sensor coupled to the lockable translatable mount. The sensor is used at least in part to determine mount lock state.

The ball-projecting batting tee comprises a support base, a support column, and a remote control. The ball-projecting batting tee may be a batting practice aid that may be placed on top of home plate and may pneumatically project a ball upwards from the top of the support column to simulate a pitch. The ball-projecting batting tee may be adapted to project the ball upwards under the control of a coach using the remote control. As non-limiting examples, the ball may be a baseball or a whiffle ball. A directional cover located at the top of the support column may pivot to direct the ball towards first base or towards third base to simulate outside and inside pitches.

Disclosed herein are robust disposable alternating tangential flow (ATF) housing and diaphragm pump units and associated methods of manufacturing, testing, wetting, and using the same.
