A removable stretchable cover for exercise equipment has a first wall, a second wall, two side walls and two end walls arranged to form an interior cavity and an opening through which the exercise equipment is appointed to traverse. The opening is formed as a stretchable slit opening adapted to expand to engulf the exercise equipment, and contract in a closed configuration when the exercise equipment is housed within the interior cavity to substantially enclose the equipment within the cover. At least one anti-slip surface is integrated within at least one of the first wall, second wall, two side walls or two end walls. The cover is composed of a thin, stretchy, soft material so that it can be significantly stretched and contracted to snuggly fit over the exercise equipment. Examples of exercise equipment for which the cover is especially well suited include yoga blocks, foam rollers, exercise balls and arm handles of exercise machines.

A fitness device contains a strap, a handle, and a plate. The strap is substantially inelastic and flexible. The plate is substantially rigid. The handle at least partially envelopes the strap. A method of exercising with such a fitness device is also described herein. Other fitness devices and other methods of use are also described herein.

A portable strength training apparatus, system and method. The apparatus can include a platform base having a top surface, a bottom surface, and a plurality of base attachment mechanisms. One or more of the plurality of base attachment mechanisms can be removably coupled to a resistance band. A force sensor can be coupled to the resistance band, the force sensor comprising a force transducer that can include electronic circuitry to track, record, and analyze resistance forces applied to the resistance band.

There is provided a plank exercise device including a support portion adapted to receive arms or hands of a person and adapted to receive a display device, a destabilizer connected to the support portion, and a stationary base adapted to hold the destabilizer.

An exercise machine with resistance selector system for selecting the number of bias members applying a resistance force against a movable platform. The exercise machine with resistance selector system generally includes one or more switches which are connected to the movable platform. Each of the one or more switches is adapted to engage or disengage a corresponding latch. When engaged, the latch will connect a corresponding bias member to the movable platform. When disengaged, the latch will disconnect a corresponding bias member from the movable platform. In this manner, an exerciser may easily adjust the number of bias members connected to the movable platform so as to adjust the resistance force applied against movement of the movable platform along a rail.

An exercise machine for working core muscles includes a base, a handle bar connected to the base, and a leg support assembly connected to the base and extending substantially horizontally in a direction away from the handle bar. When one of the handle bar and leg support assembly is swung in a clockwise direction, the other of the handle bar and leg support assembly is swung in a counterclockwise direction, and when the one of handle bar and leg support assembly is swung in a counterclockwise direction, the other of the handle bar and leg support assembly is swung in a clockwise direction. The opposite direction rotations of the handle bar and leg support assembly create a double twist motion in the core muscles of a user of the machine.

According to various embodiments, there is provided a plank exercise device including a support portion adapted to receive arms or hands of a person and adapted to receive a display device, a destabilizer connected to the support portion, and a stationary base adapted to hold the destabilizer.

A multi functional exercise apparatus used for resistance training. An electric digital scale platform will be applied for the user to exercise with resistance bands and determine the resistance in units of pounds or kilograms.

In one aspect, an active exercise chair comprising seat support, wherein the seat support is rigidly affixed to a top section of a shaft of the gas spring; a seat, wherein the seat is connected to the seat support; a seatback support, wherein the seatback support is pivotably connected to the seat support about a discrete pivot point; a seatback carriage, wherein the seatback carriage is slidably connected to the seatback support, wherein the seatback carriage is connected to a seatback, and wherein the seatback traverses a translational path defined by the geometry of the seatback carriage and the seatback support.

A device or system including an assessment device with a body with a top surface ruled with a pattern to or instruct students in their parts during a physical position or movement between different positions, such as may be learned in a class or virtual class. The rulings include vertical lines and horizontal lines at various spaces, spacings, and intersections.
