A portable ski accessory that converts a portable resistance device into a ski-type exercise machine is presented. The ski accessory contains a hanger chassis, a mounting element, a track, a cord, a handle, and a connection element. The hanger chassis contains a cord input portion and a cord output portion. The cord input portion is positioned terminally opposite to the cord output portion along the hanger chassis. The mounting element is connected adjacent to the hanger chassis. The track is positioned within the hanger chassis. The track traverses from the cord input portion to the cord output portion. The cord traverses through the track. The handle is connected to the cord. The connection element is connected to the cord, opposite to the handle.

An adjustably tensioned, transverse-suspended elastic element exercise device is disclosed. The transverse element is suspended between rigidly mounted frame or arm elements and sized so as to enable full range of motion exercises. The tension and height of the transverse elastic member can be adjusted to accommodate varying exercise levels and positions. The assembly may include handgrips and attachments to augment workouts. Electronic adjustability, metrics, programmability and Internet connectivity enhance the user experience. A method of using the device is also disclosed.

An improved yoga strap comprising at least two adjustable and locking buckles, one buckle at end of the improved yoga strap to create a loop at each end of the yoga strap, giving the improved yoga strap more utilitarian applications than a standard yoga strap. A second embodiment of an improved yoga strap has a center loop. A third embodiment has an elastic resistance band and clips.

A weightlifting assembly includes a wall mount bracket configured for mounting to a wall surface and a weightlifting rack assembly connected to the wall mount bracket. The weightlifting rack assembly may have various configurations, including a foldable weight rack assembly, a pull-up bar, a fixed weightlifting rack, a wall-mount weightlifting rack, or various other configurations. The wall mount bracket may be elongated along a lateral width thereof and may have a first mounting region and a second mounting region spaced from each other along the lateral width the wall mount bracket. The wall mount bracket may also include a central panel that is spaced from the wall surface to provide clearance for fasteners for connection to the weightlifting rack assembly, and in some embodiments, the weightlifting rack assembly may be connected to multiple wall mount panels.

Compact inertial device for muscle training, consisting of a pulling body (1) and a drive rope (2). The pulling body (1) in turn comprises a rotating main shaft (4), a reel (8) mounted on the main shaft (4), an inertia element (6) linked solidly to one end of the main shaft (4) for accumulation of kinetic energy from the rotation of the main shaft (4), and a planetary gear (5), which in turn comprises a central gear mounted on the main shaft (4), for multiplication of the transmission speed from the main shaft (4) driven by the reel (8) to the inertia element (6). In its preferred embodiment, the spool (8) is a conical spool with a smaller diameter sector to which one end of the rope (2) is solidly attached.

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.

An exercise machine is disclosed. The exercise machine comprises a pancake motor. The exercise machine comprises a torque controller coupled to the pancake motor. The exercise machine comprises a high resolution encoder coupled to the pancake motor.

An exercise machine may include a stationary frame, an inclinable portion movably connected to the stationary frame, and an incline mechanism connected to the stationary frame. The incline mechanism may include a coiling mechanism, a coiling rod of the coiling mechanism, a flexible coiling link movable with a rotation of the coiling rod, and where the flexible coiling link is connected to the inclinable portion.

A physical therapy device. At least one hexagon mount section is mounted onto a backing board. The hexagon mount section includes a plurality of hexagonal cutout sections. At least one peg holder is also mounted onto the backing board. A plurality of pegs is insertable into the peg holder and also into the hexagon mount sections. A board mount is also preferably connected to the backing board. Straps, strap attachment devices and bands may by draped over the board mount.

A physical therapy device. At least one mount section is mounted onto a vertical surface. The mount section includes a plurality of cutout sections. A strap attachment clip is connected to one of the cutout sections. A plurality of spacers is utilized to separate the mount section from the vertical surface. In a preferred embodiment the mount section is rectangular.
