An ankle exerciser for exercising a user's ankles and includes a base, two pedals and two rotary units. The pedals and the rotary units are installed to the base. The rotary units are located between the base and the pedals so as to allow the pedals to be pivoted in multiple directions so as to stretch the ankles, and to keep ankles healthy.

An exercise apparatus includes a rope wrapped around a spindle having a one-way clutch rotatably mounted on a driveshaft. The driveshaft is driven by a motor controlled by a motor controller. The controller is capable of driving and braking the motor such that the driving torque and the braking torque can be set at different values to ensure the safety of the apparatus and user.

A treadmill is provided according to various embodiments herein. The treadmill includes a frame; a front shaft coupled to the frame; a rear shaft coupled to the frame; and a running belt disposed about the front and rear shafts, wherein the running belt assumes at least a portion of a curved running surface, the curved running surface having a radius of curvature of approximately 88 to 138 inches.

An exercise device consisting of a housing having a rope extending therethrough and wherein the rope is wound about a spool mounted on a driveshaft driven in a forward direction by a motor. The spool includes a one-way clutch for engaging the driveshaft in the forward direction and freely rotating on the driveshaft in the reverse direction. A recoil mechanism is coupled to the spool to rotate the spool in the reverse direction and rewind the rope.

A balance board system, comprising, a rotatable roller, a balance board having a lower surface that sits atop the rotatable roller and reciprocally rides on the rotatable roller, the balance board lower surface having a plurality of attachment points, a plurality of board connectors disposed at the plurality of attachment points, a plurality of stop connectors and a plurality of roller stops coupled to at least two of the plurality of stop connectors, the plurality of roller stops are attachable to the balance board at a respective one of the plurality of attachment points.

A cordless treadmill including a frame, a belt system, and a drop-in cartridge is disclosed. The cartridge includes a plurality of staggered rollers configured to provide tactile feedback to the user. The frame is adapted to receive the belt system and the cartridge as they are lowered into the frame, and the frame is adapted to place the belt of the belt system into tension as the belt system is lowered into the frame. An integrated flywheel generator system provides smooth operation of the treadmill and generates electricity to power additional systems.

The present invention discloses a stable basin-shaped trampoline, which includes a frame, multiple resiliently flexible rods with lower ends and top ends respectively, and a bouncing mat; the lower end of each rod is inserted into the frame, and the bouncing mat is bridged arranged above the top ends of the rods; the outer diameter of the bouncing mat is less than that of the frame, the frame, the resiliently flexible rods and the mat encloses into an inverted basin-shaped structure with a relatively larger lower part and a small upper part; or, the outer diameter of the bouncing mat is larger than that of the frame, the frame, the resiliently flexible rods and the bouncing mat encloses into a basin-shaped structure with a large upper part and a small lower part. The basin-shaped structure increases the stability of the trampoline and makes the trampoline not easy to flip.

An information related to the position of an actuator coupled to a cable which is coupled to a motor is received. A filter is used to provide an input to a motor controller coupled to the motor, to adjust torque on the motor such that a strength curve is implemented relative to the position of the actuator.

An exercise machine is described that incorporates a double retractable resistance band system for rowing exercises and that includes a multi-purpose, morphable swinging seat assembly that applies to convertible exercise machines and rowing boats. The double retractable rowing system is detachably integrated into a base plate (inclined planar board) of the exercise machine. The base plate consists of a platform set at an angle consistent with the foot-placements of sit-down rowing machines and rowing shells together with an integral set of quick-release slots located above and to the outside of the toes of the foot placement positions. The multi-purpose, morphable swinging seat assembly provides an improved method/structural assembly for seat-based rowing machines, convertible/multi-purpose exercise machines and an improved architecture for boat-based rowing systems.
