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.

Disclosed is an ice hockey ball-controlling skill training device, which comprises a plurality of cross members hinged end to end, and the connecting ends of adjacent two cross members are provided with fixing components for connecting and fixing; the training device also compromises a ball, LED lighting components, and induction components, the induction component compromises a plurality of Hall elements and electromagnetic induction elements, a plurality of Hall elements are respectively arranged on a plurality of cross members, the electromagnetic induction elements are arranged in the ball; when the ball passes under the cross member, the electromagnetic induction elements can triggers induction with Hall elements. During the training process, when the ball passes under the cross member, the electromagnetic induction element can trigger induction with the Hall element. Compared with the ball control device in the prior art, the device has more accurate induction.

A FEPS (flexion extension pronation supination) device includes: a structural frame; a shaft mounted to rotate relative to the structure frame; and a brake that is structured to apply a selectively variable resistance against rotation of the shaft relative to the structural frame. A FEPS (flexion extension pronation supination) device includes: a structural frame; a shaft mounted to rotate relative to the structure frame; and a gripping member mounted to the structural frame and structured to adhere to an external support surface. A method includes operating the FEPS device by rotating the shaft.

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.

A dual layer mouthguard with a U-shape polycarbonate/EVA skeletal base includes channels and ramps to ensure a uniform thickness on the occlusal, buccal and lingual surfaces of the teeth for proper alignment of the jaw and positioning for protection during the placement of the mouthguard. The liner is softer than the base when introduced to heat and remains softer as it is cooled. The base may also include metal/magnetic insertion to serve as a tethering device for temporary storage.

A resistance sensing mechanism including a resistance adjusting unit including a holder frame, a locating sleeve disposed above the holder frame, an adjustment screw rod rotatably inserted through the locating sleeve and a screw nut threaded onto the adjustment screw rod and pivotally connected to the holder frame, and a sensor unit including a first linkage pivotally connected with one end to the screw nut, a second linkage having one end pivotally connected to an opposite end of the first linkage and an opposite end pivotally connected to the locating sleeve, a sensor mounted at one of the first and second linkages and a sensible member mounted at the other of the first and second linkages to face toward the sensor. Subject to the linkage relationship between the first and second linkages, the distance between the sensor and the sensible member can be changed, thereby generating a relative sensing signal.

A putting training apparatus is a putting training aid for teaching the accuracy of aim when putting in the game of golf. A rectangularly shaped elongated planar member, which has a flat top surface with markings that guide the user to hit the ball with a putter along a straight trajectory and into a putting cup in the elongated planar member at the opposite end from the putting end. An attachable guide having a marker attaches to the putter that the user attempts to keep placed above an offset straight line helping the stroke to move along the straight path.

A countercurrent swimming system for swimming pools or swimming baths comprises a housing box which has at least one water inlet opening and at least one water outlet opening, a propeller for generating a water flow, which propeller is arranged in a flow channel, the flow channel opening into the at least one water outlet opening downstream of the propeller and hydraulically communicating with the at least one water inlet opening upstream of the propeller, a drive motor for the propeller. The countercurrent swimming system includes the drive motor arranged outside of the housing box and in that the propeller and the drive motor are coupled to one another via a magnetic coupling.

A swing training system includes a base unit having a grapple that is movable between open and closed positions. A free end of an elongated swing device, such as a golf club or a hockey stick, is secured within the grapple. The swing device is manipulated to exert a force on the grapple and a load cell, away from the base unit, for a predetermined value, such as force and/or time. Relative movement between the grapple and the base is substantially limited while the swing device is manipulated. Once the predetermined value is attained, the grapple releases the free end of the swing device.

A sports and games apparatus consisting of two rods and an aerodynamic projectile with an opening which receives the two rods. The projectile is launched by manipulating the rods in an opposing fashion. The opening of the projectile is of the appropriate size to allow for the rods to slide through, but not large enough that the projectile exhibits unwanted motions that inhibit accuracy during the launching motion. The rods are used to propel the projectile towards a variety of targets which interact with the projectile in various ways. The projectile may comprise a multitude of aerodynamic shapes and a multitude of methods for interacting with targets.
