A trampoline including: a frame including a plurality of frame segments/units connected together, each segment including lower and upper frame members secured together in spaced apart relationship for assembly with other like segments/units; a plurality of spaced apart flexible and resilient plates connected to the lower frame member of each segment/unit and extending upwards therefrom; a jumping mat extending between said plates and being operatively connected at or adjacent its periphery thereto, said plates engaging the upper frame member of each segment/unit respectively above the lower frame member of the respective segment and being arranged for movement inwards and outwards towards the opposite side of said mat and/or up and down in response to a user jumping on said mat, the plates having an upper portion preformed to have a bend in one direction and a lower portion preformed to have a bend in the opposite direction.

Described herein is a muscle trainer including a first and a second curved, elongate spring element, the two spring elements being arranged with their concave sides facing each other, having joint elements at their respective end areas and being connected to each other at their two end areas via joints formed from the joint elements. Also described herein is a method for producing such a muscle trainer.

An exercise machine is disclosed. The exercise machine comprises a tension generating device. The exercise machine comprises a translatable arm mount coupled to the tension generating device. The exercise machine comprises an arm coupled to the translatable arm mount. The exercise machine comprises a cable coupled to the tension generating device via the arm.

A hands and feet pull exerciser is disclosed which characteristically includes: a transverse frame tube; two pedals, set on the transverse frame tube with a spacing, and each pedal configured with an arc-shaped guard strip; two elastic pull tubes, including pulled sections and connecting sections, wherein the connecting section is winded on the transverse frame tube and located between the two pedals, and each elastic pull tube having a nose end; two loop portions, respectively configured on the pulled section; two handles, in the form of hollow tubes, sleeved on the loop portions of the pulled sections; an elastic sleeve, having a vertical through-hole and a transverse tube insertion hole, wherein the vertical through-hole trips the periphery of the connecting section, to elastically limit the connecting section; at least one limiting piece, fit inside at least one nose end of the elastic pull tube to achieve a fixing effect.

A fitness device comprises a waist belt configured to fit around a user's waist and at least one resilient leg loop member. The resilient leg loop member has a proximal end movably anchored to the waist belt at a posterior position. The resilient leg loop member has an opposite distal end configured for coupling with one of the user's feet. The fitness device causes a predetermined resistance force to be generated against the user's movement when the user extends the leg loop member beyond its length at rest. In some embodiments, two resilient leg loop members are provided. Methods of using the exercise device are also described.

A lightweight trampoline enclosure system has a bed subsystem and an enclosure subsystem. The enclosure subsystem comprises netting suspended from a plurality of flexible poles. Upon a jumper's impact into the surrounding enclosure subsystem, the energy of the jumper's impact is absorbed and distributed outward and away from the location of impact and into the trampoline bed subsystem.

A fitness hand-muscle developer to solve the defects of too strong elasticity, high cost and single purpose in conventional hand-muscle developers, which is suitable for the elderly, the weakling or women to exercise hand muscles in various ways. The fitness hand-muscle developer comprises a main body, elastic, rod-like, defining a lengthwise direction; a band, with two opposite free ends, fixed to the main body in the lengthwise direction of the main body; and a holding space, located between the band and the surface of the main body.

A weight collar for retaining a weight on a bar, comprising a bar engaging section having an opening for receiving the bar therethrough and a weight engaging section having proximal and distal ends, the weight engaging section extending from the bar engaging section so as to extend at least partially toward the weight when the bar engaging section receives the bar through the opening, the bar engaging section being configured to engage the bar with a gripping force as the weight exerts a rotational force on the distal end of the weight engaging section so as to prevent the weight from sliding off the bar, the distal end of the weight engaging section being orthogonally spaced at least 1 inch from a central axis of the opening, a center of gravity of the collar being orthogonally spaced at least 0.1 inches from the central axis toward the distal end.

A stationary jumping and trick bike is disclosed. An example device includes a frame assembly having a handlebar on a forward portion of the frame assembly and a seat on the frame assembly. A leg member including a leaf spring is connected to the frame assembly by a bracket having a plurality of ports selectable for pivotably attaching the leg member to the frame assembly to adjust pitch and/or angle of attachment of the leg member. A plurality of tensioners are connected between the leg member and the frame assembly. A foot rest is provided on the frame assembly. A standing and/or seated user holding the handlebar on the frame assembly can practice jumps and tricks by lifting and landing a lower portion of the leg member on a solid surface.

The present invention provides for an exercise apparatus comprising a pair of footplates arranged for reciprocal movement on respective supports, the supports extending outwardly from either side of a central frame portion of the apparatus, the footplates being arranged to receive a pair of human feet and so as to be moved by a user in a reciprocal manner in the direction of the supports as part of an exercise routine, and wherein the apparatus includes handgrip portions extending from the central frame portion of the apparatus, the handgrip portions being arranged for movement, such as for example upward and/or downward movement against a resilient bias during the exercise routine.
