Methods and systems are presented in which one or more heavy-duty straps are positioned in contact with a top and bottom of a door and engaged with a heavy mechanism exerting a static tension greater than 10 newtons. A user can exercise using removable extenders attached to any of several loops at various vertical positions, creating enormous leverage along the strap(s). Supplemental cushioning may be utilized to minimize damage from large kinetic energy imbued upon components of the methods and systems during or after exercise.

A transformable exercise apparatus is disclosed. The exercise apparatus includes base arms parallel to each other, front legs and rear legs extending from the base arms. The exercise apparatus includes top arms, each connecting respective front and rear leg of each base arm. The exercise apparatus presents telescopic members stored in the front legs. The exercise apparatus includes a first table top and a second table top. The second table top includes collapsible legs. The collapsible legs fold and allow for placing the second table top and the first table top over the top arms, thereby transforming the exercise apparatus into a furniture. The second table top demounts and transforms into a workbench. The telescopic members extend and include a pull-up bar at the top, transforming the exercise apparatus into a pull up exercise apparatus. The apparatus may transfer into a leg press and arm press.

An exercise machine has a two-part hexagonal base. A plurality of supports is attached to the two-part hexagonal base, and a pair of intermediary elastics, each arranged by crossing one side extremity of the two-part hexagonal base from a top extremity of the exercise machine to the bottom face of the opposite extremity of the two-part hexagonal base. A top two-part bar is arranged horizontally between tops of the pair of intermediary elastics. A top cylindrical wheel arranged and centered on the top two-part bar, wherein the two-part hexagonal base having a set of cylindrical openings spaced along an entire length of the two-part hexagonal base, two side openings, two rollers, arranged transversally centered in a one of the two side openings, a bottom hollow arranged along the an entire length of the bottom of the two-part hexagonal base, two pairs of straight bottom bars arranged centered and spaced on and along the entire length of the bottom face of the two-part hexagonal base.

An elastic exercise band, including a main body, including a first section to receive a first portion of a body of a user thereon and resist at least partially deforming in response to an application of force thereto, and a second section disposed on at least a portion of the first section to receive a second portion of the body of the user thereon and resist at least partially deforming in response to the application of force thereto, and a plurality of surface linings disposed on at least a portion of the first section and the second section to prevent the first section and the second section from sliding away from the body of the user during exercise.

A core training apparatus for the golf swing. A semicircular member is coupled with a support member, and a resistance member is connected to one of the coupling points. The resistance member is secured to a fixed point, and the user rotates the apparatus back and forth with the user standing at the center rotational axis of the semicircular member, with the resistance member being guided along the semicircular member. The back-and-forth rotation acts to increase and decrease tension on the resistance member thereby exercising the core of the user.

An exercise machine comprises an arm support, including: a carriage configured to slide within a track attached to the exercise machine; and a support assembly that floats the carriage relative to the track, wherein the support assembly is disengaged by the application of force via the arm. An exercise machine comprises a rotatable column, wherein the column supports an arm, and a gear detent mechanism to support a discrete number of positions for the rotatable column. An exercise machine comprises a tiltable arm, and a mechanism to support a discrete number of positions for the tiltable arm.

An apparatus is provided for use in resistance training. The apparatus may include a bar with pulley hubs on its ends. The apparatus may further include two slings, each including connectors and a rigid, straight or arc-shaped bar. The slings may be suspended from the pulley hubs and support an elastic band, which may provide resistance during exercise. A footplate may also be provided to hold part of the band to the floor during use.

A low friction rehabilitation board having an integral band retaining feature is described. The rehabilitation board may have a coefficient of static friction of no more than about 0.5 and in some embodiments no more than about 0.06. The rehabilitation board has a plurality of band retaining feature configured along one or both ends and may be an integral band retaining features being formed in the board. Additionally, the rehabilitation may include one or more band retaining features on one or both sides of the board. The unique configuration of the band retaining features enables rehabilitation method heretofore not possible with a single board. Resistance bands may be retained in the band retaining features and coupled to a user's limb, such as a foot or ankle, to resist motion, such as sliding or extending the foot along the low friction surface of the rehabilitation board.

Described herein are methods of manufacturing multi-use mounting brackets having an extension with an internal support rod configured to support gym accessories. A single multi-use mounting bracket fits gym rigging or gym racks of different sizes and hole configurations. This accomplished by including multiple pairs of holes that are sized and positioned to be compatible with different gym rigging configurations. The multi-use mounting brackets described herein are advantageously designed to resist both downward and upward forces.

A workout device that allows for at home Nordic hamstring curls using a. doorframe or other immovable object is disclosed.
