A reformer may include a frame extending between a first end portion and a second end portion. The reformer may also include a carriage slidably coupled to the frame, where the carriage is movable along a length of the frame. The carriage is configured to be selectively and releasably coupled to the first end portion of the frame, and selectively and releasably coupled to the second end portion of the frame.

An exercise system that may be rail-less, frameless, and/or portable is described. The exercise system includes a carriage having a plurality of wheels and a stationary platform. The stationary platform is independent of and separate from the carriage, and the stationary platform is freestanding. At least one tension member having a first end is attached to the carriage and a second end is detachably attached to the platform such that the carriage is movable on a horizontal plane parallel to a ground surface while the stationary platform remains in a fixed position.

A reversible resistance exercise machine for reversing the direction of applied resistance against a movable platform of an exercising machine. The exercise machine has a frame, a carriage movably positioned upon the frame, and a plurality of biasing members. A plurality of first tension connectors are accessible near the first end of the carriage and are adapted for removably attaching selected biasing members near the first end of the carriage to resist motion of the carriage in the first direction. A plurality of second tension connectors are accessible near the second end of the carriage and are adapted for removably attaching selected biasing members near the second end of the carriage to resist motion of the carriage in the second direction. A user selectable amount of force may be applied to the carriage to resist movement in either of the first direction and the second direction.

A running device and method of using the device are disclosed. The device may include a moveable material within an inner chamber of the running device's housing. In operation, a running device may be held in each hand and the runner may thrust both hands downward prior to landing and quickly bring the devices to a vertical stop after landing. Bringing the devices to a vertical stop may cause the moveable material to collide with the housing and increase the force exerted by the runner on the ground. A delay component may delay the peak force exerted by the material against the housing so that the translation of that force to the ground coincides with the peak force that the runner would have exerted against the ground in the absence of the devices.

In an example, a bed exercise system includes a foot pad and first and second elastic connectors. The foot pad includes a rigid support member. The first elastic connector has a first end coupled to a first lateral side of the foot pad and a second end for coupling to a support structure. The second elastic connector has a first end coupled to a second lateral side of the foot pad and a second end coupling to the support structure. When the second ends of the first and second elastic connectors are coupled to the support structure: (i) the foot pad is movable between a first position and a second position relative to the support structure, and (ii) a tension on the first elastic connector and a tension on the second elastic connector increases as the foot pad moves from the first position to the second position.

A portable single bicep exercising machine is disclosed. The machine may comprise articulable framework running about a length of a user's given arm. This framework may be divided into upper framework and lower framework, with an articulable fulcrum connecting the upper framework to the lower framework. In use the upper framework, at an under arm pad, may be retained in a user's should/armpit region; while the lower framework may comprise a handle to be engaged by the user's hand of that same arm. Also between this upper framework and this lower framework may be one or more tension means, such that when the handle is articulated towards the under arm pad, about the fulcrum, that articulation is through resistance. It is such resistance that exercises the bicep of that same given arm.

An exercise machine rail indicia system for providing indicia to improve exercise instruction. The exercise machine rail indicia system generally includes a frame a rail, a carriage movably positioned upon the rail, a bias member connected between the carriage and the frame that applies a bias force upon the carriage, a first position indicator positioned upon the upper surface of the rail, and a second position indicator positioned upon the upper surface of the rail. The first position indicator and the second position indicator are distally spaced apart a first distance. The first position indicator and the second position indicator visually indicate to the exerciser where to position the carriage along the first rail during the performance of an exercise.

Implementations of squat machines may include a seat coupled to a platform, a first foot brace directly coupled to the platform, a second foot brace directly coupled to the platform, a knee brace post coupled to and extending perpendicularly away from a first surface of the platform, a knee brace arm directly coupled to the knee brace post and extending perpendicularly away from a longest length of the knee brace post, and a knee brace directly coupled to the knee brace arm. The knee brace may be configured to contact the front of either a user's knees or shins while performing a squat exercise. The seat may be configured to temporarily contact a buttocks of a user while performing the squat exercise.

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.

An exercise machine support system for providing increased versatility including inclination or declination of an exercise surface, a reduction in the overall length and width of the exercise machine, and an enhanced user interface which reduces the risk of injury. The exercise machine support system generally includes a cantilevered exercise machine which is adapted to have a variable angle of incline or decline with respect to a horizontal ground surface. The exercise machine will generally include a base and a support which extends between the base and the exercise machine. The upper end of the support is connected to the exercise machine by a first pivot such that the exercise machine pivots about the support. An adjustment device may be utilized to pivot the exercise machine and thus adjust its angle of incline. Various types of adjustment devices are disclosed, including an actuator, ratchet-and-pawl, gears, and cam.
