An abdominal exercise roller with a powered wheel mechanism to assist the user during the abdominal exercise routine. The invention includes utilizing sensing technology and the electronic module to control the motor and optimize the performance of the abdominal roller during the exercise routine.

A pedaling exercise device includes a rotation mechanism configured to pivotally support a rotation shaft to allow rotation, a pair of cranks having first ends connected to both ends of the rotation shaft of the rotation mechanism, respectively, a pair of links having first ends rotatably connected to second ends of the cranks, respectively, and having second ends provided with wheels, respectively, a pair of pedal portions connected to the links along a longitudinal direction of the links, respectively, a rolling surface connected to a first end of the rotation mechanism on a user side, and a restriction portion configured to restrict separation of the wheels from the upper surface of the rolling surface in a case where the first end of the rotation mechanism is lifted such that the rotation mechanism is erected in a state where a second end of the rotation mechanism is grounded.

A pedal-driven exercise machine is designed for an exerciser in a seated position to do pedaling. The pedal-driven exercise machine is equipped with a main body portion, a crank unit that is rotatably supported by the main body portion, a pedal unit that is rotatably supported by the crank unit, and a foot space securing unit that secures a foot space at a foot of the exerciser by retreating the pedal unit from the foot of the exerciser when the pedal-driven exercise machine is out of use.

A ski exercising apparatus has a set of two parallel, arcuate rails, a wheeled carriage riding on the rails, a set of two articulated footpads mounted side-by-side on the wheeled carriage; and two sets of powerbands arranged parallel with a lengthwise centerline of the apparatus, spaced apart by at least one-half of the width of the apparatus.

An exercise machine with adjustable platforms for adjusting the angular orientation of one or more end platforms and/or carriage platform to allow for a wide range of exercise moves. The exercise machine includes a rail to which a carriage is movably connected and a first end platform connected to an end of the rail. The carriage includes a platform which may be adjusted between a level position in which the platform is laid flat and a raised position in which the platform is at an angular incline. The first end platform may similarly and independently be adjustable between the level position in which the first end platform is laid flat and a raised position in which the first end platform is at an angular incline. In some embodiments, the exercise machine may include a second end platform which is similarly adjustable between a level position and a raised position.

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 end platform for an exercise machine for increased support of an exerciser's spine, neck and head which allows for an expanded scope of exercises that cannot otherwise be performed on the machine without the improved platform. The end platform for an exercise machine generally includes a novel, ergonomically improved stationary platform affixed to at least one opposed end of a substantially longitudinal exercise machine that includes at least a resistance biased reciprocating platform. The improved end platform provides for increased support of exercisers' spine, neck and head, thereby allowing for an expanded scope of exercises that cannot otherwise be performed on the machine without the improved platform, and further provides for the attachment of new and novel exercise equipment accessories to the exercise machine.

An exercise machine handle system for providing a gripping structure that substantially surrounds a stationary or movable exercise platform. The exercise machine handle system generally includes a stationary or movable exercise platform and a perimeter handle surrounding the exercise platform. A space is formed between an outer edge of the exercise platform and an inner edge of the perimeter handle that allows a plurality of fingers of an exerciser to extend through.
