A tandem sit-up device is provided. The tandem sit-up device has two support frameworks pivotably interconnected by a pivot bar so that the device moves between a flat, operable condition and a folded, storage condition. A distal end of the support framework may provide a seat portion. The pivot bar may provide an inner disc and outer disc rotatable relative to each other for moving between the operable and storage conditions. Each disc type provides a pair of arms for a proximal end of each support framework to selectively attach to so that a distance between the associated seat portion and a foot strap supported by the pair of arms.

The function of this invention is to provide exercisers with a safe and easy way to convert a legs-only exercising device, such as a stationary trainer or bicycle, with the capacity to exercise their upper and lower body muscle groups simultaneously or separately. This invention is portable and can be moved easily from one legs-only exercising device to another. Once they are mounted onto the handlebar or attachment bar of the legs-only device, it is now a full-body trainer. Exercisers mount the trainer, place their feet on the cycling pedals, place their elbows onto the elbow holders, grasp the hand grips, and now start their full body exercising activity. The degree of difficulty of their exercise trek is easily accommodated by allowing the rider to adjust the resistance for moving the forearm bars up and down for an upright bike, or back and forth for a recumbent trainer.

The presently disclosed subject matter is generally directed to a device for use in exercising and strengthening the body of a user, particularly the user's abdominal and core region. The device comprises a support member that is operably joined to a connector. The support member includes a main body that is planar in design, and a lip that includes one or more elements for providing a releasable pairing to the connector. The support member is positioned between two surfaces (such as a mattress and a box spring) to anchor the device in place. The connector secures a user's legs in position so that sit-ups or other exercises can be performed, e.g., while the user is sitting or lying in bed. The device therefore enables a wide variety of users to perform sit-ups and various other exercises with less effort and less stress on the body compared to prior art devices.

A wheeled exercise apparatus may include a single wheel, a central axle, a contoured body, a pair of handles, a pair of paddles and a clamping mechanism or torsion spring. A single wheel may have an interior cavity in the center with an opening on both sides of the wheel. A central axle may be housed inside of the interior cavity of the wheel. The contoured body may be connected to the central axle protruding from the sides of the wheel. The contoured body may further include two storage areas where may house and secure a pair of knee pads. The pair of handles may be connected to the contoured body's left and right sides. The pair of paddles may be attached on either side of the central axle. Each of the paddle may slide over the central axle and fastens through a clamping mechanism or a torsion spring.

A multi-axis adjustable exercise machine which is pivotable about both a pitch axis and a roll axis with respect to a base for allowing an exerciser to perform a wide range of exercises on a pitched or rolled exercise machine. The multi-axis adjustable exercise machine generally includes an exercise machine which is adjustable with respect to a base. The exercise machine may be pivoted about a roll axis to adjust the roll angle of the exercise machine or may be pivoted about a pitch axis to adjust the pitch angle of the exercise machine. One or more actuators may be connected between the base and the exercise machine to effectuate the pivoting of the exercise machine about either or both axes with respect to the base.

The invention is embodied in an exercise system that can allow its user to counterbalance the effects associated with a predominantly sedentary lifestyle though a fitness device that comprises a combination of (a) supporting the lower body in a manner that permits a user's upper body to act as a third class lever with the user's hips operating as fulcrum and (b) engaging in resistance exercises with the upper body in a horizontal position, unsupported above the greater trochanter.

A multi-functional sliding grip exercise device, specifically but not limited to: sliding grip medial pull-ups, sliding grip lateral pull-ups, lower back extension/sit-up assistance exercise. Exercise device will have rotatable rubber pegs attached to horizontal bars to aid in utility. Horizontal bars supporting hand grips will have apertures on its frame; apertures will take on the form of a “T” with arms going vertically down to engage device locking system. Horizontal bar with apertures will have tracks on top surface and bottom surface to support guidance of Hand grips. Horizontal bar with apertures will have a resistance element housed within, preferably but not limited to springs; also housed within bar will be spring caps with an protuberance attached that will make contact with Handgrips appendage to engage springs. Handgrips may have indentations to support lower back bar for lower back extension/sit-up assistance exercise. Device may have adjustable resistance.

A portable weight-based exercise system is disclosed that is capable of providing a user with a variety of weight-based exercise options. The exercise system includes a carrying case having a housing, containing dumbbells and a collection of weight disks for performing a variety of exercises, and a removable handle assembly for carrying or dragging the housing along the ground. First and second end bars and a center bar of the handle assembly are reconfigurable from a first configuration wherein they are disposed in a U-shaped arrangement to form the handle assembly to a second configuration wherein the first and second end bars are coaxial with the center bar to form a longer straight bar, which can then be combined with the dumbbells and collection of weight disks to form an assembled long weight bar. The housing may additionally include accessories such as a jump rope and an exercise band.

Disclosed is an exercise device having a platform and a roller. The platform has a surface sized and shaped to support a body part of a user and a pair of handles. The roller is coupled to the platform and configured to rotate relative to the platform. The platform is configured to translate in a first direction when the roller rotates in a first direction of rotation and translate in a second direction when the roller rotates in a second direction of rotation.

A sit-up board is provided comprising a non-slip backboard, a heel block on the backboard, and a foot strap in front of the heel block configured to hold a user's feet together and against both the heel block and the backboard during sit-ups.
