A step exercise apparatus with a self-centering pedal system. The system comprising a frame and a seat supported from the frame. A first pedal assembly and a second pedal assembly are pivotally supported from the frame positioned so as to be manipulable by a user seated in the seat. A linkage is positioned in communication with the first pedal assembly and the second pedal assembly such that movement of either pedal assembly in a first direction causes movement of the other pedal assembly in a second direction opposite of the first direction. A brake is preferably employed for resisting motion of the first pedal assembly and the second pedal assembly in at least the first direction. A centering system positions the first and second pedal assemblies in a substantially central position when not being manipulated by the user.

In various embodiments, an apparatus for exercising can include a housing, a first inner tube, a second inner tube, and a compression spring operable to resist motion when compressed. The first inner tube is coupled with a first end of the compression spring and the second inner tube is coupled with a second end of the compression spring. In addition, the apparatus can also include an extension spring inside the housing. Furthermore, a portion of the compression spring and a portion of each of the first and second inner tubes are inside the housing. Note that a first end of the extension spring is coupled with a first handle or loop and the second end of the extension spring is coupled with a second handle or loop. The extension spring is operable to provide resistance during pulling motion away from center of the apparatus.

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.

An exercise machine carriage handle system for providing handles for an exerciser to grasp with their hands thereby expanding the type of exercises that may be performed. The exercise machine carriage handle system generally includes a frame having a track, a carriage movably connected to the track, a bias member connected between the frame and the carriage, a first handle connected to the carriage near the first side, and a second handle connected to the carriage near the second side. The first handle and second handle are adapted for grasping with a first hand and a second hand respectively of a user during the performance of an exercise on the exercise machine.

A weightlifting machine that includes a pulley system and a cable system that attaches to a weight rack frame to allow a user to perform a weightlifting exercise. The pulley system may include a first pulley and a second pulley where the cable system engages each pulley. The cable system may have a first end connected to a grip attachment and a second end attached to a resistance element. The resistance element may include a resistance band, a weight support that holds a weight plate, a set of weight plates, or other type of resistance element. The cable system may extend from the pulley through an opening located one of the frame members that form the frame.

A bicycle trainer, including a base, permitting fore and aft movement and a frame, supported by the base. Also, a seat and a handlebar assembly and a pedaling assembly is supported by the frame. The handlebar assembly is rotatably engaged to the frame, and is supported by a tongue, that is hinged to the base so as to permit horizontal rotation, and the handlebar assembly is attached to the tongue at a position removed from the hinge. Turning the handlebars causes the frame to move laterally.

An exercise machine accessory system for facilitating exerciser rehydration during a workout and antibacterial machine wipe down. The exercise machine accessory system generally includes an exercise machine having a first end and a second end, first and second stationary exercise platforms, a movable carriage movably positioned upon a rail, a biasing member connected to the movable carriage, first and second handle assemblies connected to the frame of the exercise machine, a first bottle holder, a first antibacterial wipes dispenser and/or a first disposal receptacle connected to the first right handle assembly or the first left handle assembly.

A physical therapy device includes a brace to secure around an appendage of a person; a first locking device connected to a portion of the brace via a rivet joint, the first locking device having a gear; a pawl positioned to engage with the gear; a spring connected to the pawl to provide tension to the pawl; and a lock to release the pawl from the toothed gear; the first locking device is positioned next to a joint of the appendage when worn; the first locking device allows for single direction movement of the joint; and the first locking device is to release the joint via the lock.

An improved barbell having horizontal spring-loaded resistance for increased muscular activity in an individual is provided. Spring action created by the horizontal spring-loaded resistance in the improved barbell provides the individual with additional muscle activation as compared to a traditional barbell. The improved barbell may include a spring that can be compressed and uncompressed using a tubular steel shaft, which is maintained in place by a self-lubricating linear bearing to reduce binding. The design provides a smooth action consistent with muscle-building execution exercises. The spring and bearing may be encased in a barrel with precision. The barrel may be welded to a 1-inch diameter steel tubular shaft. A separate 1-inch diameter steel tubular shaft may be installed in the barrel. The pair of tubular shafts may hold a desired weight.

An exercise machine resistance adjustment system for providing an exerciser the ability to immediately adjust the resistance force by changing their body position on the movable carriage or end platforms. The exercise machine resistance adjustment system generally includes a frame, a carriage movably positioned on the frame, a spring connected to the carriage to apply a biasing force to the carriage, one or more left projections within the carriage adapted for a left hand of an exerciser to grasp, and one or more right projections within the carriage adapted for a right hand of an exerciser to grasp. The exerciser is able to efficiently adjust the amount of resistance force applied to the carriage by repositioning their hands (or feet) from a first set of projections at a first distance to a second set of projections at a second distance from the first end of the exercise machine.
