An exercise machine has a mobile base and an upright support extending upwards from the mobile base. An upper support assembly extends forward from an upper portion of the upright support and an exercise device is suspended from the upper support assembly at a location spaced forward from the upright support. The mobile base has caster wheels and can be positioned from either side of a bed so as to extend partially under a bed with the upright support located on one side of the bed and the exercise device suspended over the bed in a position accessible by a patient lying supine in the bed for performing exercise. An anchoring system resists movement of the base for stability when exercise is performed.

A multifunctional arm cranking exerciser includes an omnidirectional support bracket assembly, which comprises a five-way bracket mounted to a top thereof and having a left side to which a left arm exercising device is mounted and a right side to which a right arm exercising device is mounted. Also mounted on the five-way bracket are a damping adjustment device and a quick release pin device. The quick release pin device allows for quick coupling and positioning of left and right arm cranks of the left and right arm exercising devices at an angular difference of 0 degree or 180 degrees and also allows for quick release and decoupling of the left and right arm exercising devices to be independent of each other. The damping adjustment device adjusts and regulates a level of damping for achieving an effect of efficient exercising.

The invention is an exercise apparatus providing an advanced level of surfboard paddling simulation and muscle development. The design includes a specialized platform, unique hand harnesses, and cable systems with mechanical advantage and mass moment of inertia mechanisms, piston pumps, cable spools, and elastic elements. They allow the user to simulate paddling in an alternating or simultaneous sequence at any speed while strong elastic tension resists the user's thrust strokes, but during paddling return strokes the user feels no elastic tension or resistance. The design also prompts the user to engage and strengthen all dorsal muscles to maintain an appropriately arched body position while paddling.

An apparatus for providing therapeutic rehabilitation exercise to bedridden individuals and patients, including comatose individuals. A vertical support column extends upwards from a base, with one or more arms extend from the vertical support column, each providing a rotary mechanism at the distal end, with pedals or handles attached thereto. The individual's feet or hands are secured to the pedals or handles, respectively. Straps, brackets, or other fastening means may be used to secure the feet and hands. An electric motor causes the rotary mechanism to move the pedals or handles in a rotary fashion, thereby providing movement and exercise for the individual's legs and arms.

A system and method for optimizing a person's muscle group performance thru modulating the arm, leg, and core muscle exertion rate based upon the exerciser's metabolic and geographic data. The system uses real-time measurement gathering and storing of physiologic parameters from humans during physical exercise activity and the geographic data of the exercise activity to determine information for optimizing the exerciser's physical exercise performance of the basic working muscle groups in the rider's arms, legs, and core. The system broadcasts to exercisers information including, but are not limited to: a) the current condition of their monitored muscle tissue, b) which muscle groups the riders should modulate and change their level of energy output during the exercise activity, and c) level of energy exertion at which riders should be employing at that moment in the relevant working muscle groups to optimize their physical exercise performance.

A treadmill may include a deck, a first pulley disposed in a first portion of the deck, a second pulley disposed in a second portion of the deck, a tread belt surrounding the first pulley and the second pulley, an upright structure connected to the deck, and a pull cable incorporated into the upright structure.

A treadmill may include a deck, a first pulley disposed in a first portion of the deck, a second pulley disposed in a second portion of the deck, a tread belt surrounding the first pulley and the second pulley, and a locking mechanism that selectively prevents the tread belt from moving.

Apparatus suitable for pilates and other exercise comprises rails, supported on a box-like frame and an exercise carriage, mounted on the rails, wherein the carriage comprises a first carriage section and a second carriage section which sections can be (i) connected together to form a single exercise carriage which slides forwards and backwards on the rails, or (ii) disconnected to form two exercise carriages which independently slide forwards and backwards on the rails. The apparatus also has a seat with a spring-biased foot pedal and a spring-biased trapeze bar.

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.

An exercise machine is provided for developing the chest muscles while maintaining correct biomechanical posture and joint movement for the user, thereby maximizing efficiency and safety. The exercise machine includes a track on which two platforms independently slide. The platforms are each interconnected to a weight stack unit or other vertical resistance unit that provide resistance to the inward movement of the platforms. Each platform may also be connected to a tension element or resistance band that is configured to provide gradual and progressively increased resistance as the platforms are moved inwardly towards the center or center stop of the track.
