The apparatus includes a seat or bench for a user to perform the weight lifting and cycling in one of a seated position, a supine position, and a partially supine position. The apparatus also includes a single or multi-level support for holding the resistance load adjacent the seat or bench, and movable foot pedals that are adjustable to a selected location in a two-dimensional plane at which the user performs cycling.

Abstract: The present invention provides an apparatus and method for exercising a body part from any angle with variable resistance while taking up minimal floor space. The apparatus improves the ability of athletes, including football players and wrestlers, to better prepare for contact from any angle while engaged in their sport. The apparatus includes a ring having a guide track therein. A first end of a resistive band may be received by and wrapped around the guide track while encompassing a source of resistance at another end. The source of resistance may be other gym equipment including a pulley. Alternatively, the guide track may be on an inner surface of a stationary outer ring configured to receive a bearing disposed on an outer surface of a rotatable inner ring. The inner ring may include an inflatable bladder disposed along its inside to provide a perfect fit.

Abstract: An abdominal and oblique exercise device is formed as a small, lightweight portable structure and configured to be used while in the sitting position. The device includes leg or thigh grips that engage the user's thighs and handlebars that are engaged by the user's hands. The leg grips are coupled to a stationary cylindrical main body member and the main body member includes three distinct grooves defining three distinct exercise movements. The handlebars are coupled to a moveable top piston received within the main body member. The piston includes a groove following projection that is selectively received in one of the three grooves in the main body member. The movement of the top piston relative to the bottom main body member will compress a resistance spring for resistance throughout the exercise. The grooves will define proper user movement for exercising to isolate the desired muscles.

The oxygen trainer assembly further includes a first endcap insert disposable in the first endcap operative to control the level of air resistance in the assembly during inhalation and exhalation and a one-way valve disposable in the second endcap sized and configured to allow the flow of air away from the circulation chamber during exhalation.

Abstract: A compact, portable, lightweight, easily transportable leg press exercise apparatus to simulate both exercise and the daily activity of sitting in a microgravity environment. The exercise portion of the apparatus creates stress on the lower extremities by supplying a variable resistance to a reciprocating foot pedal by way of a coil spring and damper system acting through a four-bar linkage. The chair is adjustable in angle to fit each user and to simulate a force that is two-thirds of body weight. By combining resistance exercise and lower body negative pressure with the LBNP leg press exercise apparatus, the users experience one or more times body weight (BW) in stress on their musculoskeletal, cardiovascular and nervous systems. By achieving one times BW or greater (artificial gravity) during exercise and two-thirds BW during sitting, the gap between the precondition and post condition syndrome will become smaller.
