Abstract: An omnidirectional rocking chair for abdominal exercise has a rectangular support base with a convex lower support surface with variable radii of curvature. The chair back supports only the user's lower back. Rocking the chair develops outward momentum in the mass of the user's upper back, arms and head. The minimum lower support surface radius of curvature is in its central portion and the center of that curvature is above the center of gravity of the seated user and chair. The peripheral portions of the lower support surface have larger radii of curvature. The corner portions of the lower support surface have maximum radii of curvature. The effect of progressive increase in support surface radius of curvature is to increase righting moment in the rocking motion where the respective larger radii portions contact the floor.

Abstract: An all-in-one exercise machine that is designed to increase a user's speed, agility, and strength uses a treadmill, either motorized or manual, that can be inclined. A resistance hub attaches via a cable to a body harness worn by the user and acts as a resistive take up reel against the user's running. Smaller resistance hubs attach via cables to elbow and hand sleeves worn by the user and resist against the back and forth arm movements of the user while the user is running on the treadmill. These latter resistance hubs also act as weight resistance hubs for weight training on the device, the cables having appropriate weight lifting implements attached thereto.

Abstract: An exercise machine allows a user to perform a variety of resistance exercises with adjustable resistance levels. The machine is made up of an arm, a user platform, a horizontal base, an adjustable counterweight arrangement, a pull rod, a drive chain system, sprockets, shafts, adjustable fan, a slip bearing, a recoiler, a plurality of wheels, a drive chain system housing, a user back support, a user cable grip, and a circuit-breaking sensitive rubber mat. When the arm is moved upwards (by a user) the pull rod attached to a drive chain initiates the drive chain system rotation. The drive chain system rotation includes an adjustable weight fan that creates resistance to the arm's upper movement through inertia. The adjustable counterweight arrangement determines the arm drop speed and the arrangement has multiple positions. Other variants include a plurality of electronic encoders.
