Abstract: A user weight resisted rowing exercise simulation machine with a movable user support pivotally connected to a forward portion of a stationary horizontal base frame and a slidable seat and rigid feet support mounted to the movable user support frame and a pulling handle operatively connected to the movable user support frame such that moving the pulling handle towards the rearward portion of the machine causes the rearward portion of the user support frame to pivot upward and moving the pulling handle away from the rearward portion of the machine causes the rearward portion of the movable user support to pivot downward and the force required to move the pulling handle towards the rearward portion of the machine is reduced and controlled by the operative connection of the pulling handle to the user support frame.

Abstract: Improved exercise machines having a movable user engagement member and a user support movably mounted on a movable slide support surface and a slidable wedge concurrently engaging the movable slide support surface and a stationary slide support surface and an operative linkage system connecting the user engagement and the slidable wedge such that movement of the user engagement causes the slidable wedge to engage the slide support surfaces changing the distance between at least a portion of the slide support surfaces and thereby creating a multi-dimensional articulating movement of the user support during an exercise motion.

Abstract: A series of improved exercise machines with a movable user engagement member operatively linked to a sliding while rotating user support such that when the user engagement member is engaged and activated by the user the user engagement member concurrently causes movement of the operative linkage system, which concurrently causes the user support to slide while rotating. This creates dynamic motion of the user support relative to the user engagement member.

Abstract: A machine for concurrently exercising one or more of a user's muscle groups, the machine having a base having front and back ends, one or more linear slide rails, a user support and an engagement member for the user's hands or feet. The user support slides while pivoting during the exercise motion such that the location and angle of the user support is dictated by the linkage mechanism that positions and connects the user support relative to the other parts of the machine. The user support can be caused to move by the engagement member being acted upon by the user's feet only, by the user's hands only or a combination of the user's feet and hands concurrently during the exercise.

Abstract: An exercise treadmill having an endless exercise surface for walking or running while exercising, a resistance mechanism for providing a resistance for simulating the pushing of a load, wherein the resistance can be adjusted and set to a specific resistance setting. A movable pushing handle or handles is or are operatively attached to the resistance mechanism to transfer the load to the user. The resistance mechanism applies a constant and static force to the pushing handle(s) only in the same direction the endless movable surface moves and opposite a pushing direction such that operating the treadmill simulates the pushing of a load by a combination of gripping and pushing the pushing handle(s) forward while walking or running forward.
