  • Patent number: 9039585
    Abstract: An exercise machine includes a frame, a pivotable body support assembly, a lifting mechanism in parallel linear engagement with the frame, and a counter balance assembly connected to the body support assembly, wherein the body support assembly is pivotable from a downward position to a top position. The lifting mechanism includes a foot plate, an ankle pad, and a foot pad. The lifting mechanism also includes a lifting assist mechanism, such as a spring or gas shock. The counter balance assembly partially balances a body weight of a user as the body support assembly is pivoted from the downward position to the top position. A method of using an exercise machine includes stepping onto the foot plate and securing the back of a user's foot against the ankle pad, releasing the lift assist mechanism, and bringing the foot plate to the toe pad.

  • Patent number: 8540610
    Abstract: An exercise machine includes a frame, a body support assembly in pivotable engagement with the frame, and a counter balance assembly connected to the body support assembly, wherein, in operation, the body support assembly is pivotable from a downward position to a top position. The counter balance assembly partially balances a body weight of a user in a prone position against the body support assembly as the body support assembly is pivoted from the downward position to the top position. The counter balance assembly may include a reaction arm extending from a rear portion of the body support assembly and pivotable about the frame, and may include a weight bearing end opposite the body support assembly. A method of using an exercise machine includes positioning a user body prone against a body support assembly, wherein the body support assembly is pivotally engaged with an exercise machine frame and counterbalancing the user's bodyweight.
