Abstract: A stationary strength training equipment includes a frame assembly, a lockable bilateral user interface installed on the frame assembly, a balancing structure connected to the lockable bilateral user interface, a plurality of user selectable weights supported by the frame assembly and connected to the balancing structure, a load detecting strain gauge disposed on the user selectable weights to detect a weight of the user selectable weights being lifted, and an informing device connected to the lockable bilateral user interface to detect and show a warning signal to a user. The lockable bilateral user interface further includes a locking mechanism assembly and a central pivot assembly; the balancing structure is able to rotate along the central pivot assembly, and the locking mechanism assembly selectively restricts a rotation of the balancing structure.

Abstract: A stationary exercise equipment has a supporting structure, a movable user interface connected to the supporting structure, and a force-resisting device. The force-resisting device with a hub mounted continuously variable transmission configured therein provides a variable resistance force that varies an amount of force with a movement of the movable user interface. The hub mounted variable transmission is operably to vary the resistance force of the movable user interface in a manner of varying a rotational rate of the user interface to increase or decrease as required.
