US Patent 10576331 Composite motion exercise machine

A composite motion exercise machine includes a control panel which provides a plurality of movement modes and allows a user to issue a command to change the configuration of linkage units of the exercise machine to have the machine perform a movement mode without manual adjustment, so that the pedal of each linkage unit can be moved along a closed trajectory. The control panel also allows the user to finely adjust the trajectory and the resistance associated therewith. The trajectory performed by each pedal of the exercise machine is ergonomic so that the user can be protected from exercise injury.
