A speed controlled strength machine is provided. The machine includes a frame and a number of support members. A driver is mounted to the frame and includes an adjustable speed controller. During exercise, the user engages grips/handles and pulls them via one-way clutches through the resistive movement of the driver. The clutches are engaged when the user is able to reach a predetermined speed, which is adjustable and controllable.
