An isolation exercise machine for exercising one muscle group has a user support which is pivotally mounted on a main frame by a pivotal mounting system. A user engaging exercise arm is pivotally connected to the user support, and a connecting link links movement of the user exercise arm to movement in the user support. A load provides resistance to movement of the user support, exercise arm and/or connecting link. The pivotal mounting system is configured to place the user support seat in a relatively flat position in the rest or exercise start position and to recline and change the seat angle to an inclined position as the exercise arm is moved.
