An exercise machine includes a bench and board section including a stationary bench having first and second opposite ends, and a board having first and second opposite ends, with the first end of the board pivotally mounted adjacent the second end of the stationary bench, each of the bench and board being formed substantially from a single piece which can selectively support a torso of a person and legs of the person, and a resistance device in contact with the single piece board and which applies a resistance to pivotal movement of the board, while permitting the board to swing up and down against a resistance applied by the resistance device.
