An exercise device (1) capable of performing three discrete exercise activities, and including a treadmill (9) suitable for simulating a running or walking exercise, and further including a pair of slidable foot restraints (34, 35) mounted within rails (56, 57) adjacent to the treadmill (9) in order to simulate a cross country skiing exercise. A pair of reciprocating, pivotable foot paddles (58, 59) are cooperatively attached in a first embodiment to pneumatic cylinders (89, 90), while in a second embodiment are cooperatively attached to conical resistance mechanisms (112, 113) so as to simulate a stair climbing activity. A pivotable torso support (11) is provided to assist the balance of a person performing any of the three exercise activities.
