An exercise machine is operable in a first mode for simulating a cycling activity and operable in a second mode for simulating a stair climbing activity. The machine comprises a frame and a flywheel operatively connected to the frame for rotation relative to the frame about a flywheel axis. At least one stepping member is operatively connected to the frame for movement relative to the frame between raised and lowered positions. The stepping member has a stepping surface positioned and configured to be stepped upon by a user. A stair-climbing drive mechanism is operatively connected to the stepping member and operatively connected to the flywheel in a manner to cause the flywheel to rotate about the flywheel axis upon movement of the stepping member from its raised position to its lowered position. At least one crank is operatively connected to the frame for motion in a circle about a crank axis. A cycling drive mechanism is operatively connected to the crank and operatively connected to the flywheel in a manner to cause the flywheel to rotate about the flywheel axis upon circular movement of the crank about the crank axis.
