An exercise machine, such as a treadmill, has a user cooling system. The cooling system includes at least on fan that is mounted in a display console. The fan draws air through a duct and directs the air toward an upper portion of the user's body. In one arrangement, the fan and the duct are configured to reduce recirculation of air.

A new and improved exercise treadmill may include a frame having a first end and a second end, wherein the second end is parallel to the first end. Two sidewalls interconnect the first and second end. The treadmill may further comprise a motor in order to drive a belt, which is trained over a front roller and a rear roller. A deck is positioned underneath the belt in order to support the user. The treadmill may also comprise a belt tensioning device, which provides a visual indicator so that the rear roller may be moved on each end in equal distance relative to the front roller. Another feature of the invention is a slot between the side rails and the frame so that an extended member can be inserted therein to lubricate the belt.
A combination of treadmill and stair climbing machine includes a single roller supported on a shaft between two lugs on two sides of the frame of the combination and two rear ends of two pedals are respectively connected to the roller and supported on the two lugs. Two front ends of the two pedals are respectively connected to two hydraulic cylinders. A switch member is pivotably connected to a front end of the frame and can be set in a horizontal position when the combination is used as stair climbing machine, and an inclined position when the combination is used as treadmill. An L-shaped plate is connected to the frame and each pedal has a connection plate which has two elongate holes in which two protrusions on each side of the L-shaped plate are movably engaged, such that the pedals are pivotably supported on the L-shaped plate when used as stair climbing machine.
