An airflow pathway may be defined to direct air from the cooling mechanism to a location above the motor housing and on to a user of the exercise machine. The exercise machine may be configured such that upon beginning operation of the machine, substantially all of the airflow exhausts to the location above the motor housing. A mechanism may be provided to selectively alter a characteristic of the airflow after the exercise machine has begun operation. ## Claims ### Claim 1 An exercise machine comprising: a deck; a motor housing incorporated into the deck; a console positioned at an elevation above the motor housing; a fan associated with at least one of a lift motor and a drive motor located in the motor housing; an airflow pathway extending from a location adjacent the fan through a first outlet vent located in a location above the motor housing; and a mechanism configured to selectively alter airflow flowing through the airflow pathway. ### Claim 2 (depends on 1) The exercise machine of claim 1, wherein the mechanism includes a clutch coupled with the fan. ### Claim 3 (depends on 2) The exercise machine of claim 2, wherein the clutch includes an electromagnetic clutch. ### Claim 4 (depends on 3) The exercise machine of claim 3, wherein the clutch is in a normally engaged state. ### Claim 5 (depends on 1) The exercise machine of claim 1, wherein the mechanism includes a diverter. ### Claim 6 (depends on 5) The exercise machine of claim 5, wherein the diverter is displaceable between at least two different positions, including a first position wherein substantially all airflow is directed through the first outlet vent, and a second position wherein all airflow is directed through a second vent to a location away from the location above the motor housing. ### Claim 7 (depends on 6) The exercise machine of claim 6, wherein the diverter is displaceable to at least a third position wherein a first portion of the airflow is directed through the first outlet vent and a second portion of the airflow is directed through the second outlet vent. ### Claim 8 (depends on 5) The exercise machine of claim 5, wherein the diverter is in the first position upon starting operation of the exercise machine. ### Claim 9 (depends on 1) The exercise machine of claim 1, further comprising at least one post member extending from a location adjacent the deck up to the console, and wherein the airflow pathway extends through an interior portion of the at least one post member. ### Claim 10 (depends on 9) The exercise machine of claim 9, further comprising an inlet vent formed in the at least one post member and in fluid communication with the airflow pathway. ### Claim 11 (depends on 1) The exercise machine of claim 1, further comprising at least one auxiliary fan disposed within the airflow pathway. ### Claim 12 (depends on 11) The exercise machine of claim 11, wherein the at least one auxiliary fan is configured to begin operation upon starting operation of the exercise machine. ### Claim 13 A method of operating an exercise machine, the method comprising: providing a deck with a motor housing; providing a motor in the motor housing to alter an operating characteristic of the deck; providing a fan to circulate air over the motor; providing an airflow pathway from a location adjacent the fan, to a first exhaust vent located in a console of the exercise machine; exhausting substantially all airflow from the fan through the first exhaust vent to a location above the motor housing upon starting the exercise machine; altering at least one characteristic of the airflow through the airflow pathway during subsequent operation of the exercise machine. ### Claim 14 (depends on 13) The method according to claim 13, wherein altering at least one characteristic of the airflow includes turning off the fan. ### Claim 15 (depends on 13) The method according to claim 13, wherein altering at least one characteristic of the airflow includes diverting at least a portion of the airflow through a second exhaust vent. ### Claim 16 (depends on 13) The method according to claim 13, wherein altering at least one characteristic of the airflow includes diverting substantially all of the airflow through a second exhaust vent. ### Claim 17 (depends on 13) The method according to claim 13, wherein altering at least one characteristic of the airflow is responsive to a user command. ### Claim 18 (depends on 13) The method according to claim 13, wherein altering at least one characteristic of the airflow is responsive to a command associated with a predefined workout program. ### Claim 19 A treadmill, comprising: a deck; a motor housing incorporated into the deck; a first pulley incorporated into the deck; a tread belt incorporated into the deck and in engagement with the first pulley; a drive motor located within the motor housing in mechanical communication with the first pulley; a flywheel being rotationally fixed with respect to the drive motor where the drive motor causes the tread belt to move in a rotational direction and causes the flywheel to spin; a lift motor located within the motor housing; a fan assembly that cools the lift motor; a console; at least one post member extending from a location adjacent the deck to the console; an airflow path extending from the fan, through the at least one post member, through an exhaust vent located in the console; and a mechanism configured to selectively alter airflow flowing through the airflow pathway.
