Treadmill selection guide:

1 - Motor: 3.5 CHP or higher
2 - Belt/Deck:  W/L: 20"/60" minimum. A reversible deck is a very nice feature on a running treadmill.
		A reversible feature will double the life of your treadmill deck. 
		Also make sure that the deck is pre-treated or impregnated with lubricant. 
		Running at fast paces builds up a lot of friction between the deck and belt. 
		The lubrication will decrease the friction and increase belt and deck life. 
		It will also reduce the load on the motor.
