16. The treadmill as recited in claim 11 , wherein said first impact absorbing mechanism and said second impact absorbing mechanism enable movement of said deck by a downward movement greater than defined by said first relation for a given force.
17. The treadmill as recited in claim 1 , wherein said first impact absorbing mechanism and said second impact absorbing mechanism enable movement of said deck more than 1.5 inches.
18. A treadmill comprising:
a frame comprising a lower portion, wherein said lower portion has a securing location;
a platform linked to said lower portion of said frame at said securing location and extending therefrom;
an endless belt, said belt having an upwardly exposed exercise section;
a deck disposed between said exercise section of said belt and said frame, wherein at least a portion of said deck extends beyond said securing location of said frame away from said exposed exercise section when the treadmill is positioned on a support surface for use by a user; and
an impact absorbing mechanism linked to said platform and said deck, said impact absorbing mechanism being configured to cushion an impact upon said deck, said impact absorbing mechanism comprising:
a cushioning member;
a first cup linked to said deck; and
a second cup linked to said platform;
wherein said first cup and said second cup retain said cushioning member.
19. The treadmill as recited in claim 18 , wherein said impact absorbing mechanism enables movement of said deck more than about 1.25 inches upon application of 600 lbs of force to said deck.
