1. A treadmill comprising:
a front end;
a rear end;
a belt defining a running surface that extends substantially between the front end and the rear end;
one or more lifting mechanisms configured to adjust an orientation of the running surface about a pivot point positioned between the front end and the rear end, wherein the one or more lifting mechanisms comprise:
a first motor;
a first connector operatively connecting the first motor to a first portion of the treadmill adjacent the front end;
a second motor; and
a second connector operatively connecting the second motor to a second portion of the treadmill adjacent the rear end; and
computing hardware configured to control each of the first motor and the second motor to adjust a length of the first connector and the second connector to adjust the orientation of the running surface about the pivot point, wherein:
the first connector operatively connects the first motor to the first portion of the treadmill via at least one rotating connector; and
the at least one rotating connector comprises at least one of a sprocket or a pulley.
