         3 . The treadmill in accordance with  claim 1 , wherein the base includes at least one crossbar connected to the longitudinal bars. 
     
     
         4 . The treadmill in accordance with  claim 3 , wherein each of the cushions further includes a block attached to the related longitudinal bar, wherein the cushioning strip is supported on the crossbar and the block. 
     
     
         5 . The treadmill in accordance with  claim 4 , wherein the cushioning strip is attached to the crossbar at an end and attached to the block at another end. 
     
     
         6 . The treadmill in accordance with  claim 4 , wherein the cushioning strip is bent and therefore includes a bent portion, two ends, and two overlapped portions each extending between the bent portion and a related one of the ends, wherein the ends of the cushioning strip are secured to the crossbar, wherein the bent portion of the cushioning strip is wound on the block. 
     
     
         7 . The treadmill in accordance with  claim 6 , wherein each of the cushions further includes a screw for securing the ends of the cushioning strip to the crossbar. 
     
     
         8 . The treadmill in accordance with  claim 7 , wherein each of the cushions further includes a plate secured to the crossbar by the screw, wherein the ends of the cushioning strip are sandwiched between the plate and the crossbar. 
     
     
         9 . The treadmill in accordance with  claim 4 , wherein each of the cushions includes two auxiliary elements attached to the related longitudinal bar and located between the crossbar and the block, wherein the cushioning strip is supported on the auxiliary elements so that the tension in the cushioning strip is increased. 
     
     
         10 . The treadmill in accordance with  claim 9 , wherein each of the auxiliary elements is a bent rod formed with a horizontal section inserted in the related longitudinal bar and an included section abutted against the related longitudinal bar. 
     
     
         11 . The treadmill in accordance with  claim 1 , wherein each of the cushions further includes two blocks attached to the related longitudinal bar, wherein the cushioning strip is supported on the blocks. 
     
     
         12 . The treadmill in accordance with  claim 11 , wherein the cushioning strip is an endless loop wound on the blocks. 
     
     
         13 . The treadmill in accordance with  claim 12 , wherein each of the cushions includes two auxiliary elements attached to the related longitudinal bar between the crossbar and the block, wherein the cushioning strip is supported on the auxiliary elements so that the tension in the cushioning strip is increased. 
     
     
         14 . The treadmill in accordance with  claim 13 , wherein each of the auxiliary elements is a tube connected to the related longitudinal bar. 
     
     
         15 . The treadmill in accordance with  claim 1 , wherein each of the cushions further includes a contact element formed with a planar upper side attached to the platform and an arched lower face in contact with the cushioning strip. 
     
     
         16 . The treadmill in accordance with  claim 15 , wherein the contact element further includes two walls formed thereon for restraining the cushioning strip. 
     
     
         17 . The treadmill in accordance with  claim 16 , wherein a distance from the arched lower face to the edge of each of the walls is longer than the thickness of the cushioning strip.
