Abstract:
A fitness machine providing shock absorption for a user operating the fitness machine. The fitness machine includes a base and a mobile portion engageable by the user and moveable relative to the base during operation of the fitness machine. A resilient body resists movement of the mobile portion towards the base in a height direction, where the resilient body has first and second ends defining a length therebetween, and where the length is defined in a length direction that is perpendicular to the height direction. A stop wall is engageable by the resilient body, where the length of the resilient body increases when the mobile portion moves towards the base until the second end engages with the stop wall. The resilient body provides shock absorption for the user.
