Abstract: A fitness machine providing shock absorption for a user operating the fitness machine. The fitness machine includes a base, at least one member engageable by the user and moveable relative to the base during operation of the fitness machine, and a resilient body that resists movement of the at least one member towards the base so as to provide shock absorption for the user, wherein the resistance provided by the resilient body is adjustable. The fitness machine further includes a control system configured to receive from the user a shock setting corresponding to how much shock absorption is desired, and to receive other than from the user a secondary input, wherein the control system is further configured to adjust the resistance provided by the resilient body based on the shock setting and the secondary input.

Abstract: A fitness machine operable by a user. The fitness machine includes a base that extends in a length direction, a width direction, and a height direction that are perpendicular to each other. A mobile portion is configured to support the user during operation of the fitness machine. A resilient body is configured to provide a resistance against the mobile portion moving towards the base in the height direction. A frame is moveable in the length direction relative to the base to adjust the resistance provided by the resilient body. A fastener assembly moveably couples the frame to the base, where the fastener assembly is configured to expand in the width direction to prevent the frame from moving in the width direction relative to the base during operation of the fitness machine.

Abstract: A fitness machine operable by a user. The fitness machine has a base and a mobile portion that moves relative to the base during operation. A resilient body resists movement of the mobile portion towards the base in a height direction. The resilient body has a length defined in a length direction that is perpendicular to the height direction. The length of the resilient body increases when the mobile portion moves towards the base. An end stop is operable to prevent the length of the resilient body from increasing beyond a set maximum. The end stop is moveable to adjust the set maximum for the length of the resilient body, where a resistance provided by the resilient body to resist movement of the mobile portion towards the base is unaffected by moving the end stop when the length of the resilient member is less than the set maximum.

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.
