    摘要： An exercise machine has a crankshaft having a crankshaft mounting surface, a landing surface, and a crankshaft bore, a crank arm having a threaded crank arm bore and a crank arm mounting surface that is frictionally engaged with the crankshaft mounting surface, and a fastener that axially extends through the threaded crank arm bore and into engagement with the crankshaft bore to fasten the crank arm to the crankshaft. The threaded crank arm bore is configured for threaded engagement by a removal tool such that removal of the fastener and insertion and rotation of the removal tool in the threaded crank arm bore causes the removal tool to disengage the crank arm mounting surface from the crankshaft mounting surface and thus facilitates removal of the crank arm from the crankshaft. Methods of disassembling an exercise machine having a crank arm are also provided.

    摘要： There is disclosed a system for adjusting a stiffness of a running deck for a treadmill having a base, the system comprising:
    a bracket configured to be coupled to the base of the treadmill;
    a resilient body adapted to resist movement of the running deck towards the base in a height direction, wherein the resilient body has first and second ends defining a length therebetween, wherein the length is defined in a length direction that is perpendicular to the height direction, and wherein the first end is pivotally coupled to the bracket;
    a stop wall that is adjustably fixable relative to the base, wherein the length of the resilient body is caused to increase when the running deck moves towards the base until the second end engages with the stop wall; and
    an adjustment device coupled to the stop wall, wherein the adjustment device is configured to move the stop wall in the length direction to change the length of the resilient body when the second end thereof engages with the stop wall. There is also disclosed a treadmill including the system.

    摘要： There is disclosed exercise equipment for performing a striding exercise motion, the exercise equipment comprising:
    a frame,
    a rocker arm which is pivotably coupled to the frame,
    a pedal member which pivots with the rocker arm relative to the frame, and
    a pivot device which pivotably couples the pedal member to the rocker arm,
    wherein the pivot device comprises a dampener configured to dampen pivoting movement of the pedal member relative to the rocker arm.
