  • Method and system for varying stride in an elliptical exercise machine
    Patent number: 7901330
    Abstract: Disclosed is an exercise machine, and particularly a front or rear mount elliptical or elliptical-type machine, comprising: (a) a support structure; (b) a drive component pivotally coupled to the support structure and configured to rotate about a first pivot axis; (c) a reciprocating foot support configured to travel about a closed path having a stride length upon rotation of the drive component; (d) a coupling configuration configured to support the reciprocating foot support about the drive component at a position radially offset from the first pivot axis, the coupling configuration pivotally coupled to the drive component about a second pivot axis; and (e) an adjustment mechanism configured to enable the coupling configuration to pivot about the second pivot axis between at least two adjustment positions to vary the radial offset of the reciprocating foot support with respect to the first pivot axis.
