• The CT-9100 and CT-9500HR, and 9500HR Next Gen are the oldest versions of what we call the classic motion of the Life Fitness.

• 91x, 91xi, and Integrity CLSX all have the SAME classic motion but are newer.

• We would personally recommend CLSX for someone instead of 9500HR. It's only a couple hundred more and much newer.

• X9i, Club, CT9500hr, 9500HR Next Gen, CT-9100 , 91xi, 91x, CLSX Integrity have the same motion.

• Any of the other Life Fitness Ellipticals will have a different motion and you might or might not like the feel of the different motion

ALL machines below have same mechanics and most non-electronic parts are interchangable.
