What travel distance determines

Every exercise that involves extending the legs or reaching the arms is bounded by carriage travel. On a machine with short travel, a tall user reaches full extension before the carriage does, which truncates the movement at exactly the point where the work is happening.

This is the specification that separates a genuinely compact machine from a merely smaller one, and it is rarely published prominently.

Matching travel to height

As a rough guide, users over about 5 ft 10 in should be looking for travel at the upper end of the range. Below about 5 ft 4 in, shorter travel is rarely limiting.

If you are buying for a studio, specify for your tallest likely client rather than your average one — the short user can always work within a longer carriage travel, but not the reverse.

How to measure it

Push the carriage to its home position against the stopper, mark the frame, then push it to full extension and measure between marks. Do this with no springs attached.

On a used machine this is also a useful check for stopper wear — travel longer than the published spec usually means the carriage stoppers have compressed.
