Question
Does a stair-stepping machine give a high-impact or low-impact aerobic exercise?  Next question:  Does an elliptical exercise machine give an aerobic exercise? Thank you very much for your response to both questions. Al Brown

Answer
There are two kinds of stair-stepping machines.  One model has pedals that your feet stay in contact with continuously which makes in non-impact.  The other kind has rotating steps on a track in which you alternatingly step on, like a revolving staircase.  This makes it low-impact.

Elliptical trainers are for aerobic exercise.  They are also non-impact.

Hope you're exercising!
