I think what is most important in a stress test
, is evaluating how hard your heart
can work before problems occur, and identifying those problems. It is also important that you CAN reach your optimum, or there is definitely something amiss. I had no idea it was on a time based thing, to me that would be like a race. Every stress test I've had, the operator has always said "ok I will now speed it up a bit more" or "It will now increase in incline".
