Generally speaking, just stick to it. Because this test is mainly to measure your cardiopulmonary function. In other words, there will be an instrument to measure the initial heartbeat at the beginning. I pinched my fingers and stepped on the steps. When finished, continue to use the machine just now. Every once in a while (maybe 1min, I can't remember), my heartbeat will be measured, and it should be three times. In other words, the closer the heartbeat returns to its initial value, the better. It seemed beyond my control at that time. In short, don't be nervous, just do as required. Maybe the steps are hard to step on.
