Rise up for your health
The sit-and-rise test helps assess your physical function.
Try this without touching your hands or knees to the floor: from a standing position, sit on the floor with your legs crossed or straight out. Now stand up again. (This is not an easy movement for many people, so for safety do it with someone next to you.)
How did you do? Did you struggle? Did you need to put your hand or a knee on the ground? Could you not get up?
