Visit your physician if you have a reason for requesting an approved excused absence from physical fitness activities at school or at work.
Inform your physician of the condition you have that permits you to receive an excused absence. You may be temporarily injured or sick, or you may have an existing and prolonged condition or disease that would make physical fitness activities a health risk.
Ask your doctor to write a certified note with his signature to indicate what is wrong with your health that should excuse you from the physical activities. Your request to the doctor could be worded in this way: "Dr. Smith, if you think that this condition puts my health at risk by engaging in physical activities, can you please write me a signed and certified note to approve my absence from physical activities at school? Thank you."
