Mary is a 42-year-old woman who has been living with a diagnosis of relapsing-remitting multiple sclerosis for over 20 years. Her illness is well managed with medication, but she does experience occasional issues with getting overheated and bouts of fatigue. Due to frequent corticosteroid use for her MS in her 20s, she has recently been diagnosed with type 3 osteoporosis. She doesn't notice many symptoms from this diagnosis, but it may explain her occasional low back aches. Unfortunately, Mary has been inactive and has not been in a structured exercise program for many years. As a result, she has gained some weight, and her fasting glucose is 141 mg/dl. Her fasting glucose number was a wake-up call for her, and she realized that she needed to start exercising to improve her health. Her doctor has provided clearance for her to start exercising. Due to your expertise, you have been recommended to provide a program for Mary. What risk category would you place Mary into, and why?
