Study Arms:
- no exercise program group (Type: None): group will continue with current level of activity and will be asked not to start an exercise program. They will be seen in the clinic three times a week for 12 weeks. These visits will be very brief; blood pressure, heart rate, oxygen level and peak flow will be measured at each visit
- exercise group (Type: None): will meet three times a week for 12 weeks, following specific exercise program

Based on this trial design, predict the completion outcome and termination type (if applicable).
