Study Arms:
- Clinic-based outpatient exercise group (Type: EXPERIMENTAL): Subjects will participate in supervised sessions (clinic-based) of exercise followed by a home exercise program 2 times per week during 3 months. Each exercise session will last about 60 minutes. Treatment sessions will utilize a pragmatic approach and will include the exercises designed to increase muscular strength, low impact cardiovascular exercise, range of movement, and activity for daily living skills.
- Community-based exercise group (Type: ACTIVE_COMPARATOR): Subjects will attend to exercise classes (community-based) 2 times per week during 3 months. The exercise classes last approximately 60 minutes. The group exercise classes consists of a variety of exercises designed to increase general muscular strength, low impact aerobic exercise, range of movement, and activity for daily living.
- Wait-listed usual medical care (Type: NO_INTERVENTION): Wait-listed usual medical care - no intervention provided by study.

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