Study Arms:
- Immediate Start (Type: EXPERIMENTAL): The Immediate Start group will participate in the Preventing Loss of Independence through Exercise (PLIE) group movement program for 1 hour, 2-3 days/week, for 4 months. After the intervention has been completed, they will be encouraged to maintain PLIE activities on their own for the next 4 months.
- Delayed Start (Type: ACTIVE_COMPARATOR): Study participants who are randomized to the Delayed Start control group will be placed on a waitlist and will be encouraged to continue participating in their usual activities at the adult day center or in their community setting for 4 months. After the 4-month waitlist period ends, they will participate in the PLIE program for 1 hour, 2-3 days/week, for 4 months.

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