Observational studies are permitted~* Participation in progressive resistance exercise regimen ( ≥1 day/week) within the previous 6 months prior to screening.~* Weight change (intentional or not) over the last 6 months of \> 5% of body or plan to lose or gain weight during the study~* Any other cardiovascular, pulmonary, orthopedic, neurologic, or other conditions that in the opinion of the local clinician would preclude participation and successful completion of the protocol~Temporary Exclusion Criteria:~* Recent bacterial/viral infection (e.g. pneumonia) (\< 2 weeks);~* Acute febrile illness in past 2 months;~* Severe hypertension, e.g., SBP \> 200 mm Hg, DBP \> 110 mm Hg~* Major surgery or fracture or hip/knee replacement (\< 6 months);~* Hospitalization within the last 6 months ( Not ER visits)

- Gender: ALL
- Minimum Age: 70 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- Resistance Training group (RT) (Type: EXPERIMENTAL): The resistance training intervention will include a full body, resistance training performed three days per week.The intensity, volume, tempo, and progression will be based on the Federal Physical Activity guidelines
- Successful Aging (Type: ACTIVE_COMPARATOR): The comparator group will meet for stretching and health education classes every 2-5 weeks up to 7 total visits.

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

Answer: outcome: complete
