The investigators hypothesize that those who are randomly enrolled into the exercise intervention will reverse their frailty phenotype on the CHS index (i.e. 'pre-frail' become 'non-frail') and restore physical function to lower levels (<4) on the CFS (i.e. 'vulnerable' become 'managing well'), while those in the control group will be unchanged or further regress in their frailty phenotype and become frail, or move further along the CFS toward greater levels of frailty. This research will provide support for the use of multi-component exercise as a proactive approach to restoring physical independence and quality of life for older adults.
