This investigation will determine if frailty can be reversed through a multi-component exercise program. Females (65+ years of age) will be evaluated for the pre-frailty phenotype using the CHS and for characteristics of "vulnerable" and/or "mildly frail" using the CFS. To confirm frailty status, gait speed will be evaluated. A normal gait speed of 1-1.5 meters/second is associated with persons expressing the pre-frailty phenotype. Females who are pre-frail will randomized into the study as this demographic is at a critical-point of physical transition between frailty phenotypes. The objective is to reverse the frailty phenotype (pre-frail becomes non-frail) using a 16-week multi-component exercise program.
