Experimental
No Intervention
Creatine Supplement Group
Exercise Only Control Group
Participants will engage in three center-based exercise sessions each week for 12 weeks; each session lasting roughly 1-hour. Participants will be given a fitbit (electronic watch that measures steps or heart rate) as well to track heart rate and monitor activity throughout the study.
Participants will not participate in the creatine intervention (creatine supplementation). Participants will engage in three center-based exercise sessions each week for 12 weeks; each session lasting roughly 1-hour. Exercise sessions will be held by trained study staff held at the Medical Arts and Research Center Physical Therapy clinic (address listed above).
