 A submaximal exercise bicycle test will be done to assess aerobic capability, and a 6 minute walk test, sit to stand and get up and go tests will be done to assess overall functional status by the physical therapy PT department. Those who are not randomized to exercise at the baseline visit, will have one repetition maximum 1 RM testing. The 1 RM is defined as the maximal amount of weight that can be lifted throughout full range of motion. The 1 RM will be tested by performing exercises including calf raises, arm curls, lateral raises, knee flexors, bench press and half squats. The 1 RM testing will be repeated on those who are not randomized to exercise at the 8 and 16 week visits.
