• Weight stable for at least three months
• Able to understand and speak English

You may not qualify if…

• Failure to provide informed consent
• A 10% enrollment limit will be applied to avid exercisers in each age decade. Avid exercises will be defined as doing structured exercise 3 or more days per week (e.g. jogging, sports etc., walkers will be permitted in the study). Based on our experience, avid exercisers volunteer for this type of research at a high rate and thus the investigators will limit these individuals to prevent a biased comparison
• Use of walker (use of a cane is permitted)
• Lower extremity amputation
• Develops chest pain or severe shortness of breath during physical stress
• Post-stroke syndrome causing ambulatory deficits (other stroke survivors permitted)
• Pacemaker
• Needs assistance with basic activities of daily living: feeding, dressing, continence, bathing, toileting, and transferring from a bed to a chair or from a chair to walking

• Participation in a structured weight loss program or fad diet in the last month;
• Weight reduction surgery in the past year
• Known neuromuscular disorder (Rhabdomyolysis, Myasthenia Gravis, Ataxia, Apraxia, post-polio syndrome, mitochondrial myopathy, chronic fatigue syndrome etc.)
• Diagnosed neuropathy that causes pain
• Symptomatic peripheral arterial disease
• Unable to communicate because of severe hearing loss or speech disorder
• Severe visual impairment, which would preclude completion of the assessments
• Progressive, degenerative neurologic disease, e.g., Parkinson's Disease, Multiple Sclerosis, Amyotrophic lateral sclerosis
• Severe rheumatologic or orthopedic diseases, e.g., awaiting joint replacement, active inflammatory disease; self-reported severe osteoarthritis
• Terminal illness, as determined by the participant
• Severe pulmonary disease, requiring the use of supplemental oxygen or steroid therapy
• Severe cardiac disease, including New York Heart Association Class III or IV congestive heart failure, clinically significant aortic stenosis, recent history of cardiac arrest, use of a cardiac defibrillator, or uncontrolled angina
• Other significant comorbid disease discovered during medical screening, e.g. renal failure on hemodialysis, psychiatric disorder (e.g. bipolar, schizophrenia); chronic fatigue syndrome etc…
