Study Type Interventional
Study Design Allocation: Randomized;   Intervention Model: Parallel Assignment;   Masking: None (Open Label);   Primary Purpose: Treatment
Conditions Metabolic Syndrome
Obese
Sedentary
Interventions Drug: Statin
Other: Exercise only
Other: Statins + Exercise
Enrollment 121
Recruitment Details If meeting qualifications after initial phone screening, subject consented followed by another round of screening to determine if they had 2/5 risk factors or not which eliminated many subjects. Thus the difference between the 121 subjects reported for who signed consents and the 50 who entered the participant flow module.
