Exercise Program
Brief summary
The purpose of this study is to compare an onsite to virtual whole-body high intensity interval training (HIIT) program on anthropometric variables, aerobic fitness measures, and vascular markers of cardiac risk in a single study of overweight and obese women.
Interventions
OTHERHIIT Exercise Training
The HIIT total session duration will be approximately 30 minutes and will be composed of 10 sets of 60 seconds of high-intensity exercises, \>80% of maximum heart rate (MHR), interspersed with a recovery period of 60 seconds of low-intensity exercise at 60% of MHR.

| Pulse Wave Analysis Mean Arterial Pressure (MAP) | Up to 12 weeks | vascular marker of cardiac risk will be reported as MAP (mmHg) as measured using SphygmoCor |
| Visceral Adipose Tissue (VAT) content | Up to 12 weeks | Anthropometric measure will be reported as VAT content as measured by noninvasive direct segmental multi-frequency bioelectrical impedance body composition analyzer |
