Onsite vs. Virtual Group Fitness in Overweight/Obese Women

Study Overview
=================
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.
