Researchers are trying to find out what impact training with whole body-EMS (Electronic muscle stimulation) has on various health outcomes.
All subjects in both groups who enroll into this study will undergo an assessment of peripheral endothelial function with reactive hyperemia-peripheral arterial tonometry (RH-PAT) testing using EndoPAT; an assessment of vital signs including heart rate, blood pressure, weight, height and body mass index; laboratory blood work; cardiorespiratory testing using treadmill testing to determine VO2 max and maximal tolerated heart rate; maximal strength and maximal power testing on chest press and leg press testing; and percent body fat and fat distribution testing at baseline, and at 16-weeks follow-up (immediately after completing a 16-week training program using whole body-EMS). Baseline cardiovascular risk factors will be assessed by subject questionnaire and verified by chart review. In addition, subjects will complete an angina/chest pain symptom questionnaire (Rose Questionnaire), quality of life questionnaire (LASA Questionnaire), depression questionnaire (Patient Health Questionaire-9) and perceived stress questionnaire (Perceived Stress Scale) to assess for psychosocial wellness at each point in the study.

| Measure | Description | Time Frame |
|---|---|---|
| Mean Change in Reactive Hyperemia Index (RHI) | Mean change in RHI. RHI measured by noninvasive endothelial peripheral arterial tomography (EndoPat) test. The EndoPAT involves probes on the index fingers of both hands & evaluating the blood flow to one hand before & after inflating a blood pressure (BP) cuff on one arm, temporarily reducing blood flow to the fingers. The finger sensor on the affected arm will show no blood flow, the sensor on the opposite index finger will display normal blood flow level. After several minutes, the BP cuff is released, allowing blood to flow back into the affected lower arm. If the finger sensor on the affected arm shows a rush of blood, the blood vessels are functioning normally. If the blood flow return is sluggish, the blood vessels are unhealthy. EndoPAT results are reported as the "Endoscore" (range 0-3); a score of 1.67 and lower indicates the need for immediate medical attention; a score between 1.68 and 2 indicates a need to reduce risk factors; a score above 2.1 indicates a healthy heart. | baseline, 16 weeks |

Total cholesterol is the sum of a person's HDL cholesterol, LDL cholesterol, and 20% of their triglyceride levels. Healthy total cholesterol is less than 200 mg/dL of blood
| baseline, 16 weeks |
| Change in Maximal Oxygen Consumption (VO2max) | VO2 max, or maximal oxygen consumption, refers to the maximum amount of oxygen that an individual can utilize during intense or maximal exercise. VO2 max is the number of milliliters of oxygen used per kilogram of body weight in one minute (ml/kg/min) | baseline, 16 weeks |
