We report six experimental and clinical studies conducted in several clinics around the world with a total of 407 multiracial subjects that examined the effects of an effortless exercise method, on visceral fat reduction, lipids profile, hormonal fluctuations, and muscle mass increase. The technology that acts as a virtual gym was invented in London University by the co-inventor of the first pacemaker. The first two within-subjects longitudinal experimental studies demonstrated a significant reduction in both visceral and subcutaneous adipose tissue, and a statistically significant increase of muscle mass on MRI scans. Additionally, there was a statistically significant increase in DHEA and T3. A statistically significant decrease in triglyceride serum levels was also noted. Two independent clinical studies revealed reduced body fat and increased muscle mass. One of these clinical studies also demonstrated increased BMR and bone density and decreased metabolic age, indicating an enhancement in the longevity quotient. When this effortless exercise (virtual gym) method was compared to gym workouts in a between-subjects design, it demonstrated a statistically significant advantage in terms of increased range and speed of motion on the goniometer results, metabolic boost and increased blood flow on the PET measurement. Cortisol Plasma levels and Cortisol Urinary Free levels decrease after effortless virtual gym. Exercise indicated that the stress associated with effortless exercise is significantly less than gym workouts. Time taken to run around the gym three times and time recorded to swim from one end of the pool lengthwise to the other, showed a significant advantage of fitness attained after the effortless virtual gym method, when compared to physical regular gym workouts. Moreover, effortless exercise demonstrated several advantages over the physical exercise gym workouts in terms of a reduction of body fat, inch loss, body shaping appearance, BMI reduction and evidenced a substantially greater muscle mass increase.
