THE SCIENCE

PROVEN: RESULTS SOAR WITH LES MILLS GRIT™ SERIES 

In conjunction with researchers at PennState University, we tested two groups of 42 fit adult exercisers. Both groups did five hours per week of excellent, professionally designed exercise.

Group 1 did three hours of cardio (either BODYATTACK™, BODYCOMBAT™, RPM™ or BODYSTEP™) and two 60-minute BODYPUMP™ classes.

Group 2 did exactly the same routine except it substituted one 60-minute cardio session for two 30-minute LES MILLS GRIT™ Series workouts.

After six weeks Group 1 achieved excellent results, recording marked increases in oxygen consumption and strength while decreasing triglycerides, decreasing body fat and reducing waist circumference. Group 2, who did the LES MILLS GRIT™ Series workouts, enjoyed the same benefits but on a much grander scale.
