During the study period, the control group will not participate in any physical activity. Before training program, and 48 hours after the last training session, measurements of waist circumference and blood pressure, as well as blood samples in the fasting state will performed to measure irisin, glucose and insulin resistance. Intervention 2: Control group: without any exercise.
