About HIIT and it´s effectiveness: In a study that’s hot off the press, scientists found that sprint interval training is a time-efficient alternative to endurance training for increasing skeletal muscle oxidative capacity and improving cardiovascular function.4 One single bout of HIIT can increase insulin sensitivity and fat oxidation in overweight men.5 Another study proved just how potent HIIT can be. In a 12-week study, total body, abdominal, trunk, visceral fat mass and fat-free mass of young overweight males was assessed after performing high-intensity training. Participants were randomly assigned to either exercise or control group. The intervention group trained three times per week for 20 minutes per session. Aerobic power improved significantly by 15 percent for the exercising group. Exercisers compared to controls lost 4.4 pounds of fat! Abdominal, trunk and visceral fat was also significantly reduced. And on the flip side, they gained lean mass.6 Just one hour of hard training per week proved super effective at changing body composition.
