- High-intensity interval training (HIIT) gives a natural boost to human growth hormone (HGH) production, which is essential for optimal health, strength and vigor. HIIT has also been shown to significantly improve insulin sensitivity, boost fat loss, and increase muscle growth
- According to Japanese research, a mere four minutes of exercise performed at extreme intensity, four times a week, can improve your anaerobic capacity by 28 percent, and your VO2 max and maximal aerobic power by 15 percent in as little as six weeks
- Study participants who performed an hour of steady cardiovascular exercise on a stationary bike five times a week only improved VO2 max by 10 percent, and their regimen had no effect on their anaerobic capacity after six weeks
- Previous research showed that just three minutes of HIIT per week for four weeks improved participants’ insulin sensitivity by an average of 24 percent
