Ever run a marathon? I have completed 10 and from my perspective, they are brutal. Very difficult. Very challenging and do little for fat loss or overall improvement to the cardiorespiratory system.
What about a 2 hours workout in the gym? Who has the time. . . .
Fortunately, neither is needed to help you burn fat.
Sports scientists at Canada’s McMaster University found that just three 20 second sprints at full effort provide the same improvement to your cardiorespiratory system as much as 50 minutes of cardio/exercise. Additionally, overall muscular-skeletal strength also improved.
Just 3 sessions a week was enough to improve overall health and wellness and contribute to fat (weight) loss.
