Interval Training Motivational Quotes

And if you can tolerate it, a minute’s worth of maximal exercise, in the form of three all-out sprints for twenty seconds each can change your physiology as much as fifty minutes of cycling at a moderate pace. Studies from my lab have demonstrated all these things. The naysayers warn that high-intensity intervals are only for people who are really fit and really motivated. But those naysayers are wrong. Listen: Some people shouldn’t perform interval training. But it’s a rather limited group, and many more—even those with chronic diseases—can benefit from an interval-based approach to fitness.

When it comes to cardiovascular exercise, the general guidelines recommend doing between 20 and 60 minutes. However, this will depend on the intensity of the exercise you are doing. Steady state low intensity cardio, such as walking on a treadmill, can be done for up to an hour at a time. In contrast, high intensity interval training (HIIT), which involves short sprints followed by even shorter rest intervals, should only last for a maximum of 20 minutes.
