The lowdown on low-intensity workouts But lately there’s been a debate about whether this is a good practice. Some people believe that low-intensity exercise for a relatively long period of time doesn't do any good. Their rationale is: in the animal kingdom, there is no such thing as low-intensity, sustained exercise (have you ever seen a monkey in a gym?). They believe that the problem with low-intensity exercise is that it doesn't raise the metabolic rate very much. If you want to raise your metabolic rate significantly, you need to have a high-intensity exercise for a short period of time--like animals do. They chase their prey in short bursts of time and then enjoy the meal and rest for the remainder of the day. Could it be applied to humans? High intensity equals high risk There’s some proof that high-intensity, short-term exercise appears to be better for your body than low-intensity, extended periods of exercise (http://online.wsj.com/article/SB1000142412788732368960457822173001138362...). And according to some researchers, the metabolic rate is going much higher with high-intensity exercise than with low-intensity exercise. High-intensity, short p...
