Interval training Pros and Cons

Interval training is a fairly new and well-researched exercise. The technique switches between stints of high- and low-intensity exercise.


What’s good about interval training says Brad Schoenfeld, certified strength and conditioning specialist and author of the book 28-Day Body Shapeover (Human Kinetics, 2005), is that "Intervals increase calorie expenditure and afterburn, so calories are burned [even] after the exercise is over." This is supported by a research from the University of Guelph, which shows that interval exercises burn more fat and improve fitness quicker than moderate and constant exercise.


On the downside though, Schoenfeld admits that high-intensity intervals can be tough and even dangerous for people with injuries and disorders, and advises that exercisers check with their doctor first before trying out any exercise. Cathy Lang, a Chicago-based certified trainer, adds that "There’s no social aspect to motivate you; you have to tap into the competitor inside."
