If you’re short on time, but still want to get your cardio workout in, high-intensity interval training gives you some of the same benefits of long-distance or long-duration “steady-state” cardio exercise (e.g. jogging on treadmill), and in less time. Studies have shown that this short-burst type of training (with adequate rest periods between each exercise burst) improved the exerciser’s aerobic endurance capacity.
But, an additional wonderful benefit will be that on a “per unit of time” basis, you’ll be burning more calories as well! So, short on time? Now you don’t have to let that deter you from getting your cardio exercise and burning those calories!
A WORD OF CAUTION: Because interval training is a higher-intensity exercise, and requires a planned “work-to-rest” pattern, you should ALWAYS check with your physician before attempting interval training, AND consult with a Certified Personal Trainer for help on developing the program that’s right for you.
