Interval training has become very popular these days, thanks to high-intensity interval training, or HIIT. Proponents of this type of exercise say it delivers many of the benefits of a much longer workout in a short, sharp burst.
The great thing about intervals is that you can do them with pretty much any type of exercise, including running, swimming and cycling. Interval training is also ideal for indoor workouts, like the cardio machines at your local gym. Or you can get creative and mix things up with a jump rope or weights.
