High-intensity interval training is just as effective as longer, more traditional exercise techniques.

It has been known for years that 10 one-minute bursts of extremely intense cardiovascular activity, separated by about a minute of down time, provides the same strength and endurance benefits as an hour or more long normal cardio sessions do.

Recently, Canadian researchers monitored students doing high-intensity interval training on regular exercise bikes. The information they gathered suggests that high-intensity interval training will also work at a fast -- but not all-out -- pace.

"No time for exercise is no longer an excuse," said kinesiology professor Martin Gibala, who worked on the study.

Hating exercise, however, is still a very good excuse.
