Interval Training Method

Climb a flight of stairs at a dead run without stopping and by the top you are gasping for breath. Walk a few steps, pause briefly, run a few more, and you can often reach the top faster overall and feel less wrecked doing it. That instinctive pattern — alternating hard effort with a planned, incomplete recovery — is the idea behind the interval method of developing endurance.

The Precise Meaning

The interval method is a structured way of building endurance by alternating a period of work with a period of rest, where the rest is deliberately kept incomplete — the body is not allowed to fully recover before the next work period begins. This is what makes it different from simply resting whenever tired: both the work and the rest are planned in advance.

The Method in Practice

Training continues at a pace sufficient to raise the heart rate to around 180 beats per minute. At that point, a short rest interval follows. Work resumes again once the heart rate has dropped to around 120 to 130 beats per minute, and the cycle repeats. The recovery is short and incomplete on purpose — the next work bout begins while the body is still working through the fatigue of the last one.
