So what is interval training? It is short intervals of time during your exercise that you really turn up the intensity. For example, if you are running on a treadmill, and your speed is 5mph (or 5.0), you might jack it up to 7mph for 1 minute intervals. So 1 minute of high intensity and 3 minutes of a normal pace (5.0). If you ran for 40 minutes total that would be 10 intervals of 1 minute each.
If you just ran for 40 minutes at 5.0, that would still be good but you would not get the afterburn effect of interval training (see yesterdays post).
