overreaching

Functional overreaching is essentially short-term overtraining where you have a goal of digging yourself into a recovery ditch. Two weeks—two ball-busting weeks. Get to work and reap the benefits.

In order for you to progress you must overload. But you can't increase all variables at once, or you will run into trouble. Learn the signs of overreaching and how to avoid overtraining.
