In plain English

If you train too much, your performance can drop and stay low for months — and even after you recover, you won’t get any stronger or faster.

See the scientific wording

Overtraining results in a prolonged decrease in physical performance that requires months to recover from, with no subsequent performance improvements despite recovery.

What the research says

2 studies

  1. Study: Overtraining in Resistance Exercise: An Exploratory Systematic Review and Methodological Appraisal of the Literature

    The study looked at overtraining in weightlifting and found that while performance can drop temporarily, there's no strong proof it stays low for months or never gets better after rest.

  2. Study: Prevention, diagnosis, and treatment of the overtraining syndrome: joint consensus statement of the European College of Sport Science and the American College of Sports Medicine.

    The study agrees that overtraining syndrome causes a long-term drop in performance, but it does not say that an athlete can never improve their performance again after they have recovered.
