There's a popular belief that a gym workout is only effective when it causes muscle soreness the next day, giving rise to the expression "no pain, no gain." However, science questions this widely spread idea in gyms.

Science explains what muscle soreness really means and what are the mechanisms behind this sensation. The text promises to clarify when muscle soreness is normal and when it should be a cause for concern for those who train.
