Eccentric Muscle Contractions and Soreness

The video explains why muscles get sore after intense workouts, focusing on Delayed Onset Muscle Soreness (DOMS). It describes how eccentric contractions, where muscles lengthen while contracting, cause tension and minute tears, leading to soreness. Examples include lowering a dumbbell and squatting. The video concludes with a call to action for viewers to guess the next video title.
