Muscle soreness after workoutCreated by:
After participating in some kind of strenuous physical activity, particularly something new to your body, it is common to experience muscle soreness.
Exercise physiologists refer to the gradually increasing discomfort that occurs between 24 and 48 hours after activity as delayed onset muscle soreness (DOMS), and occurs when the muscle is performing an eccentric or a lengthening contraction. Examples of this would be running downhill or the lengthening portion of a bicep curl.
No one is immune to muscle soreness. Exercise neophytes and body builders alike experience delayed onset muscle soreness.
The big problem is with people that aren't very fit and go out and try these things; they get all excited to start a new class and the instructors don't tell them that they might get sore.
To them they might feel very sore, and because they aren't familiar with it, they might worry that they've hurt themselves. Then they won't want to do it again.
Letting them know it's OK to be sore may help them work through that first few days without being discouraged.
