Students who do not often do strength exercises, occasionally do strength exercises, may have delayed muscle soreness, that is, muscle soreness after exercise (24-48 hours). Under normal circumstances, symptoms can last for 3-5 days, and will not cause harm to the body except muscle aches.

To prevent the occurrence of delayed muscle soreness, we should pay attention to the following points: (1) The amount of exercise should be gradually increased, and some room can be left at the beginning; Once you start practicing, you must stick to it; Stretch and relax muscles in time after exercise. Don't be nervous even if you have delayed muscle soreness. Reduce the amount of exercise appropriately and stick to it. As long as the interval is not too long (more than a week), muscle pain will not appear again if you continue to practice.
