It is normal for many people to feel muscle pain the next day after fitness. Moreover, pain means effectiveness. It shows that the training has reached its due intensity. If you don't feel anything the next day after training, it basically has no effect.

This kind of pain is called delayed muscle pain, which is a normal phenomenon. If you feel painful and it is not effective to continue exercising, then you can slow down a little and rest for a few days before continuing exercising.

Or exchange different positions for exercise. For example, some people just started to exercise their arms, and the next day it hurts. Then the third day can be transformed into exercising leg strength or waist and abdomen strength. Don't start exercising until your arm recovers.

And according to our past experience, it is usually the first time, and it will be particularly painful when the strength is restored. As long as you keep normal training later, you won't feel so painful anymore.

If it is very, very painful and the pain is abnormal, it may be caused by overtraining. Or there are some inappropriate actions in the training process, causing sports injuries.

If this happens, you must stop training immediately and seek medical advice in time. Sports injuries can be large or small, some of which can be recovered after a few days' rest, but in some cases, if not handled in time, it will lead to a series of follow-up problems.

For people who have just started fitness exercise, it must be gradual. Fitness is also an urgent matter, even if you run on the treadmill for three hours every day, you can't achieve the effect of slimming and shaping at once.

This process needs to be accumulated slowly, so that the body can change slowly, in order to achieve the purpose of fitness.
