I have different symptoms with many friends around me who exercise all the year round (including those who are almost 50 years old), but they are all mild, and there is almost no case of getting up and moving after lying at home for a few days. Generally, the symptoms are mild, or come quickly, come heavily, but go quickly.

If you want to resume fitness, you must arrange it according to your physical condition, step by step. I can only test my body to gradually increase my strength and ability. It is not recommended to practice every day. I think it's better to practice for a while. I only did a little capacity and strength in the early stage of recovery. If there is nothing abnormal in your body after you go back, take a day off and add a little capacity and strength. Once you regain your physical strength, you can't wait to restore your former strength and ability. This is death.
