Whether it is a fitness instructor or a fitness public, the physical fitness will decline after illness, including athletes.

Physical fitness will not recover after illness and needs to be improved again, which is the main reason why athletes and fitness coaches can't take long holidays. After illness, it should be the same as when you first started fitness or training. Start from scratch! !

Let me give you a suggestion. It's best not to infuse when you are sick. After infusion, your physical fitness will be greatly reduced. Try to take medicine! !
