WHAT IS IT?
Then it depends! When you have been training for a long time and you go on vacation for 2, 3 or even 4 weeks, there is no real loss of muscle mass... it's all in your head! On the other hand, what is inevitable is that you will feel less energetic than usual, since your muscles will no longer be congested like after your training. There are other factors to take into account such as age, generally people under 30 years old lose muscle mass less quickly if the break is longer!
MUSCLE MEMORY
Some people sometimes reassure themselves by saying: "In any case, with muscle memory, I should be back in top shape fairly quickly..." and they are not wrong! However, to be more precise, the muscles do not really have a memory as such, it is rather the result of the fact that the brain has been used to the movements you make during your sessions, so it is rather a motor memory to be correct!
As a result, the muscles that were trained before this long break will return to their optimal state as soon as you return to training regularly.
