Why is daily muscle strengthening activity not recommended?.
ANEK [815]

Daily muscle strengthening activity is not recommended because muscle fibers need to regenerate properly and adapt to physical exertion.

<h3>What is muscle strengthening?</h3>

It is based on a series of exercises designed to work a specific muscle chain or group of muscles, helping to recover the motor qualities of the muscles.

Daily muscle strengthening activity is not recommended since the muscle needs to regenerate and adapt to the following exercise sessions, otherwise the muscle work capacity will be progressively reduced.

Therefore, we can conclude that daily muscle strengthening activity is not recommended because muscle fibers need to regenerate properly and adapt to physical exertion.
