Answer:

You must wait at least 24 hours.

Explanation:

One of the reasons to take a break after a workout by lifting very heavy weights is the muscular hypertrophy, that is, the growth of the muscles, happens precisely in the rest period

In the process of developing the muscle we break the muscle fibers and form new, stronger and more resistant. This path that generates hypertrophy begins in the training, but consolidates in the rest period.

For example, if you have lifted heavy weights and your arms are sore, wait at least 24 hours for a new workout that focuses on this area. At the time, enjoy working other parts of the body such as legs and buttocks.
