How long will muscle memory and strength last if you take time off from training (say 3-6 months)?
The concept of ”Muscle Memory” or neuromuscular conditioning, is basically a form of efficiency developed through practice and repetition similar to any other physical competency.
It is sometimes treated with a kind of superstitious awe as a form of voodoo, presenting some variety of magical property that perhaps will allow the practitioner to go away on a journey to a distant land whose people have never heard of a dumbbell, not lift for years, come back and in a matter of weeks or days get back to their old hulk ways.
The answer to the question of ”how long muscle memory lasts” is that:
It lasts for a while.
