Your body is malluable and adapts to your everyday needs in a certain range, but always tries to use the least amount of energy.
If you need muscles because you use them, the muscles will grow to use energy more efficiently, but if you don’t use them, they chrink back because even the maintenance uses energy.
Like having a huge engine a car it is fuel efficient because it is efficient on high power output, but if you are only use it close to idle, that would consume more fuel than a smaller engine at it’s most efficient usecase
