There's no guarantee of this. It's quite possible that muscle and bone cells require the stress of weight loading to develop properly and that there's no simple hack to make them do it without that response.

Even beyond that, there's a bunch of neuromuscular training needed to deploy the muscle properly!

When you first start lifting, your 1 rep max is limited by your ability to recruit muscular functional units simultaneously (and in the correct order) to complete the movement. I forget the real number but an untrained person will be able to recruit maybe 1/3rd of the muscle they have for a 1RM movement.

Keyboard ticklers - get out there and use that meat! I mean it!
