I’ve always heard that when working out the muscles in your body tear and come back stronger than before. If it’s just a tear can’t you manipulate the muscles to tear it without working out?
In: Biology
You can. You can pass a mild electric current through the skin to the muscle which makes it contract and simulate exercise. It’s not exactly comfortable though. There are lots of commercially available products that do exactly this
It’s not really tears in the way we would normally consider a tear like a piece of paper. It’s microtears throughout the muscles that, hopefully if the working out is going well, comes back harder stronger faster better.
