When initially working out, why are you getting stronger but not building any visible muscle?
In: Biology
When for example doing bicep curls with a weight that is a big challenging for you it will actually make small tares in your biceps’s muscle fibres and once you finish working out your body repairs those tares but like with scar tissue when you body repairs your muscles it adds a bit more on than before so that in future doing the same activity will be easier
Your nervous system is less efficient to begin with, so you can’t use your muscles to their full potential. After you’ve trained for a while, your strength increases due to the increased neuromuscular efficiency, but your muscles haven’t actually needed to get any bigger yet.
Your muscles are quite strong even if they are not very big. A problem when not using your muscles for heavy lifting is that your nervous system will arange itself to have more dexterity and less strength. Basically the nerves will not connect directly to a big part of your muscle which allows for finer control but makes it hard to get a lot of strength. When you start working out the nerves will grow new connections allowing you to use more of the strength in the muscle. It is possible to measure the strength of a muscle by attaching electrodes and send a strong electric pulse through the muscle. Even trained athletes will not be able to use their full strength but can get very close.

Eat more protein .. muscle building is a slow process so initially it’s not easy to see a difference.. if they don’t have the building blocks to grow then you will still gain strength but not size .. or it will be an even slower process .. intensity of workout also plays a major role .. for example prison inmates gain size over time even with their small amount of protein intake .. because they workout intensely .. all of this is majorly simplified though many other things affect muscle size such as testosterone and genetics
