First of all, you should have a certain muscle quality, otherwise you will be too thin, and even if you turn into black charcoal, you will not feel a sense of muscle.

We know that bodybuilders usually try their best to make their skin dark, because black always gives people a tough feeling. After being oiled, black skin will better reflect light and make muscles beautiful. Of course, it also has the function of highlighting muscle contours, but this is not the main reason.

If you want to have a muscular outline, you must have developed muscles, even if the skin is very white, it will show up. Black just makes people feel that the other person's muscles are strong.

I have been working out for two years, and I have summed up this truth.
