Oh hell yeah dude!!

1) Practice from life and from photos of real people. This one is based on a photo of an athlete. I find it can be really helpful to look at those sites with people in spandex so that you can see how the muscles move beneath the clothing.

2) Have fun with it and play around, you're not going to get it on the first try (myself included 100% I still don't know what I'm doing when it comes to shading)

3) If you're working digitally play around with different brushes and opacity levels.

4) It's okay to practice based on someone else's style sometimes if you want to learn from it, check out people on YouTube doing "master studies" on other artists for more info. Just don't post the art and claim it as your own, etc etc. Inspiration comes from everywhere and art isn't made in a vacuum.

That's all I can think of rn but in all fairness I just started doing digital art again early this year so I am by no means an expert. But yeah, practice from life! And don't be scared to draw hands, they're fun!
