I have been hard grinding anatomy for about 3 weeks. I found that looking at other artists anatomy was detrimental for me. I found that many artist either exaggerate the anatomy, don't have a strong understanding of anatomy or simplify the anatomy. I found working off of super muscle pictures of real people with reference helped me a ton. I traced over a ton of Helmut Strebel pictures with the information from Marc in this course and also an anatomy cheat sheet from Cosmic Spectrum I found on her gumroad page for free. Hopefully this helps! Personally I also have terrible memory so I also wrote down the name of each muscle as I traced them as well. Also I am putting out a full muscle practice page when I do my weekly post tomorrow, you might find it helpful.
