The understanding of anatomy

I have slowly been building on my art skills and understanding for most of my life,but I hit a stone wall when i decided I wanted to get into character creation thus I begin my study into anatomy. I must say it has been nothing short of difficult saying this I continue on with it and hope to make way sooner or later. I'm yet to get a good source of learning it's mostly been pieced together by tips and videos though im slowly getting there or so I think and so very desperately hope.
