VERY tight!

I have some serious work to do. It has never been an issue till just 3 months ago. How bad???? When I lay on my back and pull my thighs to my chest, my legs are bent almost FORTY FIVE degrees! Even waaaaaaaay back when I played High School Baseball in 1984 and 85, my Coach was AAAAAANAL about pre practice and game stretching. Even then, when I was a nimble / skinny teen, I was stiff. Well, at 54......It has bitten me in the a$$!
