Take a look at women's bows or even youth bows for older kids. They usually have both shorter draws and lighter weight. Women's bows do come in colors other than pink camo.
About 18 mo ago, I messed up my right rotator cuff (I'm right handed). I'd had physical therapy on my shoulder that didn't help much. I hadn't shot in 10 or 15 years but wanted to get back into it. I dug my old bow out of mothballs and started to find out what my shoulder would allow me to do. My bow only goes down to 60lb while 55 would be better but I'm handling it ok. Amazingly, shooting has helped my shoulder far more than the therapy did. I shoot maybe 15 or 20 arrows several times a day. My shoulder's feeling better than is has for over a year. Apparently it's just the exercise I needed to do.
