60 pounds is definitely a bit too much. And yes you'll have to train hard to gain stability with it. I went all the way to 100 pounds for a bow in 2010/2011 and then dropped back down to the 40-50s. Truthfully, even for me, an avid gym goer, I'm pushing it even at 55 pounds. Hate to admit that but that's the reality with this sport. You gotta train hard to maintain some of these weights.
I'd go with 40 pounds next time around. Even when I train noobs I encourage them to go as light as possible during their beginning year:
20s for females
30s for males.
Yours truly started out with a ridiculously light bow and really there are still form things even I should be working on at the 40 pound range, even though 50 is my optimal draw weight. Realistically, you'll never obtain proper form if you're starting out to heavy. And I've been doing this stuff since 2006 and have hit nearly every draw range along the way.
