If he can draw a 55 pound bow pretty easily, and the minimum weight is 40 pounds, what's the issue?
Have him get a 45-60 pound bow. I've got issues with both of my shoulders and that's what I just bought last year. A decade ago I had a 70 pound bow and could pull it back easily but started having shoulder pain that would last for 2 to 3 months at a time, so I gave up on archery hunting for a while. But now with this new bow I had it set at 53 pounds and shot it quite a bit over the summer with no issues whatsoever. I didn't end up hunting with it this last season but plan on using it this year. It's especially nice now with 80% let off being legal, I'm only holding 11 pounds when at full draw.I'm thinking I should be able to gradually work myself up to the full 60 pounds if I do it gradually, even if it takes a couple more years I don't care. I just don't want to mess up my shoulders bad enough to where I will need surgery to fix them.
Best thing is to visit a pro shot and have him shoot some bows set at different poundages. do not let him know how much he is pulling though before he tries it, he might surprise himself
Also...keep in mind that it is not how much he can pull......it's how much he can pull and shoot accurately. I pull 65-70 but am a big enough dude that I can practice at that much easily. However, I could kill animals (If i ever get a shot) just as well pulling 20 lbs. less.
Here is another thought, if you find he can pull comfortably in the 50's. You might purchase a 60lb bow and just dial it down to what he can draw. That way he can always go up if he becomes stronger at it. Getting a bow you can dial up or down a bit would be nice and would give you some flexibility... My dad is pulling 60lbs, he is 72 but I could tell this year he was having a little more difficulty with holding it for very long. We will probably dial in down a little for nex year.Good Luck
