Time to Build Up More Muscles

One thing I've been wanting to do for quite some time now is bow-hunting. Only thing is, to hunt anything of a reasonable size and take it out humanely without too much suffering, I have to be able to pull 40 lbs bare minimum, preferably 45 or 50 lbs. So I decided to try my hand at a 45 lb compound bow, not realizing that unlike a recurve or a longbow, the compound bow is very hard to pull initially and then it's easy to hold up at draw length. I'm used to a recurve, where it's easy to pull and then the real effort is in holding the pull. I can pull 35 lbs reasonably well on a recurve without suffering too much and 40 lbs is doable but my aim suffers and I do have to rest periodically... as for 45... well, let me tell you what happened... Having a bit of an ego, I decide to try my hand on a 45 lb compound bow. I try to pull and my face is turning red and I'm straining pretty hard to get it to move. All the while, the store-keeper (who knows me pretty well since I've gone to hunter safety training and generally get the bulk of my archery supplies form there) is wincing and grinning at the same time.

The recommendations when I asked about different compound bow models and technical specs?

1) Shoot more! A lot more, even if it is on a lighter bow!
2) If I can't go shooting, then go weight-training.
3) Go for one of the more aggressive bows by Bowtech (www.bowtecharchery.com) after I can comfortably pull a recurve about 5-10 lbs heavier than my intended compound weight.

So yeah... I'm kinda sore from attempting to pull that 45 lb compound bow today. Oh, it didn't quite help that my ego drove me to try something else kinda stupid at the archery shop today. I tried shooting a nice 45 lb take-down recurve. I was able to do it with a fair bit of effort just to prove to myself that I'm not a weakling. Let's just say that's as much as I'm able to pull safely without killing myself. As if that weren't enough, I actually do shoot a few arrows with it and sure enough, my aim sucks. Ouch. Here I am now, wishing that I had someone to give me a nice shoulder massage after these acts of ego-driven idiocy!
