You should start at a lower poundage like maybe the min for bowhunting weight here it is 45 lbs. Then as you gradually get stronger you will want to pul more. The advantage of pulling more weight is that you have a flatter arrow trajectory and more KE(kinetic energy) or hitting power. I have been shooting for 6 years and am now drawing 70 pound back, im 17, 6'1, 200 lbs. If you try to pull to much to early it will greatly sacrifice form and you will get worse acuracy than with lighter poundage.
