If you can bench 120, you can definitely yank back 50lbs!!! It will just take a little time. Hang in there and each week put about a 1/2 cranck on each limb. By the fall you will be pulling 50 with your teeth!!

Welcome aboard. Don't get discouraged!!! The first few years can be tough!!! I've been there, took me 3 seasons to kill my first and have gotten one every year since then going on 14 years!!!
