definently take er easy for a while. when drawing a bow, you use alot of muscles that arent used for much else in everyday life. when you feel yourself getting tired hang the bow up. shooting tired leads to bad form and bad habits that are tough to break. if your overly tired to start, lower draw weight and take a break for a couple days till your rested up. no problem with working upto your desired weight...just dont push yourself too hard...injuries can ruin whole seasons and come quick if you arent careful...
