congrats on your new adventure!! It would be wise to take the bow to a pro shop and make sure the draw length fits you first, and is set up right for you. It may have been set up for him but may need a few changes to fit you, such as draw length, peep sight placement, length of arrows, draw weight and so on. they can also show you how to properly grip the bow and help you with your form. after this you can work on your shooting. good luck this season and hav fun!!
