Get yourself in a life like hunting situation at a challenging 3D course. Not only is it good exercise during the offseason, its a great way to work on yardage guesstimating and delivering a shot that counts. Convince yourself that each shot is that one big shot that you have been waiting for. Good 3D courses will also open your eyes to how incline and decline shots can send your arrow off its mark if you’re not shooting properly. Practice makes perfect!
