I practice year round. I shoot a couple of times a week all of the time shooting from 25 to 50 arrows. A couple of months before hunting season, I start shooting every other day. I shoot both from the ground and from a tree stand. Practice sessions should vary from shooter to shooter. When you start getting tired and your groups begin to spread out, stop. As time goes on, the amount of arrows you can shoot effectively will increase. I also strongly recommend shooting a few 3-D's before hunting season, if possible.
