After the season, I will pack up the bow for a little while, but during the winter I might pull it back out an shoot in the basement. From corner to corner, I can get 20 yds., but I have to put the basement ion "lock down" mode so no one comes in during my practice.
During the summer, I set up a couple of bag targets (30 & 40 yds.) in the back yard and shoot from my elevated deck (about 15'). I don't put in long sessions, but I do shoot 4 -5 times a week for 15 minutes. I will increase the frequency as the season gets closer, but I actually shoot fewer arrows/session really concentrating form. When it gets to October, I put out a buck target and will shoot only 1 arrow/session with the theory that I will only get 1 shot and no warm ups when the season starts.
