I have dropped nearly 20lbs by eating less, walking 2 miles and biking 2 miles daily. I also lift very light weights with high reps 3 times weekly.
I can shoot in my basement when it is too hot or too cold. In the basement I can only shoot about 8 yards though.
When shooting, I like to shoot 1 arrow at a time from various spots, angles and distances. For some reason I shoot better if I know I am just shooting that 1 arrow. I am sure it is a subconscious thing. I also shoot 3D as much as possible since that is my end goal(hunting). My deer target(vital area and front leg) is really hurting right now. Not much left.
I always end on a perfect shot, regardless of distance required to get it. Finally, I only shoot 12-20 shots so I don't get tired and can focus on form.
I am not Rick Welch, but I do okay. I just need to stop shaking when a live critter comes along I plan to shoot! Even a squirrel....go figure.
Oh yeah, I make sure at least one shot is 60-70 yards because it is fun. Do that enough times, even one shot at a time, and you will be suprised how often you hit where you want.
