Everyone has given good advice. My 2 cents is do a couple of sprints or pushups or both before getting behind your weapon to practice. It will get your heart rate and breathing up and teach you how to manage both when shooting. Once you get good with your bow and gun add this to your training. It makes a huge difference. It took me about 8 years of hunting to learn deer and sign and what it all means. I still learn tons every season.
