Years ago, I used to work out in the gym several times a week. My regimen was first and foremost, I would always warm up before any workout doing some sort of cardiovascular exercise, usually the treadmill. Then it was, upper body one day, skip a day, lower body next day, skip a day. My breakthrough came when I started measuring my progress by keeping a journal.
So, theoretically you could take that same procedure and apply it to an archery workout. Always warm up first, work on form one day, skip a day, next day work on distance, and skip a day, next day work on accuracy, and so on, and so on. Keep a journal.
As far as accuracy goes, I would relate that to having six pack abs. Have you ever seen these ads that claim to give you a six pack by doing this one thing, or taking this one pill. Having well defined abdominal muscles are a byproduct of your whole body being in very, very good shape, along with proper nutrition, and diet. Accuracy is a byproduct of everything coming together at once, you can’t have one without the other, period!
Hope this helps!
