How many of you guys build up muscle memory to hold your bow back as long as possible? When I first started doing this I could last 2 minutes and 30 seconds and that was in February. By September I was up to 11 minutes. This was 4 years ago and since I haven't kept up with it so I decided to start up again and 4 minutes was my starting time. What's the longest hold you've had to wait for a shot in the feild?
