I can shoot in my shop, but it's only 6 - 7 yards. Sure beats not shooting, though.
We do have an indoor range not far from here, but it's hard to get my buds together to shoot as they are mostly still working.
As I get older, I find myself getting weaker and have dropped bow weight about as far as I can and still hunt, so this winter I decided to start Terry's workout/up regimen. I'm drawing my heaviest bow (only 46#) and holding for 5 seconds. I do 5 reps and then switch sides. Do it every other day, twice a day. Once I get up to where I can do 10 reps each side, I will buy or borrow a 50# bow and work my way up in reps on that one.
I'm totally comfortable hunting with a mid-40 # bow, but if I can work my way back up to 50#, that sure can't hurt. Gettin' old is a bear :(
