How does everyone shoot 70+ lbs? I shoot 60 lbs. and I workout 5 days a week and have for twenty+ years now. I shoot almost everyday at least 50 arrows and my draw shoulder starts to get tired and next day just a little sore. I have the new Bowtech insanity which keeps my speed at 296 fps with a 400g arrow and a 28.5" draw so I think I'm good with most big game. I have only been shooting bows for about 2 years now. Should I be shooting with more draw weight?
