The weight is arbitrary. If you can't physically move whatever weight without proper form and regardless of the movement it probably isn't the best idea to do so.Not quite the same. You can't short press 300#s and live thru it. You can easily get the "70@28" bow and draw it as far as you can to exercise your drawing muscles... to perhaps the 50-55# draw length. That is a very quick, easy, safe and efficient way to reach your goal of properly shooting a heavier bow.
How ironic.....I am suggesting the best way to do it because I have done it. I gave my experience on how to be able to safely and very affectively shoot a heavy trad bow..... with 30 years later of more strength and healthier shoulders to boot.
Since you guys have your bow weight increase method down pat, tell us all how you guys have moved up from 25-30#s to your 70-75# trad bows. Tell us about your actual experience of how you moved up in bow weight to that heavy injury causing bow you warn about because surely you have or you wouldn't be telling us how. We'll wait.
Don't shoot 70. Don't have much of a desire to. Started at 25, then 40 and then settled in at 50 which I think meets just about all of the requirements in NA.
If I'm going to pick up a bow, it is going to be with the intention to execute a good shot which is more accessible working with a comfortable draw weight as opposed to being over bowed.
