Turk, if you're struggling to pull back , you're probably over-bowed. It's amazing what a difference 5 or so pounds can make. Besides what David said about injuries, all the gyrations will only make it harder to draw back undetected. You will gain strength as you shoot more, but work up to higher poundage. Although IMO, high poundage is not necessary these days. Many bows will shoot plenty fast at 60 or less pounds.
