Loon,
I've been a regular gym goer and amateur power-lifter for over 12 years without any off-time long enough to mention. The longest break I've ever taken from powerlifting was the 13 weeks of Marine Corps recruit training. I'm still pretty young at 28 which also helps. I shoot Hill style. More squared up to the target, 28" draw to the corner of my mouth with a 1 second release/no hold at full draw. Split vision.
I shot archery throughout my childhood and picked it back up hardcore after the Marine Corps. Started back up with a 50 pound FG recurve, then 55 FG, then discovered self bows thanks to Primitive Archer and made a 60# board bow. Following was a series of other self bows around 60.. then 65.. then 75.. then an 85 that broke at a fade after a while, and just for fun a 105# trilam that I abandoned due to excessive hand shock. Now I'm working on a 90+- to begin training with for hunting. I always grab either my 75# hickory or 74# Osage cuz they're my sweetest shooters, but I'd go heavier if I had one on the shelf at the moment.
Even coming from a decade+ of powerlifting, it took me three years to progress from 50 draw to 100#. It takes consciously working up your draw weights and shooting as often as possible. I was already very strong by traditional gym standards, but it took training to transfer that strength to archery since nothing in the gym simulates pulling 90# to your face, lol. If you're set on shooting heavy weight bows... build up in 5-10# increments and shoot, shoot, shoot.
