So I thought I wanted to drop weight. My "go to" bow is 60#'s. Well, 60# @ 27", I draw 26", but when I replaced the grip, written underneath was 60# + 3, so I'm guessing that puts me right back at 60# for my beloved Wesley Special.
Now, 60# is not necessarily "heavy" by some subjective standards but I consider it, for all intents and purposes, to be "heavier than neccessary" for most of my practical hunting. So I picked up a 50# bow to use as a comfortable shooter. But honestly, and this is not bravado, my release is less clean with the lighter bow. I don't hold at anchor long, just enough to set my anchor point, and the heavier bow "pops" out of my release smoother it seems.
Of course, I could condition myself to the lighter bow, (and one day I may just have to!), but with regular shooting and my regular strength training I feel like building strength (in my physical condition) is more practical than dropping weight.
Bent over single arm rows, pull ups, and inverted rows are easy to progress with, safe to perform, and can be done with a variety of on-hand equipment.
I fully understand the physical limitations of people, old age, injuries, etc. and I am in no way advocating going up or keeping high weight in these situations, but if you do have a bow you love, and you're physically capable of progressing in strength, make a dedicated plan and you'll be surprised at just what advantages the heavier bow weights can do for you.
