Hi Kristen, like you I am working my way up to at least 40# draw weight. I have a take down bow for which I purchased 35, 40 and 45# limbs. I am currently practicing with the 35# limbs after working on my form with a 30# bow I have. I bought, on line, resistance bands to exercise with; inserting the medium band inside the xtra heavy band to increase “draw weight.” I plan to keep moving up with the resistance bands until I can comfortably draw the heavier weight limbs. Good luck to you.
