Fit as a Fiddle (max Health) and Ironheart (max Stamina) each need one stat raised all the way, and 126 Inhibitors aren't enough for both. So: with at least 81 Inhibitors unspent, back up the save outside the game, max Health, restore the backup, then max Stamina. Do the three rows below back to back: anything you pick up or finish between the backup and the restore is undone when you restore. Trophies you earn in between stay earned. If the backup won't restore on your platform, keep the save with Health maxed, put every Inhibitor left into Stamina, and finish Stamina in New Game+ with its 30 extra Inhibitors. That fallback has limits: only one of those 30 spots is known (section 22), the rest have to be found by searching, and it needs every one of the 126 from run 1 too.
