I actually just had a 110 lbs chick in a competition shooting class. She had tiny hands and was running a big glock 34. I advised her the same as I advise a 300 lbs man. Stand comfortably squared up to the targets, have your shoulders in front of your hips (do not have an aggressive forward lean, just a forward weight bias). She was able to make center hits on a 7 yard target while shooting as fast as she could manipulate the trigger.
I have experimented many times with using my body position to try to minimize the effects of recoil. I have really played around with it SHO (where I feel recoil control is a big issue) by leaning way forward and such… I have never actually been able to produce observable and repeatable improvements (as measured by a shot timer) by leaning far forward.
