Ladies! Chin ups/pull ups

I’m trying to be able to do pull ups too but have ridiculously weedy little arms 😂 I’m building strength through body weight exercises like push ups with different hand positions and chair dips. At my gym we have an assisted pull up machine and I need it to assist 41 of my 48 kg of weight 🤣 I have a long way to go!

I've been doing full-body weight training 3 times a week, 45-60 minutes at a time, for almost exactly 3 months, and use the assisted pullups and dips machine maybe every other trip to the gym. I don't know what rate of progress is average/normal/whatever at this level of commitment so I'll just share my n=1: I've improved by 20 pounds in this time; that is, my weight has been 135 this whole time, I'm eating at maintenance with an attempt to ensure I get enough daily protein, and when I started I was getting a 70-pound assist for 3 sets of 10 reps. I'm currently at a 50-pound assist for the same.

I am a unicorn. I have always been able to pull out a couple of pull ups and chin ups, even after slacking off any exercise at all for a year or being ill in bed with a chest infection.

Are you sure, absolutely certain that the researchers that reinforce the idea that women find these harder than men are not allowing their biases to direct their research.?I mean... Before ww2 white (middle class) women were too delicate for "male" jobs and roles. But in other cultures where the sexes share physical labour more evenly have much more equal sized bodies.

Therefore, I believe a large amount of so called sex differeces are cultural. Feed women and girls less because they're 'delicate' and they will grow up smaller. As they're smaller, they're more delicate and feeble. If this were world wide over all time I would find it easier to believe it has deeper biological roots. But with the above, amongst other arguments, i think it's bunkum! With environment and culture playing a much greater role.

My tip is to practice lowering until that's easier. Then really push yourself to just do it. Make a visual chart. Not on phone, print off for the wall and tick off the three times during the day that you practice.
