Hello!! I am a female and have been struggling with pull ups. I have a bar at home and have been attempting to just get one lousy pull up but I struggle so hard.. I'm really good with everything else (besides running lol). My CFA for sit ups was 91 and push ups was 45. Struggled with the mile and the flexed arm hang (because I couldn't do a pull up). Any advice on how to improve pull ups/running!?!?
