So at the end of the summer, after I'd stopped climbing for about 4 months, I remember doing sets of 25+ proper pullups. This is also after hitting the gym consistently for about 4 months. Now that I'm at school I've pretty much reversed it. Been climbing for about 4/5 months and haven't been working out consistently at all. Went to do some pullups today and could barely get to ten . I kind of freaked out. My climbing has been getting a LOT stronger, and I thought there would be some kind of correlation between that and back strength (I thought I'd be able to do 25 pullups no problem because my back has been getting regular workouts) , but it seems I have lost a lot of strength. Any ideas why this might have happened? Aside from being surprised I guess I don't care too much, seeing as my climbing has improved... but it just seems weird that I've improved and yet lost strength?
