Calisthenics Unity

Over the summer i will be travelling somewhere in a family member's house which is isolated in the mountains, and there are a few bars there yet they are pretty thick, is there anything i can do to make it easier for pullups? They are pretty high bars as well.

Thanks :)

When you have very thick bar it's good to put your thumb over the bar but it's my opinion maybe someone will have better advice :)

Kinda what Przemek said, try to get your hands as far over the bar as you can, without it hurting or feeling too weird of course.
