I'm trying to do pull ups more frequently, and it would be more convenient for me if I was capable of doing them at home. I'm not allowed to use the pull up bars that attach to the door, because the door frames in our house are not in the best condition, and there's concern that I would mess them up worse.
I know I can get a pull up dip station for $50-100 off of craigslist, but since I can't fit it in the house, I would need to store it in the backyard. Does anybody have any experience doing this? I'm concerned that having it sit outside all year may mess it up. Would putting a cover over it be enough to protect it (for the most part)?
