What do you guys think about this DIY pull up bar kit. It can be easily made from my understanding. I'm also wanting to know opinions on just putting a steel pipe across one of those one piece fiberglass shower/tub stalls. It would go the length of the tub and rest atop where the stall sticks out of the wall. It seems pretty sturdy there. I'm actually wondering about how much the pipe could support and would I have any problems with breaking.
