hi all...need help here.i intend to install a pull-up bar at home. The problem is i can't put it between my door cos my door frame is made of metal. So that place i have to rule out right? The other places i can think of is inside my store room. Those pull-up bars need to screw onto the wall right? Is the ball removable for storage, meaning like take it down when u are not using it? Besides that, do the walls need to be concrete in order to install? I'm sure that will leave "scars" from screwing on the walls right? How about ceramic tiles, is screwing on it possible?
Lastly, where can i get them and roughly how much? Is it reliable, how long will it stay there without dropping or rusting?
Thanks all in advance..really desperate for help cos i cant seem to find any store selling online locally. Thus, i wish to know more reviews before buying.
