Hey im looking to buy a pullup/dip tower, I believe its called a POWER TOWER. I've seen one that I liked, its called IRONMAN POWER TOWER. The only problem is that its ~87 inches in height and my ceiling goes up to 99 inches. Im worried that this might not be enough space to complete a full pull up and not have to worry bout banging my head against the ceiling, as it only leaves about 12 inches of space.

BTW here is a photo of the tower:

Physically you've got the room--no problem. I have the same height restrictions at my place. The trouble I find is getting past the MENTAL hurdle. I'm always "thinking" about hitting my head (although I never do). It means I don't put everything into the lift that I could.

You should be able to do a pullup just fine, imo. I think a foot is plenty.

i guess it depends on how far up u go...i usually go where my throat meets my chest
