Thanks morrissey, and yes that pull up bar was made for me out of steel pipes. It's simple stuff that anyone who works with steel could build you for rather cheap. Pretty much just cut, and treaded together. I didn't build it though so I don't have the plans.
Chima, i made my own chin up bar from the same material, but mine is bolted into the ceiling of my work out area. That pipe is the steel black pipe and tee's and elbows that you can buy from Lowe's or home depot. it is used for gas lines inside your home and makes excellent pull up stations.
I've seen an exercise routine very similar before, not sure about the chin-up part being included, though. Good stuff.
We also have made ourselves chin-up bars out of plumbing supplies purchased at Lowes, all threaded together and attached with a flange to a 2x4 screwed into the basement ceiling. Wrapped the pipe where gripped with Bike tape. Think I used 1/2" pipe and DH used 3/4"
