like brighteyes said do the rows in the corner, usualy most people will take the close grip seated row handle to row with. this is good personally since i jsut started lifting at home iw anted a tbar, instead of paying for a actualy t bar i bought this
http://www.bigfitness.com/bolatblbar.html just slide it on the end and either buy the platform to put the other end of the bar in or just do corner rows you be fine either way. i know your lifting in the gym but if u wanna buy that it will be like a real tbar. i can put it on in a second just slide it on and screw with your hand. yeah u would have to take that to the gym everytime so its proly just beter to use a seated row handle like most people
