Alternative To Stall Bars And Horse?

For those of us working out at "normal" gyms - what are some good alternative tools / equipment / methods for the PEs and iMs that require stall bars and the horse (as in the back extension stuff eg: Straddle running man)

 

I know a smith machine can be used for some of the "lower" stall bar stuff but I have a hard time with the HLL exercises (in general).

Thanks for the ideas - and actually I thought this WAS the F1 forum! woops.  

OK I have found the real one now and will post related questions there in future.
