StepMania as exercise

Hello everyone,

I want to start using StepMania as an exercise routine. I've read that StepMania used to have a workout feature, I take it that version 5 no longer has it.
Also, any suggestions on good workout song packs?

Thanks in advance!

Ones that are geared towards more Pad use than Keyboard would be better IMO. I'm a long fan of DDR from the PS2 (still have my setup) and it was great cardio!
