Back on the subject..

The gym I go to plays a lot of AC/DC which is awesome.
They also have the random techno/trance sort of stuff which is also great when your using the rope or just about anything where you get into a rhythm.

I can't think of any certain songs though.. I'll just put a good album on and go for it.

Actually no..

Hells Bells & Back in Black - AC/DC get me totally pumped!
