What are your favourite workout songs?

On my MP3, I have a mix of Cake, Portishead, Queen, Violent Femmes, Red Hot Chili Peppers, Blur, Scissor Sisters, The Beautiful South, Paul Weller, Tori Amos. Cool down...Aimee Mann (Magnolia), Morcheeba, Leonard Cohen, Jeff Buckley.

I need to add more. Some great recommendations from others on this thread!

Scissor Sisters, Scissor Sisters, Scissor Sisters!

....with a little T Rex, Oukast, Pipettes, Led Zeppelin, Jet, Iggy Pop, David Bowie, and Franz Ferdinand thrown into the mix.

But seriously, just try not to jump on to that treadmill when "Tits on the Radio" comes on - I dare you!

fitpod I tend to use..although it may be techno it's got a good pace so it motivates you to walk or run. They have from walking , to yoga , to aerobics podcast you can use. The best part that it's podcast are free so you get 30min to 1hr of block sessions. Avoid the thrash metal fitpodcast...ugh.

Scissor Sisters is a must!
