I like Katy Perry's Roar and Firework... they get me going, and sometimes I put them on to get me through the last bit of running as well. Some people might find her a little too teeny boppery, but whatever gets you going.

I like What You know (2 door cinema club), Starry Eyed Surprise (Paul Oakenfield) and when I am feeling like I really need to get the stress out I like old punk from the 70's/80's like the Damned, Sex Pistols, etc. The Damned are probably my all time favorite work out band. Some of their early stuff has the perfect beat for exercising but it is an acquired taste.
Love me some Pendulum.
I don't really know if they count as "rock" but they are definitely a group that will get you up and going.
My happy Pandora station for busting out workouts or for muscling through loads of deskwork is Zed with Pendulum added in as variety. Then Pandora (of course) mixes in a bunch of other great music as well.
I liked the 80's pop- Paula Abdul, Cyndi Lauper, Oh, Mickey Your So Fine, Wham, Madonna, any of the 80's club music.
And for giggles for warm up there is always The Chicken Dance. It starts off slow and builds.
Oh, well, clearly you're not thoroughly indoctrinated to COTH yet, because finger pointing and drawing conclusions are the cornerstones of this great online community. (Tidy Rabbit)
I have a lot of different music on my workout playlist:
And We Danced - Hooters
Wake Me Up Before You Go Go
Back in Black
( I like to mix it up)
