You're a multitasking maven. (We bet you're reading this while scarfing down a snack and scanning your PDA.) So why isn't your workout doing double time?

Engage your brain and body with iMinds, a series of 8-minute podcasts packed with perfect dinner party fodder. Choose from 12 categories including politics, travel, pop culture and history, and download tracks to your iPod or MP3 player. With more than 180 podcasts available at $0.95 a pop, there's sure to be something that strikes your fancy.

During a morning run, we huffed and puffed to fascinating tracks about Mt. Everest, Joan of Arc, crop circles and Stockholm syndrome. And unlike other podcasts, we could follow the info easily thanks to the faint background music and crisp British accents.

Get it here or download from the audiobooks section of iTunes.

You'll be sharper and slimmer after your sweat session.

It's elementary, my dear.
