I am running up a stupid, crazy hill. It is 92 degrees. I am sweating. Actually, no, I'm not sweating -- I'm seeping sweat. I have two miles left in this godforsaken 15-miler (oh, marathon training in the summer!). And my iPod Shuffle has just clicked to the next track. On repeat in my head: Pleasebeagoodsong, pleasebeagoodsong, pleasebeagoodsong.
Happens to you every workout, right? There's a reason for it too. SELF talked to researchers from Keele University in England and found that when you cue jams you really love (vs. songs you're so over, or music from genres you dislike), you move faster and push harder during your workouts. And while yes, it's super easy to recycle that go-to playlist every time you work out, to really rev your mojo and burn you've got to ditch the songs you used to adore and move on to new aural obsessions.
SELF has 100 ways to do just that. For our July issue, we polled hundreds of readers, top trainers, pro athletes and staffers for their No. 1 crush-that-session song and created the ultimate playlist from the top hundred. You'll see a little bit of everything -- sugary pop, badass hip-hop, clap-happy indie, and even country -- and I guarantee you'll find something that makes you want to move right now. I've loaded them all on my Shuffle, and I'm always psyched to hear what's next.
