It's SCIENCE!

Like every red-blooded American, I made a New Year's "intention" to get into better shape and take on a healthier lifestyle. Sometimes, a good tune is all you need to get ya goin'!

You can trust this playlist (???) to do just that, because it was put together by scientists...based on beats per minute (BPM) and how they match up with what activity you're doing.

For instance:

Warm-up/Cool-down: Pop music

Jogging: Rap

Lifting Weights: Dance music

Here are the very specific examples of what they call the "ultimate playlist", from warm-up to cool-down:

1.  To get mentally prepared and psyched up . . . listen to "Roar" by Katy Perry.  It has 92 beats per minute.

2.  While you're stretching, "Talk Dirty" by Jason Derulo. 100 beats per minute.

3.  For an aerobic warm-up, "Get Lucky" by Daft Punk.  116 beats per minute.

4.  For a moderate cardio workout, "Timber" by Pitbull and Ke$ha.  130 beats per minute.

5.  For a more intense cardio workout, "Applause" by Lady Gaga.  140 beats per minute.

6.  For REALLY intense cardio, "Can't Hold Us" by Macklemore and Ryan Lewis.  147 beats per minute.

7.  For weight lifting, "The Monster" by Eminem and Rihanna.  110 beats per minute.  (Which isn't really "dance" music, but the other examples they gave were British.)

8.  And to cool down, "Burn" by Ellie Goulding.  86 beats per minute.

When it's a REALLY tough workout, you're also supposed to choose songs that remind you of your YOUTH, because they subconsciously help motivate you to power through when you're tired.
