For me, it's pretty simple: the better the playlist, the better the workout. I use music to hype me up and push through, and Justin Timberlake is often what it takes to make it through the last five minutes of a workout. If a song has the right balance of beats per minute, I'm suddenly moving on the elliptical harder and faster than I thought possible.
Trainer Jackie Warner feels the same way, too. She recently shared a playlist with Shape, saying that changing up your tunes is a huge way to stay motivated. Here's what Jackie is listening to lately; it's a nice blend of high-energy pop and hip-hop — guaranteed to make you sweat!
