This month's workout playlist is full of surprises. Jay Sean and Nicki Minaj's "2012" came out months ago, but the New Year (and an apt title) has given it a second wind. Maroon 5 and Christina Aguilera received a hip-hop makeover, courtesy of Mac Miller. Outasight got their first taste of chart success. And Adele's performances have been so fierce that no one seems to mind that her song is more of a ballad than a traditional workout jam.
