I suggest some feel good music too. Sometimes I work out to run off frustration but the best part of working out for me is that its just for me!! If I dont want to, I dont have to think about anything else in the world. Listen to songs that pump you up and make you smile. Sometimes I get so into it I catch myself singing out loud, the people at my gym must think Im crazy. I listen to Stevie Wonder, Frankie Valli, Michael Jackson, some Fergie songs are good, UB40....just to name a few.
