Let's be real for a second: For many of us, there are a lot more reasons not to work out than there are to hit the gym. Maybe you're too busy today, maybe you're too tired, maybe you'd just rather spend your afternoon hanging with friends or binge-watching something on Netflix. Whatever the reason, it can sometimes take a fully-planned, well-thought-out motivational tour de force just to get us off the couch and into the gym. So, with that in mind, it's a good idea to give yourself all the ammunition you need to get out there and work out.

As any music lover can tell you, no supplement on the market can get your blood flowing quite like an intense, motivational soundtrack of all time classics pumping through your earbuds. Leave the slow jams and jazz classics at home, because in the gym, your attitude should be clear and simple: Turn down for what?!? Year after year, there are a ton of new songs to get fit to, but it’s hard to beat the biggest hits that have withstood the test of time and gotten people moving since they first hit the airwaves however many years ago.

These tracks can really help you get the most out of a workout, driving you to push harder and set new PRs in the process. Instead of relying on Pandora (and it's flow-interrupting ads if you don't pay for the premium service) or that playlist you hastily dumped onto your phone five minutes before leaving the house, take some time to find what will really spark your fire and keep you going, no matter how long you're in the gym, on the track, or doing pushups in your bedroom. To get things started, we combed through dozens of our favorites to bring you the best workout songs of all time.
