There's a reason MP3 players have taken over the gym. One of the best ways to pump up your adrenaline during a workout is to turn up the tunes. Studies have shown that listening to music can actually heighten the flow of your exercises. If you're a runner, then the right music can increase your endurance.
One study found that tracks from Madonna, Red Hot Chili Peppers, Queen and others increased pleasure perception by 10 percent, and it lowered the perception of effort - even when participants were close to physical exhaustion. Loud, upbeat music can help you forget about fatigue and stimulate you to go that extra mile. But match your music to your workout. Slower music lowers muscle tension, so it's best to listen to fast music while weight training.
