When you're out of the home, whether at the gym, or driving your car, or sitting on a bus, take that time to make use of it. Instead of listening to distasteful music (i.e. pornography for your ears) which corrupts your soul, try to listen to something beneficial in your cd/phone/mp3 player! You could listen to Quran or even some lectures to increase you in knowledge, insha'Allah! Reap those good deeds!
