I hate to be a party pooper (actually, I don't), but if your sleep is poor, you need to look inside yourself and calm your mind down. In the long run, exercising a lot won't compensate. You want to enter another world, not keep processing the daytime world.
Turn your phone off, do only non-stressful things and don't eat before bed, cover up all clocks in your bedroom, and yes, meditate. That's how you sleep better.
