A memory is what is left when something happens and does not completely unhappen.
If your legs are strong it definitely gives you an advantage coming down hill. As far as specific workouts go, I get a kick out of sled pulls and driving the sled. I put a couple of 45 pound weights on it and just go until I can't feel my VMO muscles (Vastus Medialis Oblique. ) That's the muscle right next to your knee, on the inside.
