This is definately a very common problem. And the thing I think I did to fix it was to spot my landing, before I wasn't really looking what I was doing so I would just randomly land and fall back. But when you spot the landing, you are ready to land before you hit the ground. Another couple of things to remember:
-Lead with your head
-Keep your whole body together
-Make sure you are spinning fast enough for the amount of air you have
