Hard to be nimble

For many times in the past, I’ve tried make a model perform a back flip but I can never get it right. I’ve tried studying it and matching it but I can never get it to land correctly. Any one has any ideas on how to execute it?

What is the problem with landing ? You may give us some more precisions.
I think, usually the legs needs to be set in IK before taking off, then FK during the jump, then IK again from landing.

Well, it was more on the part of bringing the legs back as it gets ready to get back on its feet. But I manage to get it to flip another way.

Now my problem is how to make move smoother than the video above.

Never mind, I got it. I erased some key frames and now it’s not so choppy.
