Backflip Animation

I did a animation of the rig doing a backflip. I learnt that during animation, you can use key poses for different body parts, rather than having all body parts in a position for specific key frames. This gives a more fluid looking animation. For example: the torso could be animated on key frame 1-10, where the arms may be on 1-5-10. This may seem like something obvious, but as someone self teaching, its something ive only really just learnt.
