I chose this reference footage because it is a nice transition from leaping into a cartwheel type motion into a flip, which can show one movement flowing into another. I have attempted to animate a character doing a flip before so I also have some experience in knowing how the movement works, although my previous attempts were not as good as the one I created.

I animated this animation first by creating a key every 8 frames, using stepped keyframes. Once I got the poses mostly how they would be in the final animation, I further added keyframes on every 4 frames between the previous keyframes, as creating every 8 frames did not show off the full movement very well. I started by focusing mainly on the position of the waist and legs, later moving the arms and hands too. After I finished creating the stepped animation I converted it to splines, and fixed issues such as rotating hands too far, or the knee and elbow controlled making the arms and legs move strangely. I went into the animation graph editor and cleaned up the curves to make sure there were no strange shapes. After this I further refined the animation and fixed issues such as the movement not happening in a very straight line, as well as the knees popping at certain times in the animation.
