The first thing that you want to do when beginning the process of a cartwheel on Pivot Animations is face right in a walking position. This means the left arm is bent and the right arm slightly bent in front of them and the left leg is straight behind and the right leg is in front slightly bent. Then you make the figure take two steps while bending down and using their two feet to jump off the floor into the air. Then make it so that their body is flipping in the air and lands parallel to the floor with their legs in the air and hands on the ground (hand stand position). If you do all of this correctly it should look like this:
Once you are in this position on make it look like you are jumping off the floor with your hands and into the air. While you are in the air you have to be flipping to the right in the air while landing straight on your feet. When you land you must land the rite side up with your hands in the air coming down to your sides. At the end you can add a little flavor by doing a bow or jumping up into the air landing in a split. If you do this correctly this how it should look like from the point you saw before:
This the final product of all the hard work with a little flavor that I added:
