- How well balanced you are in the stance
- How wide the stance is (Glutes positions determine this, Ex - Both glutes exteneded = A wider stance)
- The direction (if any) your momentum is causing you to lean into.
- Which direction your chest is rotated

The direction your chest is rotated is a big factor, because if you want to actually make a twist, or even jump successfully, you'll need to have it rotated in the opposite direction you want it to go when you first start out in the horse stance. Even partially rotated still works.

Now, there's different types of jumps from the horse stance, but the most basic jump that almost anyone can do is simply :
-Extend the pec of the arm that has the opposite direction the chest is rotating in (Right rotate = Left pec --> Extend) and contract the pec that is in the same direction of the rotation (Right rotate = Right pec ---> Contract)
-Extend the hip that is in the opposite direction the chest is rotating (Right rotate = Left hip ---> Extend / Left rotate = Right hip ---> Extend)
Once the arm that has the contracted pec is in front of you, you know that you're ready to jump.
From here, there are many different options. However, again, I'll be telling you how to do the most basic jump. So :
- Extend the hip that is in the same direction your chest is rotating (Right rotate = Right hip ---> Extend / Left Rotate = Left Hip ---> Extend)
- Extend or relax (Depends on the situation, just play with relaxing or extending and see which fits best) the knee on the same leg (The one just stated)

- Raise both shoulders
Optional and sometimes necessary - Sometimes, you'll need to contract both glutes. But, this is optional if you want to do something else.
Side notes - Don't forget to mess around with your lumbar. If you're leaning too much on one side, try to see if playing around with the lumbar will fix your situation.
Also, make sure you have the unneeded joints relaxed (Except the neck, keep your neck held at all times)

And, to add the cherry on top, here's an example replay of the basic jump I just explained. I also added in some different types of twists you can make out of the horse stance.
Practice is key, bro.
