I don't do this a lot currently because all I coach is rec and high school (I have too much variety in skill), but when I was in gymnastics my coach used to make us do NO WOBBLE skills. We never did it with jumps or leaps but with skills that landed one foot at a time (back walkovers, front walkovers, handstands, cartwheels, etc.), and so usually we would have to do say 3-5 either in a row. To do this we had to focus on doing our skills (I don't know if this is a good word for it but its the best I can think of) solidly. meaning our step-down was strong and we had to pull our arms up quickly, not turn out our hips, and get a good lunge at the end. Also, we spent time on corrections (I don't know if this is going to make sense but I will try to explain it the best I can). So say you do a full turn and you are leaning a little to the side, all you have to do is swoop your arm and you are back on easily (it also works for other skills- cartwheels, handstands, etc). From my experience this was one of the most helpful things my coach taught me.
Hope this helps you!
