First, start with the same drill as you’d do to start learning a back walkover, a bridge with one leg up:
- Push up to a bridge, and lift one of your legs as high as you can.
- Work up to a position where you can lift your leg so it points straight up to the ceiling. This will help you learn how to balance with support from only one leg and your hands, and improves your flexibility too.
- Practice lifting each of your legs. Though you will most likely do a front walkover with the same leg supporting you each time, it's still helpful to be able to do this drill each way.
