I love these Swiss Ball workouts.
There is a lot you can do with these balls and they really add to the diversity of the exercises.
It is a lot easier to get a targeted ab workout on a Swiss ball, as opposed to lying on the floor.
There is a whole world of exercises that can be done on a swiss ball, that are not available otherwise. This particular move is great for strengthening your core. It’s a bit of an intermediate to advanced movement.
