I don't very much know the technical aspects of a V-sit, but it seems like there is one thing that I personally have a problem with.
On top of the abdominal aspect of the position, there is a need to press the hips forward. I can't do that, and it seems like that is my biggest trouble spot. But I also don't have much knowledge on the position other than it seems like the shoulders are allowed to lean back to compensate for balance while the hips are pressed past the hands.
If someone can help enlighten me on the strength involved throughout the different aspects of the v-sit. And cramps are extremely unpleasant and they seem to be more common while attempting this, how can I get rid of those?
