You shouldn't feel a stretch. It's not a stretching exercise.
It's about obtaining compression (active flexibility) for your press to handstands, and it's a core exercise so you had better feel it in your abs.
If you need stretching, you need to work that in conjection with this. If you need CORE work, it's best to use active flexibility work for that. Which is why I suggested this -- it's a mobility drill but a different kind than you're used to.
