Thank you so much for sharing your advice and personal feelings on this pose. I am practicing alone, sometimes my boyfriend is around so he spots me occasionally. I do feel flexible enough in both shoulders and arms, and I feel my wrists and forearms are strong enough.. Maybe it's a mental block that's holding me back. When I do actually manage to push up (with help) it feels sort of unnatural (?) even though I would love to feel comfortable in the pose. I guess I just have to work on strengthening and lengthening (even more!) but am determined to master the pose.
