This one is very challenging for me in so many aspects. Just to push

up into it is hard and yesterday I was even grunting while pushing

up.

 

What are the muscles that need to strengthen in order for one to push

up into this pose?

 

Also, once I get up, if I can find the strength to continue pushing

up and perhaps begin to get my shoulderblades into my back a bit, I

finally feel a little stretching in the abdomen area, which I think

is correct. But I'm not feeling much of a stretch in the chest area.

Do the abs need to be stretched out of tightness before I can get

into the chest stretching?

 

Thanks!
