bhekasana confusion

so ive been given bhekasana for a few months now, and while i feel some improvements ie i can lift my chest a little more from the ground. However, it has overall been a struggle. I'm not sure how to put it in words, but I feel like im fighting against my different limbs; my arms are trying to push down my legs but they wont really budge, and on the other hand im also trying to lift up my chest. if anyone knows what I mean. Where should I work on first? any advice or even experience would be amazing thanks!!
