Hi Carson[
],
Good to hear life is treating you alright. I'm happy for you.
In upward dog,it's just the back of the feet that are typically touching the ground, as Victor pointed out, and the feet and legs are also spaced apart,not together. In cobra the pubis , (and therefore the legs onwards)swadistahana chakra ideally touches the ground.
But i agree with you engaging the back muscles and using the legs for leverage assist with the back bend and relying less on efforting with the arms. The bhujangasana i practice the arms can assist with the posture, and yeah sure there is a cobra where the arms are not employed at all.
If you could'nt use some effort with the arms, it could be too much for the lower back.
I have started practicing it this way-
I just engage the parapspinal/lower back muscles as i begin to initiate the movement,legs & feet together,then the arms slightly placed forward and bent can begin to assist with the back bend.But the bentness of the arms as isay can depend on high or how much of a backbend,i.e how flexible, the student is capable of.
Also i think Victor is right when if the body is 'nt open or flexible enough then it is a lot wiser to modify the pose than try to aim for an idealised posture.Sound Alignement must also be paired with appropriate actions, otherwise you risk yourself an injury.
I think it's a pose that probably is'nt taught in classes enough,because too many instructors teahc a kind of flow yang yoga where you don't spend quite enough time in a pose or entering and exiting it to actually be able to sense what is going on internally.Therefore i think alot of these kinds of classes are missing something.
This is , to me
updog Urdhva Mukha Svanasana.
It is just semantics, but the legs touching the ground ideally all the way to the the pubis is one type of cobra. Another which i've been told is part of the traditional hatha(old-fashioned )sun salutations where the legs and the toes are touching the ground and the lower buttock and hips are also to the floor.Unless the spine is very flexible the arms will remain slightly bent.
I'll quote you relevant portion of text you from a book i've got- a respected authority-'Asana,Pranayam,Mudra &Bandha' one version of bhujangasana-
Bhujangasana (cobra pose)
"Slowly raise the head neck and h shoulders.Strightening the elbows, raise the trunk as high a possible.
Use the back muscles more than the arm muscles.
Be aware of using the back muscles first while starting to raise the trunk.Then use the arm muscles to raise the trunk further to arch the back.Gnetly tilt the head backwards so that the chin points forward and the back of the neck is compressed.In the final position the pubic bone remains in contact with the ground and the navel is rasied to a maximum of 3cm.If teh navel is raised too high the bend tends to be in the knees and not the back.The arms may or may not be straight.This depends on the flexibility of the back...If that was urdvha mukha svanasana in the video i posted here,i would expect both to see:-
1) the legs suspended off the ground, & the back of the feet resting on the ground
& 2) & the also legs slightly apart. I have observed in students quite varying distances from really wide apart to somewhat less.
And i don't see that.
This naming confusion that probably plasters the internet, because i remember researching it a while back ,obviously helps no one.Confusion between Upward dog and cobra is probably the biggest one out there.
Victor- i'm with you ;it's just semantics.And as for King Cobra,well that sounds like a version of Cobra to me,given that it is more of a back-bend and the hips are in touch with ground-not so with urdha Urdhva Mukha Svanasana.
