From how I’m envisioning this, the width of your arms/hands is of great concern to me. Frankly, after some time of this uneven positioning you could develop a pesky injury- if not in your hands directly, possibly in the arms, shoulders or neck. In weight bearing postures for the arms, the entire hand- palm, heel and fingers alike- must press firmly and evenly down on the mat. Therefore, if you are lifting up off an uneven surface, the weight is not equally distributed thus, leading injury. It’s funny how these small habits we develop can be more detrimental.
Now, in response to the width of your hands/arms. The proximity of your hands/arms from the trunk of your body, is crucial in creating stability, strength and control. The further away, the less control. With your hands/arms being so wide from your trunk, you are making jumping back more challenging. Pulling the torso through the gate of the arms takes a tremendous amount of strength, both in the abdomen and the arms. Bandha engagement pays a huge role too. Also, counter balancing is an element.
I’d suggest trying a few things. First, bring your hands close enough so that the entire hand is on the mat. Next, work on hugging the knees closer together and into the body. Kathryn Budig calls it making yourself a “tight little package.” Lastly, play with counter balancing some. Just like learning bhujapidasana or bakasana, work on rocking the weight forward while pressing firmly into your hands in preparation of “shooting” back and through the arms. This will give you some (controlled) momentum and help getting you through the arms in closer proximity.
One more thing- pay attention to how you are distributing weight in your hands. Often times we favor the the outer edge (the pinky edge) which will encourage the palm to pocket up off the mat. Again, this is taking the weight away from the trunk of the body when in fact we want to draw strength from it. So, if notice you do this work on pressing the L of the pointer finger and thumb down to the mat, engaging the inseam of the arms. This will help tremendously in controlling movement.
Happy practice!
