Chest to wall drill vs Free standing.Two big things have to work for Natarajasana to happen. First is the strength of the back leg kicking past shoulder height for the shoulder rotation to happen safetly. The openness and firing of the hip flexors, quads and pelvis are major contributing factors to the kick

Where the wall helps to articulate dancer is contacting chest to wall (maintain chest to wall) with for the shoulder rotation to get you into position. The wall will help you balance, if you can’t grab the towel with both hands like in the left pic, separate the towel and hold right and left

Kick HARD to striaght your arms and breathe deeply into the resistance

Next steps

Come away from the wall and repeat

You’re Dancing!
