The ability to flex my foot has not changed. What has changed is my balance and learning to move and walk with my whole body — rather than just drag my foot along as I used to. The sensation in my foot essentially remains the same but there are certain poses, adjustments, alignment, etc. that increases the sensation. And of course, when I put my mind there I can increase the sensation.
For the past three years I have only been practicing Iyengar. I take classes from 3 different teachers regularly at the same studio. I had tried other styles of hatha yoga but there was always too much forward bending and flowing from one pose to the next. The alignment and precision in Iyengar was a perfect fit. As I began to align my body everything got better!
