Bar balance foot position.
When you’re starting out, try to have the foot as straight along the bar as you can. No twisting at all. The other leg will try to stay parallel to it and *Not* in front or behind because this will lead to you trying to balance with a twisted body and hips. Let start with everything being straight and perfect first.
Sorry for the twisted camera angle, was tricky balancing and holding the phone at the same time!
