Walking Forward, Crossing Legs
Straight leg extend forward, cross the standing leg. Close thighs tight. In this exercise, keep hips still, parallel. Do not twist hips. Focus on legs crossing, brushing thighs and feet.
E.g. Start with weight on RF. L leg extend forward cross R leg (not just in one line, but to cross the line). Keep both legs straight. Hip parallel, close thighs. To extend further, lower left side/left hip; feeing like one side pressing down, the other side stretching upward.
Keeping L leg straight while transferring weight onto LF. Trailing free R leg can bend knee a bit while collecting next to L knee and then straighten to cross again with straight R leg

Transfer weight onto straight L leg, free moving leg can bend knee when collecting and then straighten again to cross in the back.
