The above summery is quite correct about hip alignment.
It's not correct to say more demands and the situation get worse not better. It depends on whether exercise postures, movement patterns,and muscle balance are increasing incorrect movements or postures or reducing them.

Ie exercising in a way that tends to promote internal rotation at the hip may alter the situation in a positive way.

I would get your leg length properly checked for a start.

Additional exercise is not the most critical aspect in altering posture. We sleep for 8 hours. We sit most of our waking life.............
