I tried doing the 90/90 hip mobility exercise every day for two weeks and now I can squat and lunge without pain

A woman performs a 90/90 hip mobility exercise, with both knees bent at 90°, her left knee in front and her right knee out to the right side.

After the birth of my son, the two exercises I struggled with the most were squats and lunges.

My hips were tight, my form felt off, and no matter what adjustments I made, I still felt pain during the movements.
