Great piece! Great videos. Three years ago at the start of the pandemic my knees hurt so bad I walked with a limp at age 47. I was so scared I wouldn't be able to enjoy my favorite activities. The Docs did nothing. No suggestions on lifestyle changes with exercises or diet. They just ran my bills up with visits to "specialists." With the help of my girlfriend I did all the right things and am back to myself. Eliminating dairy was a game changer and then doing these types of little exercises helped immensely. Strengthening my glutes to help my overall posture helped too. A little goes a long way. I plan to write a detailed piece about all this. I also became conscious of the way I sat at my desk, how I sat in my car, and how I stand when in the kitchen making food. Our everyday postures can be hurting us too. Again...great piece.
