The first part of Pain Free explains how muscular imbalances form and, most insightful to me, how every human body has the same design range of motion (with a few exceptions due to birth defects or disease), that is every human body is designed to have the same range of motion but muscular imbalances formed as the result of specific repeated activities (or lack of activity) impede that design range of motion. All of the exercises in the Egoscue Method require no special equipment, only simple things like a chair or a wall (which further convinced me that it's not a fad out to sell something). Highly recommend reading these books if you're interested in this topic.

What exercises did you find most beneficial for strengthening?
On a related note -- I periodically do stretches where I stand on one leg and roll my hip & waist out to the side extending it behind me -- that helps alleviate tension in the side.
Similar - hanging on my forearms from chairs or those ab machines at the gym.

It gives you a set of targeted exercises depending on your self-diagnosis. His secret weapon is the 'Supine Groin Stretch', shown here: https://www.youtube.com/watch?v=uXYQWFkVTDI. I recommend trying it at least once. The stretch opened my eyes to how my body should and could feel.
Pete’s knowledge completely rewrote the way I think about my body, pain, and imbalance.
