You're correct. Calling it a 'stretch' is misleading. It's more of a 'release'. After many years of sitting, the hip muscles tighten, atrophy, and lose their ability to rotate the hip. The hip stays tight (flexed) and the thigh muscles (and others) end up taking over the role of keeping your body upright. This works, but stresses these muscles, since they weren't designed for it. This stretch (or release) convinces the thigh to 'let go' of your hip, allowing it to rotate. This has positive effects all the way up your body, especially in the load-bearing joints: ankles, knees, hips, shoulders. In severe cases, you might need to wait a very long time for this release. My right thigh takes about 40 minutes to release completely. I use the flexing thigh test he describes in the video to know when it's done. I've been doing it every morning for a week now and can sit upright without pain for the whole day, something I've never been able to do before. I'm looking forward to continued progress!
