Different interpretations I believe.
The question was asking about a supplemental program based on an activity level and specific sports, namely weight training and running. As to the inquiry about “form” I can’t determine from that if the question is about yoga flavors. If that’s the case then the reply would be one outlining different types of yoga and how they might serve practitioners.
That having ben said …
It seems the reply was more of a dissertation on one way to come into one asana. Which frankly isn’t a partially deveopled answer let alone a fully developed one.
In addition the original thread is entitled “new to yoga” and an instruction to “be mindful to keep your chest open” might be a good instruction in some instances but it’s quite vague for a beginner and can lead to both misconception and misalignment.
Asaana for beginners (and some intermediates too; from a teaching perspective) are instructed from the foundation up. There’s no real mention of hands and feet in this reply so I’m not sure I could call it “sound” with a clear conscience.
That’s why I wondered, aloud, if the Rocky was reading or just posting around the site for web hits.
