There has been much hype about some recent marketing attempts by higher profile yoga teachers lately with respect to the use of 'Yoga for Weight Loss' as a branding tool or theme. I thought I would pipe into this conversation briefly with a little perspective on both sides of the debate.
Gravity can be defined as the agent that gives weight to objects with mass and causes them to fall to the ground when dropped. In the context of yoga, gravity provides the medium in which we can exert force, generate strength, and root against to form poses. By understanding the basic principle of 'lines' of gravity, we can be more effective in our approach to alignment, exertion, and pose formation.
