Thank you, Rachel, for all of this.

Thanks for your knowledge and experience 🙏🙏 it's very helpful as 🙏 always learning new lesson 🙏

Always looking forward to see Rachel’s videos! I learn so much and I cannot wait to apply it to my own yoga classes.

Great pictures and info for the old biology school re the heart is a pump and understand if you are teaching for your students to pass an exam these old ideas still are in place. But it would be great to research the new biology, 4th phase water, the heart not being a pump. That way we can dispel this old way of thinking and prepare for the new.😊

Thanks for sharing your knowledge. I'm a yoga instructor in Brasil and i am recycling my studies. Researching yoga anatomy on KZfaq i found your channel and it is being of great help with your tips. Hugs from Rio de Janeiro.

Thank you so much for all of your content Rachel. You are so informative and I have loved learning from you. Keep up your great work. Im listening and following from Australia 🇦🇺 xx

As always a very informative talk. Thank you 😊

awesome channel! so glad I found you 😄super helpful videos to inform people's yoga practice and teaching!

Dear Rachel, thank you for your very useful lesson about the circulatory system.....clear, essential. Very interesting the relationship with yoga inversions. 👍🙏

Thanks. I would like to delve into how asanas affect us physically in the circulatory system, nerves, muscles, tendons, fascia, breath. Exactly what is happening to all these systems.

Thanks Rachel - another really useful video. Would love more on the “red tent” discussion both from western anatomical/physiological and yogic energetic perspectives. Over the years, I’ve become uncomfortable with the menstruation yoga prohibitions I was taught. Not because I think menstruation isn’t an issue, but because I don’t know how much is really based on an understanding of menstruation (in all its complexity and individual variation) and how much is based on cultural fear of contamination and misogyny (even in the latter part of the twentieth century doctors in the west were saying women shouldn’t undertake many strength and fitness activities because these MIGHT - no research produced -negatively affect women’s health). Some women are undeniably laid low by their periods, others appear hardly affected - since common menstrual issues include back pain, bloating, fatigue would we as teachers be better directing our efforts to the individual’s symptoms? As for going upside down, l still tell my students it’s not recommended but leave the decision to invert or not up to the individual and like you, I give people a general opt out clause for inversions. Having said that, I have also had the experience of my period being “re-started” when going upside before it completely ended and have read other practitioners saying they’ve had the same experience (just putting it out there, not sure what it means).

Buteyko/McKeown say a higher concentration of CO2 in the blood will more easily release Oxygen from the red blood cells. I was hoping this could be discussed here or in the Anatomy of Breathing. I really like the cautionary tips against inversion but also the encouraging note on its benefits and alternatives. Thank you so much for this content!!
