Title isn't completely accurate, as the author states they were kneeling bent-over, creating an incline for the food to travel up. That being said, I've never thought of the esophagus was a muscle that could be trained. Very cool!

Edit: there's a 6" riser that the author describes kneeling on, while their head is then lowered closer to the floor, supported by their arm(s).

Maybe I should try this. I've been having trouble with this lately.

>The incline is established by kneeling with the head bowed lower than the stomach

Shouldn't it be upside down if the head is below the center of mass?

I think this would be one way to describe upside down, but my feeling is I wasn't the only one picturing someone fully inverted with feet above head.
