I dont know of the breathing helped, but your warning helped, because I brought tissues up next to my mat.
I didn't realize how much work she was going to have us do in those lunges and how long we would be holding them. That was harder than I thought. I like how you used to find her getting distracted by the sand butterfly adorable, but now you're like damn it Andrea shut up about the turtles and let me put my ####### arms down.
I am excited to say I did my best crow ever and was actually up there for a second or so. The big change came when I put my hands at shoulder width/pushup width instead of putting them too close together.
If I understand correctly, the things you want are a big flat base from your hands, your wrists and forearms making two columns straight in the air, full width of your shoulder or even wider. Your knees should be up into your armpit/bicep area, but it's really your shins that are going to sit on the flat back of your arm, just inside where your shoulders are. So the weight of your knees is on your upper arms and your arms are pressing straight down the vertical forearm so the only strength is keeping your wrists tight and your legs from falling off your arms, but the majority of your weight is held up by your bone, not muscle.
I might not be understanding correctly though. I am not a yoga instructor and this is not yoga advice. Consult your doctor before beginning this or any exercise program.
