The cramping is right up under my ribcage. I am not sure if it’s my diaphragm – deep breaths don’t seem to affect it – but it’s in that location. It stops when I straighten my back.
It happens in standing separate leg head to knee, after a few seconds with my forehead on my knee. But if I do that pose, and get the cramping, it also happens in rabbit and even sometimes in head to knee stretching. My leg is quite bent in that pose, my hamstrings are not very flexible.
I think I can avoid it by not trying to straighten the front leg and just letting my head rest a bit lower rather than trying to curve forward so much. That’s not really doing the pose properly, but I think it’s the actual forward compression that isn’t working for me right now.
I haven’t been doing anything else to stop it from happening.
