Hello.
During the TBS trap stretch where one rolls back onto his shoulders and his knees (ideally) come to the floor, I'm experiencing my wind pipe almost closing. It feels like a hose with a kink. A very similar feeling as to when I would roll in BJJ and my opponent in my guard would "stack" me, back on to my neck and shoulders. I would lose my breath and have to tap.
Any ideas why this is happening and what I can do to fix it? I don't experience the "kink" if I avoid trying to achieve a good depth. I can breath fine with my knees rocked back a bit (feet not even close to the ground), but this also does not allow me to feel any stretch in the neck/traps.
My only thought, embarrassing as it is, is that I have a little too much girth through the midsection (around 20% bf), which is constricting my breathing...
Thanks.
