I suspect your were probably trying to move your arm sidewise out from under your back rather than extending it towards your feet. The latter is a much stronger motion.I tried bridging but am not as flexible as I would like. I could get my hips and some of my lower back off the ground but my arm was trapped on my upper back
Not really.But would him having two hands on my throat make a difference?
Not so much. He can still move his hands (although that won't help him choke you.) The main effect of the chin tuck (or turtle-necking as I sometimes call it) is that it thickens and strengthens your neck giving more protection for your windpipe and your arteries. That should relieve the pressure enough for you to be able to say "tap" - especially when the guy choking you is only half your size.here's how I would imagine it going: I push my chin down on to the back of his hand and his hand is prevented from moving as it is resting on his other hand.
Would that have happened if I had tried a proper chin tuck?
