What I’ve seen about bracing/neutral spine from McGill makes me wonder about two things:
when I’m in any functional sports environment (especially, say, bump skiing or hockey), I feel I need to adopt a posterior tilt (until approx “flat lumbar”) to break the connection between legs and torso so the legs & hips can act independently. The amount of force applied/absorbed by the legs/hips on skates or skis is tremendous - and so, hopefully, I’m protecting my lumbar spine by absorbing the force there via independent leg action.
Also, to some extent, I do end up carrying this same position (flat lumber/pelvis tilted under) over to my unsupported, one-legged squats.
Does this make any sense or am I putting my lumber spine at risk? Any comments appreciated. Thanks so much & cheers!
