Any thoughts on the super deep, low position that some times results in the "dreaded rounded back lifting" posture? Essentially, making contact at toe level might require either an super deep Oly squat at the knees, or a silly-deep stiff-leg deadlift position, or a bit of lower back flexion.
I suppose some treads might allow a grip point higher than ground level. I'm thinking about tires that basically require grip at ground level.
Best,
Mark
