Hi there, you've already received some excellent advice but the only thing that leapt to my mind as I watched your vid was 'why not practice finding the groove with face-the-wall squats?'

That said, I'm no expert like the other correspondents so my question is really directed at them as much as yourself - what do you guys reckon? Would wall squats be suitable to help increase the lower back flexibility that the Dr. pointed out on his YouTube commentary? Or are wall squats different to such a degree that their particular groove wouldn't help?

Eager to find out.
