Hi there,

I am digging the WW program but I have 2 questions: one theoretical and one practical.

Theoretical question:
In the spinal flexion/extension/rotation exercises in WW intermediate one bends and twists the spine simultaneously. This spinal torsion is said to be "bad" by many "authorities". It works great for me and gets the kinks out very well but, to explain it to others I would like more logic to back it up than that "it feels great; try it you'll like it." My explanation is threefold:
1) It is torsion, but with no added load so the spine is strong enough to handle it if it's largely healthy.
2) It gets the kinks out because it moves the spine in ways that it doesn't get moved often.
3) Torsion happens in daily life so it's important to train for some "unsafe" movements and ROM so that you can deal with them when they pop up.
Any comments on all this?

Practical question:
I like WW and joint mobility exercises in general for greasing me up and getting my energy going in the AM. However, I find that doing the 4 corner balance drill at the end of WW does the opposite for me. It is static and seems to tire me out a bit, brings my energy back down, and tightens my hip flexors up pretty good when done. I have to do some more dynamic stretches, especially for my hip flexors and glutes after the 4CBD to counteract this sort of tiring/de-energizing effect. It is the only exercise in WW that does this to me.
So, any comments on this one?

Thanks very much for your time. You guys rock!
