Coaches,
Which one is the right stretch series to address a weak lower back/hips, and very tight posterior chain in general? If I were to pick only one of the three stretch series, which one would that be? Or do I have to pick and choose different stretches from each series? I really need the focus to be on fixing the lower back issue before the other courses can be considered on a longer term.
Also, maybe I'll post this in the Foundation forum, but which strength exercises are the best for strengthening the overall posterior chain?
I really appreciate an answer and thank you in advance!
