Hey there,
From the technique videos I didn't understand fully if I should maintain a PPT through out the whole exercise or only at the beginning, then switching to APT.
In addition, from the front split stretch series, I understood that one should maintain an APT to enhance hamstrings stretch and also put less stress on your lower back. Would this mean that JCurls will stress my lower back (by doing PPT)?
Thanks,
Feli
Note: I had some small disc protuberance 4 years ago. So far so good.
