After doing a weighted pike with around 35lbs, with a flat back, I felt that my back was a little worn out, as in a dull pain at the very bottom of my vertebrate. I just want to ask is this normal? If isn't a sharp pain at all, but more of a mild/dull one. Is this typical for all weighted pike stretches? However after I did a few unweighted pikes, the dull pain almost completely diminished. Perhaps it could be because of trying to hard to keep a straight back?
I'll post a video tomorrow showing my form.
