sPL/PE1 and FL/PE1 form checks

Hi.  I just want to make sure I am doing these exercises properly as I absolutely do not want to develop bad habits.  I am planning to submit regular form checks as I want to do Foundation by the book - this time!

For shrugs: nice rom, engage your posterior pelvic tilt now, for better result in the nearly future.

Hinge rows: also here, engage your posterior pelvic tilt at the bottom of the rep.

I see exactly what you are referring to.  I will get it corrected!  Thank you.
