FL/PE15 (Negative front pull)

I've observed that sometimes my elbows bend just a little bit, specially at the end repetition of the series on the Negative Front Pull FL/PE 15.
Should I stick to 100% straightened elbow and isometrically tightened straight arm all the time?

And move to the next progression if all the criteria are met, like:

• posterior pelvic tilt, no arch, glutes, legs, abs engaged
• isometrically tightened straight arm all the time
• at least 3 secs descending, no less
• shoulders depressed and partially protracted

Thx for the answer in advance.

Hey Botond, yes locked are necessary. if not is possible to develop inner/outer elbows problem.

@Alessandro Mainente That is what I thought exactly  thank for the answer.
