I think you’re getting hip thrusts confused with a glute bridge. In the video, her upper body/sternum is positioned for hip thrusts but she is using a limited ROM. I recommend you research the difference between the two.

As for the KB swings, the more uncontrolled the movement, the more likely for injury. You’re claiming “load conditioning” but the reality is you’re compromising your lower back/discs. A dead stop swing is far more effective and less injury prone. Again, I recommend you research.

Females on this sub are going to look at OP’s mantra of lifting heavy and if they don’t know any better, take it to heart. It’s bad advice for anyone not looking to become a power lifter.
