I enjoyed them, but something really sad happened. I asked one of the trainers who the "hack squat expert" is in the house, to see if they could check my form. She checks around, and one of the guys said, "Oh yeah, the machine's in the back by the plate row machine." (Misunderstanding the question).
I said, "No, I'm using a barbell, I just want someone to check my form and make sure I've got it down."
"I have no idea about that," he said. I died a little on the inside. But pretty sure I did them well, everything felt clean and I'm tight where I'm supposed to be tight.
