I am learning glute bridges and hip thrusts. I saw a couple of videos mention that lumbar spine should be slightly posteriorly tilted at glute bridges and hip thrusts. Is this movement pattern safe?
My concern is I have never kept my lower spine in slightly posterior tilt on my main lifts(deadlift, squat). Learning different lower spine movement pattern will affect my main lifts and cause lower spine injury while deadlifting and squatting because I got used to neutral spine.
