Don't push with your heels, pull with your glutes/ hips. To make it easier to understand what you're feeling for, start at the top of the lift first. Clench your butt cheeks and lower down. Lift your toes for greater activation. If you're struggling with activation you could pre exhaust with RDLs and/ or good morning first to get your toosh fired up.
Do single leg and put a finger on the butt cheek that has the leg on the floor,feel how hard it contracts - it fires hard. You want that feeling with a barbell, less weight is more.
If you've ever used a Hip Thrust machine you'd understand, don't ned a lot of weight at all.
We’ve got a 5 year old Yorkie called Bob.
He watches my wife leave for work in the mornings. Sits at the front door and waits for her to get in the car and he’s straight in the bed with me. She won’t have him in the bed.
What a crafty little kunt.
