Lower the weight down to at leather 185 and work for 5 sets of 5 don’t add a single pound until all 25 reps are generally correct. Your rounding over in my opinion because one you are allowing the weight to shit to your toes and lower back weakness. Make sure your keeping weight on the heels of your feet personally depth does not look to bad your just trying to turn into a good morning same problem I had before. Do this and with in a month you should be looking better in the squat.
Good Mornings 4x12 (these are not a Max effort lift do not reach failure)
Hip Thrust 4x20 (start with bodyweight hold for one at top)
Weighted Planks x 3 x 30sec ( I say 30 seconds because you want to increase core strength specific to equating and 30 sec is about right)
Squat 185 (5lbs added if all reps following week were satisfactory)
Hip Thrust 4x20
Weighted Sit Ups 4x20
