Even nowadays at the start of my leg workouts I start with it, nothing activates glute max in isolation like that, in particular when your extended knee is bended.
Instead of hamstring curls, I suggest you to see the variants of glute/hamstring raise move for reasons.
Weakness in core normally activates frontal upper body muscles more than back. If you want to train only one group between your chest and back, I recommend back (not lower back and lumbar spine). In all those crawling and stuff you are training chest muscles anyway. Again inchworm push ups, chest move.
I personally would incorporate huge changes to this program.
