This is my neutral spine in bottom- so you can see a little space under where my lumbar spine is 

Movement itself looks good! Personally I prefer to keep my spine neutral in the bottom position- but this is a personal preference thing. Maybe something to play with- because it translates over to hinge work better that way 

If the box is moving- it against a stable surface or use a weight behind it so it stays in place. Also make sure you’re pressing down onto the box- that should help too

Very good ! Great control!

Or split squats but you might want to hurt me after doing these 😂 https://youtube.com/shorts/DFKQVe5EeC4?si=M103peck3Maz1Mmp

Oooh or if you have a smith machine you can try these https://youtube.com/shorts/pBGmi9A1LLU?si=IpmA6ID8FrnVRQBw

Ooooh. Do you have a leg press machine? If so you can do a glute biased press on there. You can use a barbell for hip thrusts but time/ effort/ stability issues make it not my favorite. You can post a video of the set up you try and I can give you feedback or you can try glute biased leg press 👍🏼

Both look great overall! If you wanted to be picky- you could work on improving your neutral spine position in bent over rows- think more hip flexion so you get your lumbar curve neutral… and you could control bottom position of presses more 👍🏼👍🏼

Very nice 🤩🤩🤩

Movement looks fine it still looks too light though. What do you feel?
