Will this hurt my back?

Will this hurt my back?
My bf says I need to workout and get a bigger butt.

she is pretty hyperextended so maybe, that exercise is safe with a neutral spine though.

nah just keep your chest up so you dont round your back

Its like a good morning and squat.

If you dont have a massive arch in your back, sure, but barbell squats, deadlifts and other squat variations works better.

Just do hip thrusts

...

I'm generally in favor of exercises that isolate glutes more, personally if a girl tells me she wants a bigger butt I don't want to give her a ton of heavy compounds that will give her legs a bulky shape.

i think your bf should like your butt the way it is. is it normal or tiny

aka use the machine how its intended to be used and stop being a whore for likes

bulky legs= hourglas shape

your argument is invalid
