You do you.

However, plenty of people with sedentary lifestyles, which includes many who will read this, will have mobility issues that they may not be aware of without coaching. Sure nobody is going to do major damage with the empty bar, but the bar doesn't stay empty.

That said when I say coach I don't mean some random "functional fitness" type that a chain gym will push on you. I mean a powerlifting coach, ideally one who trains people for competition.
