I was doing some beginner gymnastics strength exercises. I saw an advanced video I and couldn't believe what I was seeing.

These advanced gymnasts stood on a box, bent down with straight legs touching their toes, grabbed onto barbell with light weights, keeping their legs straight, slowly stood up keeping the barbell close to their body.

The explanation was the back is designed to do that and if you don't it you lose the ability.

That's not something I would ever attempt, but goes to show if you know what you're doing and have the necessary foundation in strength and flexibility, round back is not only OK but necessary to keep range of motion and strength. Again, I would never attempt that myself.
