Relocate pivot point in imported blender model

I made a simple block humanoid in Blender and imported the .blender file in Unity. When i add it on my scene, its transform point does not coincide with the actual model's location. So when i try to Rotate my model, it doesn't just rotate, it also moves in a circular pattern because its perceived axis of rotation (as far as i can tell) passes through the transform's location and not the actual model's center of mass/gravity.

Is there a way to get the transform at the center of the model's torso or something without parenting it to another object?

P.S.: I tried messing around with the model in Blender but the result stays the same.

 

In Blender you can do Object -> Set Origin -> Origin to Center of Mass. Also make sure you save and maybe reimport the model.

Alternatively, you could do it in ProBuilder using the "Center Pivot" feature.

 

Recentering the origin to the geometry's center of mass fixed it.

Thank you very much!
