Weight plates (gym) on upper floor?

[crillux]

The boy wishes for a barbell and weight plates to train at home, and there is currently space available only on the upper floor. Is it possible to have a lot of weight plates on an upper floor? Can they be stored on a rack? When does the point load with such a rack become too high?

We live in a Hjältevad house of 1.5 stories with raised wall height built in 2018, if that means anything in this context.

You should have received a binder with the house where this is stated. Living in a Smålandsvilla and they say that you cannot have a bathtub weighing more than 250kg without reinforcing the joists.
