Damaging Floor Foundation While Exercising
Do you ever worry about doing high-impact (jumpy) aerobics on upper-level (2nd, 3rd, 4th, etc) floors?
Do you worry that it could damage the foundation and weaken the wooden floorboards?
My friend worries that continuously doing such exercises could destabilize and even break through the floor over time.
What do you think? Have you or anyone you know ever heard of such a thing?
