Adjustable dumbbells in Belgium?

Hello to everyone!

Any Belgians around here? I currently live in Antwerp, Belgium (though not originally from here) and I've been wondering about stores that may sell adjustable dumbbells, for example the powerblock set.

Alternatively, did any Europeans have experience with ordering from the US? I'm a little worried about custom fees and other unexpected charges.

I really want to step up my game during the summer, so any advice will be much appreciated! Thank you, and have a great day :)
