Graphics: Linoleum cut, a little quick design just for the fun of it:
This is a pun on the Danish term "bæredygtig". The term is the Danish word for "sustainable" in the Brundtland-sense.
The verbatim meaning of the Danish word is something along the lines of "Skillful in carrying". Further, in Danish a weight lifter is also a person who carries a weight (after it's lifted it is carried until it is dropped)
This type of pun may not be foreigner-friendly, but then I hope you may at least enjoy the print.
Update: After taking the photo above the Gs have been changed slightly so that they now look less like Cs.
