Yeah, you definitely pay big bucks to live in Hawaii. My ex-girlfriend lived there along with her sister. We went back to visit for vacation for a few weeks, and it was quite expensive.
But considering I just spent two weeks in Europe, I can say that Hawaii is cheap compared to Europe and the dollar vs. the Euro! So at least you have something to be thankful for.
If you have some room in your condo, you could always pick up a few implements to use outside such as heavy sandbags, a dragging sled and maybe some adjustable dumbbells (Ironmaster.com) and maybe a mold to make your own strongman Atlas rocks.
