The manufacturer of the Hawaii Chair claims it is an “easy-to-use waistline slimming and fat burning aerobic workout exercise machine”.

Instead of spending $300 on this product, go for a walk or a run.

If you do want a good core workout, watch this video of Ellen DeGeneres demonstrating the chair on her talk show. I am sure I received a better ab workout from laughing at this video than I would have if I were to buy this chair.
