Apple Makes amazing products that i have always loved. However, I feel that it has always been easy to make fun of thier advertising and marketing ideas.  I would change the prices, some videos and give the site a darker, evil corporation look.

We are all familiar with the corney "as seen on tv" products that appear on infomercials at 3am.  These products are usually useless gadgets that are insanely overpriced.

this site looks like a joke to begin with.  As another ass seen on tv product, this one is just to easy to make fun of.  Fitness is done with hard work, not with gimmick products.  I would make this site even more ridiculous with crazy testimonies and exaggerated results.
