I'm not sure where the weights, apple and tape measure idea comes from, there are a whole bunch of them in this challenge... must be an American thing that us Brits don't get. This is the best of the bunch in my opinion though. Nicely focussed and exposed, and a nice combination of the primary colours.
A great adaptation of "an apple a day" meme. Clear, crisp communicating how one accomplishes standard fitness. Great composition and execution of the central idea. Well done.
