Sporty: Saran Wrap Anyone?

Saw the strangest thing at the gym last night.
Two women were saran-wrapping themselves in the locker room. They saran wrapped their mid-sections, arms and legs.

I had to ask. Their response - it makes you lose inches. Their theory is that you sweat more and the "tight wrap" forces your muscles to work harder. They first oil themselves then wrap their bodies. They told me that they even wear saran wrap under their clothes to work for maximum effect (but cautioned that I should wear a tank top as you tend sweat profusely).

Now I've seen several people working out in plastic outfits but the saran wrap was a new one. A quick search showed that people often use it for quick water weight loss.

Yeah, that was different.
