All about ABS! (Infographic)

A fun fact about abs: the first six-pack shown across the silver screen caused quite the stir! When Gone With the WInd actor, Clark Gable removed his button-down and bared his belly in the 1934 film, It Happened One Night, it’s said that undershirt sales plummeted! Well-defined abnominal generally become visible at around 10 percent body fat or lower, but nearly 90 percent of U.S. adults are unhappy with their abdominal muscle tone, and would gladly have a flatter stomach or lose that stomach fat altogether.
