Whiplash Exercise
People from every era were after envy-inducing ab muscles. One way to achieve this look was with this popular core belt. The 1930s gave birth to several dangerous ways to drop pounds or gain muscles. This machine in particular was pulled from shelves after users suffered whiplash from a workout.
