Home fitness DVDs seem like a good way to reach exercise goals, but experts say these DVDs may also include negative imagery and demotivating language. The fitness DVD industry generates an estimated $250 million dollars in annual revenue, but there is no scientific evidence about their safety or effectiveness and the industry is largely unregulated. Investigators evaluated ten popular commercial exercise DVDs and found the imagery in the fitness videos perpetuates and reinforces hyper-sexualized and unrealistic body images. They also found that 25% of the language used by instructors was motivational, but one of every seven motivational statements could be considered negative. Dr. Brad Cardinal, a kinesiology professor at Oregon State University explains, “These findings raise concerns about the value of exercise DVDs in helping people develop and commit to a workout program… Buyers should beware when making these purchases… Remember that we all have different body shapes and styles, and our bodies may respond differently to the exercises being shown. Don’t expect to get the same results as what you see on the screen or compare yourself to others.”
