Mark Eden bust developer

Mark Eden bust developer was a device and accompanying program marketed in the 1960s and 1970s as a way to increase a woman's bust size through isometric exercise. Despite its popularity and widespread advertising, the product was eventually discredited due to false advertising and lack of scientific evidence supporting its claims.

Overview[edit | edit source]

The Mark Eden bust developer was a product that claimed to help women enlarge their breasts by using a special device designed to apply tension to the pectoral muscles. The theory behind the product was that by strengthening and enlarging these muscles, the bust size would naturally increase. The device itself was a simple hand-held contraption that users would squeeze together using their hands and arms.

Controversy and Legal Action[edit | edit source]

The effectiveness of the Mark Eden bust developer was widely disputed, leading to legal action. In 1971, the United States Postal Service charged the company behind Mark Eden with mailing obscene materials and making false representations in their advertisements. The Federal Trade Commission (FTC) also took action against the company for false advertising, leading to a cease and desist order. The company was required to stop making unsubstantiated claims about the product's effectiveness in increasing bust size.

Scientific Evaluation[edit | edit source]

Scientifically, there is no evidence to support the claim that isometric exercises targeting the pectoral muscles can significantly increase breast size. Breast size is primarily determined by genetics and body fat percentage, not muscle strength or size. The Mark Eden bust developer's premise relies on a misunderstanding of human anatomy and physiology, as the breasts do not contain muscle tissue that can be enlarged through exercise in the same way that biceps or other muscles can.

Legacy[edit | edit source]

The Mark Eden bust developer is often cited as an example of false advertising and the exploitation of women's body image concerns for profit. It serves as a cautionary tale about the importance of skepticism and the need for evidence-based claims in advertising, especially regarding health and beauty products.
