I'll answer as a two part response. Let me first say people have free will and do not have to prescribe to a strength programme. Although people are entitled to this choice it is self limiting. Strength training causes hormonal responses in the body which encourages toning and fat loss - you MUST lift heavy to move fat - only the style or methodology varies between lifting for a figure/bikini model and a body builder.
That said there are other health benefits including increased muscle, tendon and ligament healthy, improved posture, improved flexibility and joint health, increased bone density and health, LOWERED risk of heart disease and many other benefits.
A complete health approach includes a strength aspect. It is about the internal benefits, looking better visually is simply a bonus.
