Our Story
Leon Anderson opened his first gym in 1987 at age 20. By 2007, he was helping others do the same—without overpaying or giving away control.
In 2010, he launched Mammoth Gym Supply to combine wholesale fitness equipment with real-world startup guidance.
Today, Mammoth serves hundreds of gym owners nationwide with commercial-grade gear and proven systems for launching or growing a fitness business.
