Shake Weight: The Viral Fitness Product That Shook Up Infomercials

What Is the Shake Weight?

The Shake Weight is a handheld dumbbell with a spring-loaded mechanism that oscillates when shaken. Marketed as a way to tone and sculpt arms, chest, and shoulders in just six minutes a day, the Shake Weight was targeted primarily at women (and later men) seeking a quick, low-effort fitness solution.

Unlike traditional weights, the Shake Weight uses something called “dynamic inertia,” which forces the muscles to contract rapidly due to continuous shaking motion. Whether or not the science fully holds up, the product certainly made a splash.

How the Shake Weight Became an Infomercial Sensation

Launched in 2009 by Fitness IQ, the Shake Weight wasn’t just another late-night fitness gimmick. It quickly became one of the most viral and parodied infomercial products of all time — for better or worse.

The Infomercial That Broke the Internet

The original infomercial featured women intensely shaking the product with suggestive motion, unintentionally giving it a risqué, almost comedic quality. It went viral almost immediately, gaining millions of views online and becoming fodder for comedians, late-night hosts, and viral video creators.

Saturday Night Live, The Daily Show, and South Park all satirized it — helping boost brand awareness rather than hurt it.

Marketing Genius or Just Lucky?

While critics called it “ridiculous” and “the most awkward fitness product ever,” the controversy fueled curiosity — and sales skyrocketed. The product’s infomercial managed to blend humor, visual intrigue, and outrageous claims into a formula that audiences couldn’t ignore.

Results and Claims

The Shake Weight claimed it could help users tone arms and upper body in just six minutes a day. Some users did report feeling a burn after use — but fitness experts were divided on whether it offered real long-term benefits.

Sales and Legacy

By 2010, the Shake Weight had sold over 2 million units and became a pop culture staple. A version for men was later released, with a heavier weight and a more intense infomercial.

The product’s legacy lies not in its effectiveness, but in its status as a case study in viral DRTV marketing. It proved that even seemingly absurd products could generate massive revenue with the right blend of media exposure and curiosity.

Where to Buy the Shake Weight Today

While its peak has passed, the Shake Weight is still available online through major retailers like Amazon and eBay. It remains a fun novelty item — and yes, some people still use it for real workouts.

Final Thoughts

The Shake Weight wasn’t just a fitness tool — it was a cultural moment. It shook up the fitness industry (and the internet) with an unforgettable infomercial that turned laughter into profit. Whether you saw it as genius or gimmick, there’s no denying its place in infomercial history.
