About Shake Weight Duo

Published on: Jan 7, 2015

Manufactured by Allstar Products Group, the Shake Weight Duo is claimed to be a revolutionary new way of helping women get an incredible workout and shape and tone their arms, abs, and upper body in just 8½ minutes per day.

In order to provide maximum results in the shortest amount of time, Shake Weight Duo is claimed to use “dynamic inertia,” which the manufacturer states can increase your muscle activity 300% more than traditional weights. And by combining this inertia with rolling, twisting, pushing, and pulling motions, Shake Weight Duo is claimed to be a shortcut that can provide you with amazing results.

You may have originally scoffed at the first version of the Shake Weight, but now that the Shake Weight Duo has been released, you’re wondering if it really works as advertised. So does it? Probably not, and here’s why:

What’s Different About the Shake Weight Duo?

When compared to the original Shake Weight, whose weights were fixed, the weights on each end of the Duo appear to act like wheels, providing them ability to roll on the floor, and you the ability to push, pull, twist, and turn your body for increased resistance training. However, the central idea behind both the original and updated versions is the use of something called “dynamic inertia,” which we’ll talk about more next.

What is Shake Weight Duo’s “Dynamic Inertia?” Can it Really Help Improve Your Fitness?

Both the original Shake Weight and the new Shake Weight Duo appear to feature springs inside the handle that are attached to weights on each end, which shake when moved. Once this occurs, the inertia created by the movement of the weights is claimed to work different muscle groups in your arm, depending on how it’s held.

However, just because you’re increasing muscle activity (even by the 300% claimed by the Duo’s manufacturer), this doesn’t mean that the motion can provide you with any fitness benefits. This is because effective muscle growth and toning involve targeting specific muscles groups. And, as WedMD noted, “For a muscle to be fully stimulated, resistance must be applied through a full range of motion. The Shake Weight does not deliver this and will not result in the same muscular activity as traditional dumbbell exercise, despite what the company claims. Also, you cannot add additional weight to the device and it offers limited exercises. A muscle improves when it is continually challenged with increased resistance and targeted with a variety of exercises. Therefore, very little (if any) results should be expected with the Shake Weight.”

For a more complete picture of some of the problems related to the Shake Weight (and by proxy, the Shake Weight Duo as well), we’d recommend typing “how does the Shake Weight work” into your favorite search engine, which will return dozens of results.

You’ll Need a Balance of Exercise & Diet to Achieve Lasting Results

Finally, even if exercising with the Shake Weight Duo did help tighten your muscles, toning them is often more about diet than it is about exercise. In other words, regardless of how chiseled your arms or abs may be, if they’re covered in a layer of fat due to poor diet choices, all of your hard work may not be visible to show off to others. 

Regardless of how hard you workout though, you almost certainly won’t receive enough resistance training to make much of a difference in the 8½ minutes advertised by Shake Weight Duo’s manufacturer.

Are Consumers Getting Results with the Shake Weight Duo?

Shake Weight Duo had recently been released at the time of our research, and didn’t have any online consumer reviews available.

However, the Shake Weight Duo is manufactured by Allstar Products Group, a major player in the ASOTV industry who also makes popular products such as Chop Magic, Perfect Bacon Bowl, and Spicy Shelf. Based on more than 130 HighYa reader reviews for these products, they have an average rating of 2 stars, with some of the most common complaints citing:

  • Poor quality products that don’t work as advertised,
  • Orders processed without approval from customers,
  • Excessive S&H costs (more about this next), and 
  • Poor customer service (unknowledgeable staff, difficulty processing refunds, numerous upsells during calls, etc.).

Granted, this isn’t necessarily what you’ll experience with your Shake Weight Duo, although it’s something to keep in mind when placing your order.

With this said, as a company Allstar Products holds an A+ rating with the Better Business Bureau despite having nearly 250 closed complaints (as of 1/5/14), many of which reference the same problems noted above. 

Shake Weight Duo Pricing & Refund Policy

The Shake Weight Duo is priced at $19.95 plus $7.95 S&H, which also includes an inflatable knee pad and “Flab to Fab” DVD.

The Shake Weight Duo comes with a 30-day refund policy, less S&H charges. This means that if you’re dissatisfied and decide to return it, you’ll likely spend more than half as much in S&H charges as you’ll ultimately receive as a refund.

With this in mind, if you’d like to request a refund, you’ll need to contact customer service at 855-663-5645.

Will Shake Weight Duo Get You in Incredible Shape?

Chopping to the Point: Considering that the original Shake Weight has not been found to be effective from numerous authority websites and physicians (and the Shake Weight Duo appears to work using the same principle), we’d recommend speaking with your physician about more effective methods of toning your arms, abs, and upper body.

However, if you do decide to roll the dice on the Shake Weight Duo, keep in mind that you’ll spend about ½ as much in S&H charges as you’ll receive as a refund if you’re not satisfied.
