The Shake Weight is an As Seen on TV product marketed to individuals looking to strengthen and tone their arms. The product manufacturers claim that in as little as six minutes per day, you can have a toned upper body. Although you may reap some nominal benefits from the Shake Weight, the product will not remove arm fat.

The concept behind the Shake Weight is that it uses Dynamic Inertia technology to work the muscles in the upper body. Dynamic Inertia refers to the oscillating movement of the weight when in use. This extra movement is intended to cause a higher force output during exercise. According to the manufacturer, you’ll increase muscle activity by 300 percent more than when you use traditional weights.
To use the Shake Weight, you are instructed to first spend several minutes shaking the 2 ½ lb. dumbbell up and down. The instructional DVD walks you through several different arm exercises such as bicep curls, arm raises and tricep extensions. The workout is over in six minutes because each exercise is done for only one set.
According to the American Council on Exercise, the Shake Weight does not provide the necessary stimulus to train the muscles in the arms. Since the weight is only 2 ½ pounds, you will not see increases in muscle tone and strength. The Shake Weight can also be awkward to use correctly in order to work the muscles in the arms.
It is not possible to spot-burn fat in any area of the body, including the arms. If you want to lose weight, you’ll need to follow a calorie-controlled diet and regular sessions of cardio exercise. Strength training exercises, such as bicep curls, tricep extensions and pushups, can build muscle in the arms to decrease the appearance of fat in the arms. You should strength train at least three days per week.
