Weight for only six minutes a day is enough to get you lean and toned arms.

The Science

Dynamic Inertia: Dynamic Inertia works the muscles in the arms, shoulders and chest by constantly engaging the muscles which results in increased upper body muscle activity by more than 300% compared to traditional free weights.

The Study A “well-documented” scientific study involving the

Shake Weight technology was conducted by Dr. Daniel Cipriani. Professor at the department of Exercise Physiology at

San Diego State University Used EMG monitoring of muscle activity during use

of the Shake Weight™ compared to that of similar size dumbbells during traditional dumbbell exercises. All the major upper body muscles were measured. The

study revealed that the Shake Weight™ causes over 300% more EMG activity than traditional dumbbells of the same weight.

What We Found From Other Research

Shake Weight claims that they have a well documented scientific study but fail to provide it.

Shake Weight is compared with the use of a standard 2.5-pound free weight. A traditional weightlifting regimen for toning arms would gradually increase the weight well beyond 2.5 pounds.

It is hard to measure their claims of working out just 6 minutes a day.

Contradictory advertising: Claims to keep women leaner while making men bulkier.

Conclusion

Doesn’t really work better than regular training.

Dynamic inertia is still unclear to researchers.

Without the right diet, no results will be obtained.
