Here’s What No One Tells You About Shake Weight Really Work

In today’s age, people are keen for quicker and more efficient ways to improve their physical fitness. Many products and programs can convince consumers so that they can form a good state in a short time.

Examples of these products include, but are not limited to, performing six Body blade exercises in a 6-minute routine, Abs Circle Pro 3-minute exercises, and Perfect Pushup. Some of these products have been experienced and verified, such as Body blade. Others continue to be subject to assumptions and analysis. Many times, advertising uses testimony rather than conducting proper research and verification in advance.

Similar to other products, Shake Weight (SW) claims, “it can increase muscle tone and create muscle clarity by reducing body fat” (Glenn 2012). SW’s strengths are based on the company’s reported concept of “dynamic inertia”.

Both ends of the modal are equipped with springs that allow heavy objects to move back and forth vigorously and claim to produce greater muscle size and strength growth than traditional training (Glenn 2012). The company pointed out that Shake Weight increased muscle activity by more than 300% compared to traditional weight, which is based on a comparison of isometric biceps curvature. (Glenn, 2012).

Isometric training and dynamic training through force generation and dynamic training through the power of the range of motion (ROM) were performed. Research shows that when comparing isometric contraction with dynamic training, isometric training increases isometric contraction. One of the concerns of isometric training is the lack of training for the entire ROM of each joint (Glenn 2012).

The study also examined specific angles of training response to isometric training. The results of these studies show that only within 20 degrees of the training angle, the force of contraction will increase. Isometric training seems to increase strength when training at a specific angle but does not increase strength through the full ROM of the joint.

If we compare Shake Weight’s electromyography (EMG) muscle activity to a traditional dumbbell (DB) performing the same exercise. Twelve men (22.9 years old) and thirteen women (23 years old) voluntarily participated in the study. The subjects performed chest shaking (CS), biceps shaking (BS), and triceps shaking (TS) using Shake Weight and DB, and all muscles showed the largest spontaneous isometric contraction (MVIC).

The EMG activities of the pectoralis major (PM), triceps (TB), biceps (BB), anterior deltoid (AD), trapezius (TR), and rectus abdominis (RA) were recorded, and Comparisons were made to detect the differences between the modalities. The EMG activity of each muscle group is reported as the percentage of individual subject’s maximum voluntary isometric contraction (MVIC).

Compared with Shake Weight mode, the muscle activity of DB in BB muscles during CS exercise was considerably improved. For any exercise, for any muscle group, Shake Weight has no improvement over DB. Besides, in any Shake Weight trial, no muscle group had an MVIC of more than 60%, which is a necessary level to increase muscle strength. The point of this study was to conclude whether traditional dumbbells repeat the Shake Weight mode of muscle activation when performing the same exercise.

The results of this study show that Shake Weight has no momentous increase in muscle activation compared to traditional dumbbells. A heavier weight can be used for this study to decide whether a heavier load will cause a higher level of activation when performing the same exercise.

From a practical point of view, when starting a similar style of an activity program, the traditional DB seems to be more economical. The data from this study also showed that the exercise to complete this procedure has little ability to produce more than 60% of the muscle activation of MVIC for almost every muscle tested.

Here I am going to some analysis as to their genuineness.

Regardless of the scientific proof claims, Shake Weight will not include information about the source or research that led to the proof in its literature. Due to the lack of clearness about the source of any scientific evidence requirements, it is difficult to determine exactly how companies make such requests.


There is no standardized definition of the term “dynamic inertia”. This seems to be a term pushed to the market by “shaking weight”. No research has shown that dynamic inertia can be used as a model for building and testing to improve adaptability.

The more muscle groups you participate in, the more calories you burn. Similarly, using a larger muscle group consumes more calories than using a smaller muscle group. Exercise intensity also affects the number of calories burned. The Shake Weight mainly uses the shoulders and triceps, but also some biceps and chest involvement.

You can increase the size and strength of muscles by performing activities that place micro-tears in the muscles. When they repair these tears with new tissue, the muscles become stronger.

Although it seems that the use of “magic” fitness products like Shake Weight can help you expand strength, it is important to systematically research the claims made by manufacturers of such products. In many cases, these manufacturers have made huge commitments based on lame research. If you have questions about products like Shake Weight, please consult a health or fitness expert.
