Dynamic Inertia is a fitness method or technology that’s been the subject of a lot of talk recently following the massive success of the Shake Weight.
On the official site of the Shake Weight you can read very little about Dynamic Inertia, only that it’s a:
New Workout Technology… which Increases Muscle Activity by More Than 300% Compared to Traditional Weights
This is claimed to be scientifically proven and supposed to get amazing upper body toning results in just 6 minutes of workout a day.
In the Shake Weight Review on this site, we’ve discussed how the opinions, testimonials, and reviews of the Shake Weight are mixed. Some fitness experts claim that it’s nothing more than a gimmick. Others say that they feel the burn that this device can give them very quickly.
It all hinges on Dynamic Inertia, this mysterious workout technology. I say mysterious because I couldn’t really find that many references to it before the ShakeWeight began to be promoted everywhere.
It may be a name which was actually attributed to how you workout with this product in the first plan.
The ShakeWeight, as the name implies, is used in a shaking motion. You hold the dumbbell like product in one or both hands and shake it vigorously to-and-fro as can be seen in the following video:
What is a Dynamic Inertia Exercise
As this seems to be a term which was first made public with the invention of the ShakeWeight, we can only surmise what it means. Basically, a Dynamic Inertia Exercise is done when you hold an object and shake it across a limited range of motion.
You need this object to have a certain degree of elasticity so it can vibrate in your hands. This actually forces your muscles to clench over and over again. This is probably the reason why Dynamic Inertia is supposed to boost muscle activity by 300%, according to the official website.
This means that you don’t have to exercise with the Shake Weight in order to achieve a dynamic inertia effect. You can find any object with elasticity and shake it.
One option that comes to mind is any of the workout bars that can bend. Holding them in both hands and shaking them in a variety of positions can have the same effect.
Does Dynamic Inertia Work
As this is a new term it is difficult to tell whether the claims made on the Shake Weight website hold real merit. There is no doubt that such an exercise routine does strain the muscles. However, due to the limited range of motion and the difficulty of using a variety of weights and resistance, it may not be as effective as traditional workouts.
The current recommendation of WorldofDiets.com is to not give up on traditional strength exercises because they are proven to work. Use Dynamic Inertia in addition to these workouts if you like, not in their place.
