this actually is possible and has been tested. the large hadron collider speeds partials near the speed of light, when this happens they gain mass becouse they gain mass they gain wight. so if there are engineers here, you got it work with lack of imagination. if you speed up an object near light speed it gains mass. for a dumbbell it would only something inside it would need to be accelerated just a fraction of the seed of light to give a few pound increase. everything seems impossible before it is done.

I think it may be worth pointing out that a subset of excercises for which dumbells are used would involve rotation of the dumbell about an axis that is not aligned with the dumbell axis. An example of such an excercise would be lifting of the dumbell from arm relaxed (axis horizontal) through 90 deg arm bend (axis vertical) to bicep fully contracted (axis horizontal). This motion would generate a resistive couple, increasing the work required (although the majority of the additional muscular requirement may be unlikely to come from the biceps/triceps.

I am also an engineer and do agree with above comments insofar as the product is unlikely to function as the designer intended and that it would be helpful if the designer had a more thorough grounding in engineering/mechanics in order to avoid wasted effort. I do, however, disagree with the way this was highlighted in this thread. As engineers we should both understand that product designers may posess talents that are outside of our own expertise and that an agressive approach is unlikely to convince a designer to improve their understanding of engineering principles

I’M AN ENGINEER AND I CAN TELL YOU THAT THIS IS TOTALLY IMPOSSIBLE!!!

Ironically I did ask many people about this concept, and they (all non-engineers, just product designers) said it made sense!

What you would get with this is similar to a POWERBALL. Like a Powerball, it won’t increase in weight but create a rotational force.

This design is cool, but impossible. You guys have to remember that product designers may be artistic, but have no real intelligence.

even if it does increase the mass (which i don’t see how that can happen), it isn’t practical.. this is just a simple design which is only useful for a very limited work out..

the design does look cool, but that is all there is to it…

I studied industrial design, and I also studied engineering. Why do designers think they can whip any product into a “design” by making it 1) digital, and 2) unnecessarily complicated? (in this case, by invoking non-existent or wrong science?) That is not the point of design. Any fool can say “poof! It’s digital!”. Any infomercial will show you how to make something unnecessarily complicated.

I’m shocked this designer’s instructors didn’t call him out on this. Shame on them.

Emphasize the “Dumb” in dumbbells in this case.

Wrong concept; the powerball resists being turned; it does not resist being lifted. Gyroscopic reisistance only resists changing directions, but it does not make the thing any heavier.

If this pair of dumb-bells is intended to build your forearm’s twisting strength, it might work, but you can’t really expect it to build your biceps or do any conventional exercises with it.
