Hi Twisty Puzzles fans,

Workout Cube is a regular 3x3x3 Rubik's Cubes that has friction plates. These friction plates dampen the rotation of the centers, using a viscous fluid, like Vaseline.

The idea for this puzzle came up in a discussion between Ulrich Meffert (the son of ...) and me. Currently, speed-cubing is incomprehensible to watch, as it goes too fast to understand the solution approach used. A commentator could not keep up with the solver to provide commentary. One solution would be to provide commentary on a solving video in slow motion. Another solution would be to slow the solver down. As each turn takes a lot of force and time, the Workout Cube would force the solver to rethink solving algorithms, as now minimal-number-of-moves solution become more important than fast-to-finger-trick moves.

The puzzle was designed and made by me, with parts 3D-printed by Shapeways.

Watch the YouTube video.
Buy the puzzle at my Shapeways Shop.

Enjoy!

This is the silliest idea ever, but I love it!

My normal Rubik's brand 3x3x3 turns just like this, I could swear it has the same mechanism.

Ha! Great idea, good for those of us who play racquet sports like squash and badminton. For a stiffer mechanism, what about using a system where the vaseline is forced through a small opening(s). Changing the size of the aperture(s) would change the force needed to turn it.

Usually we always hope to design some speed cubing puzzle. I never thought there'll be a puzzle uniquely designed as to lower the speed!

I like this idea!

Interesting mechanism. The viscosity of the Vaseline I think would be highly temperature dependent. So speed records would now need to include the temperature of the cube. I'd also be concerned about how well the cube contains the Vaseline. If you leave this sitting in a window sill on a hot day do you end up with a big mess as the Vaseline seeps out of the cube?

As for the question at the end of the video, I imagine there is a group that would say you could stick some magnets inside the cube. Actually hasn't that already been done? Not that I think it would really be any healthier but that seems to be the fad these days.

Actually... couldn't you use a very similar mechanism except make the fins on each axis out of very powerful neodymium magnets. The core structure could be made out of copper. Provided you could actually assemble the cube without crushing your fingers between the magnets, I think you could make a nice heavy cube which also had a lot of resistance to the faces turning. And once turning you would even have to use force to get them to stop turning. An example of the effects I'm talking about can be seen here:

Such an object though would actually be rather hazardous to your health. You'd certainly not want to drop it on your foot or get it too close to any iron objects. That said... I think it would be incredibility cool to own such an object.

I now have this image in my head of a "speed" solver (or should we now call them strength solvers) making the last solving turn on such a cube and dropping it on a heavy wooden table to stop the clock. Only he's failed to break that last turn and the last face continues to rotate slowly for several turns while sitting on the table by itself.

So the future world record holder in this puzzle will have huge, muscular forearms and no one will dare call him or her a nerd! In all seriousness, the idea of adding a bit more physical activity and effort to our rather sedentary hobby is a good idea.

It reminds me of the Knucklehead mechanism.

It's really a good idea . Especially for speed cuber.

You know, this could be a good warmup tool for speedcubing, like how basebally players put those weighted donuts on the bat during warmup swings. It would also make for a rather hilarious WCA event in and of itself. It'd probably turn into some interesting combination of a fewest moves vs speedsolving event.

The magnets idea from wwwmwww is pretty good; it'd also add a bit of weight to the puzzle, which would be fitting to its name.

Actually, you should just combine two workout cubes into a Dumbbell Cube version 2. THAT would be one heck of a workout. If you made the gearing mechanism sturdy enough, you could increase amount of required force to turn a single face (instead of turning one face, you're now turning two) and simultaneously add the challenge of solving a dumbbell cube (which requires extra moves).

In my opinion it took you quite a lot of complexity to make a cube that I had in 2005 when I bought a Rubik's brand 3x3x3.

Also this will only stress tissues. The muscle training effect will be small even in the fingers.

No, this time you couldn't convince me, sorry.

Speaking of insane ideas I want to see a Rubik's cube where each cubbie has a magnet and with with no stickers but the solved state forms a Halbach array. To solve you have to test the magnetic field

I wouldn't use Osmium:
Wikipedia wrote:
Osmium tetroxide is highly volatile and penetrates skin readily, and is very toxic by inhalation, ingestion, and skin contact. Airborne low concentrations of osmium tetroxide vapor can cause lung congestion and skin or eye damage, and should therefore be used in a fume hood
Obviously you should use Iridium, as it is 99.87% the density of Osmium but does not kill you if you touch it

Gives a whole new meaning to the term "killer solve" though
