Well, I can't wait to see how this turns out. A pilates ring is not per se a stupid idea, and I like the brace thingy with the Joycon strapped to it.
Nintendo just can't help themselves. Being quirky is part of their DNA.

Somebody already posted it, but it's a Pilates ring, and I absolutely hate it. 

The poor folks at Nintendo probably don't know any better, since Japan is not big on gyms, but "exercise" like this and Wii Fit misinform and mislead. 

The goal of exercise is to lose fat and build muscle. BBB Routines (Bosu Balls, Bands, and Baby/Body Weights) are bad at both. Fat loss is done in the kitchen, not the gym. You can't out exercise a bad diet. The point of exercising, on a diet, is to preserve any muscle that you have, while you are on a calorie deficit (Your body wants to lose muscle when you are not getting enough food.) The more muscle you have the higher your metabolism is. Having more muscle prevents yo-yo dieting, where you just gain back all the weight you lost when you come off your diet. In order to build or keep muscle you need to lift heavy enough that you can only do four to ten reps per set. BBB Routines are the exact opposite of that. They are also very popular with women, because many women are afraid of getting bulky (they can't because they lack the testosterone required). 

"But Cerebral, I know this one fitness guru who does bodyweight exercises and is in great shape!"

Yeah, that's because...

1. He got in that shape by lifting heavy weights on a real training program, and is now just maintaining. 

2. And/Or he is on steroids. 

3. He is genetically gifted, and predisposed to putting on muscle easily. 

Now, don't get me wrong here. There are good bodyweight exercises that can be fit into a proper routine. Dips, and Pullups for example work well. But that is because with both of these exercises you are moving your entire body vertically. When you do pullups you are lifting 100% of your bodyweight. When you do dips you are lifting 100% of your bodyweight. The same cannot be said for pushups, situps, crunches, planks, or barless squats. 

@Cerebralbore...

Or maybe some people like to exercise because they like the way it makes them feel. There doesn’t always have to be an end game in it. I can tell you are knowledgeable about those things, but maybe you’re overlooking joy as a motive.

I get that. The problem is that these sort of things are rarely just marketed as fun. They are marketed as good exercise. Want to charge people money to play fetch with your dog for fun? No problem. Want to charge people money to play fetch with your dog and claim it will make them lose 20 lbs in a month? Now we have a problem. 

That's not Nintendo's marketing.  They are interested in people being active...but being active doesn't equate to weight loss.  Nintendo always handles their marketing in this respect safely and without promise.  Nowhere in that commercial did I see anyone look at their weight on a scale at one point, and then show excitement at looking at it again in another shot.  That would be marketing 101 for a weight loss program.  WiiFit focused more on wellness, balance, and breathing than anything else.

I know there are devices out there and companies who push certain miracle ideas with the sentiment you have expressed, but that isn't happening with Nintendo.  Their focus is simply on fun and finding new ways to get people to have fun.  I think this is aimed more at people already on a Pilates routine who will now have a way of gamifying their existing routine.  Tht sounds like a beautiful thing to me. Gamification is always a great way to keep people motivated and energized.

"You will lose weight, or build muscle" is implied in the name Wii Fit. 

Nintendo won't market it in the way you described above. They are better than that. I agree. 

But that isn't going to stop soccer moms, and the general media from being like...

Haha!  You're right about that.  But then those demographics will say that about anything.  Particularly those things that don't actually involve true exercise or changing your diet.  Those are always the things they focus on.  It's the "man bites dog" part of media.  Certainl it would be boring news to just simply tell you the facts, but if we can provide this wacky crazy method that probably dosn't work...but might...then we've got your attention.  

I understand your reflexive eye roll.  I just wanted to make sure we were on the same page about where to apply blame.  Also, regarding the WiiFit name, would you have rather they called it the WiiBalance, or WiiScale, or the WiiBoard?  At some point in time you do have to let the marketing team come up with something somewhat catchy and inviting.  Also, the WiiFit specifically had a section in every day's routine for you to fill in your separate (and vital) workout routine.  WiiFit was just a great relaxation tool that you could use to keep track of your progress.  It was a beautiful machine and my only problem with it was that they forgot to actually put a game inside as well.  Once you finished your goal it didn't do crap.  It just said, "make another goal."  It really missed a great opportunity there.

Wait there's no exercise program built into Wii Fit? I guess I've never actually used one. So it was just a scale/balance board, with a place to write down the real workout routine you did on the side? Lol now I have to watch some youtube videos of people actually using the thing. 

There were certainly exercises.  Mostly yoga routines, pushups, crunches, low impact stuff.  I mean, what really could you do with that hard piece of plastic anyway?  But the music was pretty cool and relaxing.  I definitely got more of a workout on a good session of Wii Tennis.

Agreed, to this day Wii is my second top console of all time and a big part of that is amazing games like Galaxy 1/2, Prime 3, Xenoblade, etc.

Also agree, Wiimote Plus & Nunchuk is in my opinion still the best video game controller ever made.
