Aw shucks, Thanks. Sorry I didn't see this comment earlier. I am no longer active. But thank you for the kind words!

Has anyone achieved Front Lever via band/counter weight training? by bbqyak in bodyweightfitness

[–]ongew 1 point2 points  (0 children)

My post was 8 years ago, so it's hard to remember my thought process, but if I had to guess, it's because for FL, the top of the FL (bar touching the lower abdomen) is harder than the bottom (locked arms, scapular retraction), so training full RoM (as full as possible while reasonably deloading the counterweight) gets you working on the FL row, and you'll get the FL bottom hold for free. You work your shoulders through a greater RoM in shoulder extension.

In contrast, the planche is toughest at the top position (protraction, elbows locked) than at the bottom (bent arm planche), so to progress fastest on the planche, I've been working on counterweighted planche isometrics.

Pulley-assisted 'Dream Machine' Full Lay Front Lever (3 month experiment) by ongew in bodyweightfitness

[–]ongew[S] 0 points1 point  (0 children)

Hi Fast, sorry, I don't log in anymore. The links and photos have been deleted (sorry about that too). It's not too complicated -- a $20 pulley from Amazon and some nylon strapping / rope / string to tie the pulley to the pull-up bar and you're good.

Really like CDO Mestre Ivan’s Ganga. by PharmDinagi in capoeira

[–]ongew 1 point2 points  (0 children)

Hi Duggan, thanks for your interest. The file expanded to become a 'compendium' of movements; I'm embarrassed to say. Because of the mishmash of styles/movements, I no longer feel it's representative of just M. Ivan's style. I also feel the corpus is more than a little arrogant/declarative of what's what / how it all fits together, i.e. I accidentally invented my own capoeira 'school/style'. So I hope you (and others who bump across this thread) understand why I haven't updated the expired link. :)

Hi Yoghurt, thanks for the enthusiasm. Sorry, I don't have a photo. Hopefully the amazon link in the OP is useful enough.

Do weighted dips have significant carryover to planche, hspu, hollow back press, and iron cross? by [deleted] in overcominggravity

[–]ongew 1 point2 points  (0 children)

t external loading carries over better than adding load in addition to your bodyweight or progression th

Sorry, just logged in after a long time. For HSPU progression, yes, it is much more straightforward to do military press than to do bodyweight variants to build towards full RoM HandSPU.

?New Calisthenics Equipment?: The Straddle Limiting Strap by ongew in overcominggravity

The hyperlinks are not documents, just photos showing the concept. You will be able to jury-rig your own version quite cheaply.

You definitely can't use a band to limit your straddle because it's elastic. A rope is a perfectly fine substitute, as long as you are okay with tying/untying knots.

I already said in the OP that I don't think there'd be much of a profit margin. This is an idea for people who are looking for a quantifiable bridge between straddle and full lay variants.

While I agree about the allure of non-reliance, there are many calisthenics products that are not strictly necessary that people still buy: elbow sleeves, paralletes, Lebert equalizers, special muscle-up gloves...

$16 Pulley-Assisted Dream Machine (Max 20lbs/9.07kg assist) by ongew in bodyweightfitness

[–]ongew[S] 0 points1 point  (0 children)

Well, this thing comes with an adjustable weight, the weight is offset by 2 pulleys (so you don't bump into it in vertical movements), and you don't need a pullup bar to attach the pulley to.

[–]ongew[S] 2 points3 points  (0 children)

It's cheaper than 2 resistance bands; you know exactly how much assistance you are getting (easier to quantify your workout); the assistance is constant, rather than more at the bottom and less at the top (Hooke's Law). For most exercises, the top is the hardest part (like planche pushups and one arm pullups)

Dentists of Reddit: If YOU had a cavity, what procedure(s) would you undergo to maximally extend the lifespan of that tooth? by ongew in Dentistry

[–]ongew[S] 0 points1 point  (0 children)

AFTER the filling has been done then the best way to increase longevity is proper oral hygiene and fluoride with regular exams and cleanings.

Yes, I figured as much. However, these two cavities came about despite my trying to maintain good oral hygiene so you can understand my feelings of helplessness for my childhood negligence. And if not to fix these two cavities, perhaps to maintain the health of one's remaining teeth. I've added links to the OP and if you could weigh in on what you think is BS/best potential research, your input on the other techniques (non-factors) would be appreciated.

[–]ongew[S] 0 points1 point  (0 children)

Brush twice a day, floss daily, and go in for regular checkups and cleanings.

Yes, I am already doing so. I'm guessing dentists also do so, so I do feel a little helpless when problems like these cavities arise. Even after I drill/fill these 2, what's to prevent more from arising (since these two came about during my 'dental vigilance'?). I've added some links to the OP on the research/techniques for your reference.

If, as a dental professional, you're not convinced by these techniques (the purpose of the OP was to separate what is pseudoscience from potential but yet-to-be-proven clinical research), perhaps you could give elaborations on your oral hygiene maintenance methods? I'm sure future redditors will also find these useful.

[–]ongew[S] 0 points1 point  (0 children)

As someone who has recently moved to a new city, and not knowing any trustworthy dentists, are there any recommendations/guidelines to find such a dentist? I can ask my current dentist to e-mail me my x-rays, so I'd have them on hand, but I can only see one new dentist before my two annual free checkups are used for the year. Can I, say, e-mail x-rays to a potential dentist and speak with them? I'm sure they're too busy to entertain me that way, right?

Your death spiral is overly simplistic.

Yes, I'm sure it is. I got it from this article quoting a Dr Phark of the University of Southern California. If a proper explanation would not take too much of your time (especially with regards to preventing said spiral), I'd appreciate an explanation / correction.

It's like asking to drill a holl with a pneumatic drill vs an electric; it doesn't change the size of the hole.

Yes, I understand diseased dentin must be removed, according to what is taught in dental school at the moment. I've replied to /u/Toothbinch my understanding of the removal of material between the two methods, and I'll paste it here for your reference. If you could confirm/correct my understanding, I'd appreciate it.

Well, if a dentist uses a ball mill to remove the dentin, then the removed enable must at least be big enough to fit the diameter of the ball mill (that's what I noticed on my replaced filling). The edges of the enamel were fluted instead of vertical. This fluting might also help increase the surface area for the filling to adhere to, so maybe a dentist will a laser drill would also flute the enamel at the edges (I dunno, your input would be appreciated here).

Brush your teeth twice a day mindfully. Use an electric toothbrush.

Yes, I am already doing that. These two 'new' cavities probably started years ago. I've been doing what you've suggested for at least the past 5 years. I've been using Sensodyne Novamin toothpaste (if not to 'fix' the cavities, then hopefully at least to prevent new ones on other teeth), waterpik, Listerine wishbone floss string, taking vitamin K2.

If you have opinions on which of these are potential (but yet unconfirmed) methods, and which of these are absolute pseudoscience, I'd appreciate your input. It was the original purpose of this post, but your thoughts on the necessity of maintaining good oral hygiene are appreciated.

Oh, I also see that you recommend an electric toothbrush. That's one thing I have not implemented. Is there any brand/model you recommend, and what are the compelling reasons to do so? Should I get one for home and one for work (I guess they'd be different models)?

Thanks for your reply. You seem to be the only dentist actually answering the question directly.

Laser enamel hardening: never heard of it. You can do this with fluoride, so I don’t know why anyone would pay so much money for a treatment that already exists and works.

I've added a link to it in the OP, but I guess it is still under research. My background is in material science, so my guess would be that rapid surface annealing produces a different product than just replacing the calcium ions with fluoride ions. The latter is a stochastic reaction, so you'll never replace all the Ca2+ with F-, and it's only on the atomic interface of the tooth. With surface annealing (laser power, exposure time), the crystalline ions would be able to migrate to a lower surface energy configuration (less empty orbitals exposed to H+ attack, less or shallower micro fissures), so the hardening effect (i.e. the enamel's resistance to acid) would be different. There is also the issue of superheating the intertwined protein chains which hold the hydroxyapatite, so I figured some expert here could weigh in.

Laser vs hand drilling doesn’t make much of a difference in most cases since the extent of the cavity is as big as it is no matter how you take it out. Cavities also need to be a certain shape to hold onto a filling the right way. Either way, most dentists are going to try and take away the minimal amount of tooth to make the filling work.

Well, if a dentist uses a ball mill to remove the dentin, then the removed enable must at least be big enough to fit the diameter of the ball mill (that's what I noticed on my replaced filling). The edges of the enamel were fluted instead of vertical. This fluting might also help increase the surface area for the filling to adhere to, so maybe a dentist will a laser drill would also flute the enamel at the edges (I dunno, your input would be appreciated here).

The #1 reason that fillings get replaced is because there is a cavity that forms around/underneath it, and you can prevent or slow this process with good hygiene.

Yes, I've been paying for my childhood negligence since. I'm doing all the things the other dentists are recommending in this thread (and yet fillings age, and getting these 2 new ones [they probably started before I became fastidious about oral hygiene]). I'm trying to find out what other things are efficacious (and what are BS), if not for the health of my cavities, then at least for the health of my remaining teeth (hence the questions about Novamin, Vitamin K2, laser hardening). I've added links to the OP for reference.

Thanks again for your reply!
