The post is good! I like the post! Thank you for posting :3

I just like to shill for resistance training, it transforms people’s lives. Posts like these are a great opportunity for me to do so, where it’s mentioned offhandedly and maybe with a misconception I can talk about

I’ve had several people on fedi reach out to say these comments have helped them out in some way, so it’s just something I like to keep up with :3

Yeah :3 Just based on teaching people to do various chest exercises, wrist pain is usually caused by holding the implement too far up the hand, creating a moment arm that bends your wrist open. Around 150-200lbs is usually when people stop being able to tolerate such a grip

If you search this page for “bench grip” it will take you to an image of three hands, the rightmost of which has a red line and a green line. Best image I’ve ever found for communicating the spot. If you get it down you should feel no discomfort at all in your wrists

Haiiii hii hii just want to pop in with a couple fun facts,

There’s no serious risk of damaging your joints from lifting, actually it’s the opposite. Resistance training will reduce the likelihood of injury throughout all stages of life.

There also isn’t really any hint of truth to the old myth “muscle growth is the result of damaging the muscles so they grow back bigger”. It stems from very early misinterpretations of experimental data and became something people just repeat forever with no factual basis.

Catabolism (breakdown of muscle) occurs all the time, and is usually balanced by anabolism (building muscle). It would be more accurate to say that “sufficiently challenging bouts of resistance training stimulate greater rates of anabolism for a period of time which result in a net gain of muscle mass”

Many common factors can tip the scale towards catabolism which is very bad for your health and quality of life (sarcopenia, menopause, HRT in some cases) and training is the best most consistent lever we can pull to mitigate those negatives. Women especially reap massive benefits from training, doubly so after midlife

I almost never encounter it anymore because I habitually just open a new tab for everything. A habit I started doing because encountering it made me so angry I almost swore off computers altogether

Super niche adjacent rage but shoutout to max-for-live developers who implement their Ableton plugins as a series of user actions so that the instant you touch the plugin it detonates your entire undo history

Thank you! It is a privilege and a joy to have made such a remarkable improvement to your life!

Sadly the sum of all natural numbers is not actually -1/12. It’s a divergent sum. You could call it infinity.

There’s a little parlor trick that maths teachers like to perform where they do algebraic manipulation on a simple formula, eventually cancelling out the variables and arriving at some absurd statement like 1=2. The game is for the students to figure out what went wrong.

The trick is always that at some point, snuck into the progression, you ended up dividing something by “(X-X)” before moving on, seemingly without violating any algebraic rules. Very astute students (or ones who were warned by students from earlier classes haha) will notice that right at that point in time, you are in fact attempting to divide by zero, which is not possible.

So the reason you ended up with 1=2 is because you applied rules to something which they definitionally cannot apply to. At that point, the equation became undefined.

…the funny thing though, is you were able to just…continue. And get something to come out. Now, in this case, that thing was utter nonsense. An amusement for children to help teach them of various pitfalls they might fall into when playing with numbers.

But what if you were one of the most brilliant mathematicians who ever lived, and you were concerning yourself with questions such as,

“What would happen if I took [1 + 2 + 3 + 4+ 5….], and subtracted [1 + 1/2 + 1/3 + 1/4 + 1/5…]”

Now, those are both divergent sums. So we could just call them both infinity. But the second infinity just kind of…feels smaller, doesn’t it? It feels like you should be able to just…perform some type of operation and get…something to come out.

It wouldn’t be “correct” to do so, but this is basically what Ramanujan did. Illegal math. With a nonsense output of negative -1/12.

The funny thing though is that this “nonsense output” is actually now a cornerstone of quantum mechanics. It turns out we subtract diverging infinites from each other literally all the time, even just by walking around, and that pesky little -1/12 trick has proven to be consistently useful. Astonishing.

He died a preventable death at 32. Imagine what the world might have looked like today if only he could have dreamed a little longer, asked more impossible questions, and broken more rules. Specifically he died after a bout of dysentery, in case anyone is confused why they’re reading all this in the shit posting community

Belt Squats (lemmy.world)

About a month ago I posted excitedly that my gym had installed a new plate loaded belt squat machine.

I was eager to program it in, and now finally having had the chance to use it, wow!

It’s very comfortable, once you find a good angle. At first, my instinct was to sit very far back and upright to make it more like a hack squat motion. This provided a great quad stimulus, but the belt actually applied a ton of unwanted pressure to the inner thighs, and my training partner and I both ended up with big bruises on our adductors lol.

So the following week, we stepped forward, and angled our torsos to mimic a traditional squat posture. Despite this, the belt continues to dramatically reduce pressure on the back compared to a barbell squat, which is great. The belt and pulley also has much more room between your legs, so it glides freely without causing any bruising.

After finding my flow with the machine, I Iove it!

I’m someone who prides myself on being able to bring sets of heavy barbel squats to failure, but it has its downsides. For one, it’s just very mentally demanding, and there is a fear factor to overcome. Setting the weight down on the safeties after concentric failure is highly technical and while I believe it’s worth learning and practicing, it’s something I hesitate to teach others.

But the belt squat? Forget about it lol, you got one more! Take every heavy set to failure with no fear in your heart. The machine is also very easy to spot- you basically just stand opposite the person and deadlift the plates up. With that in mind, it’s actually also an amazing machine to do some super maximal eccentrics as an intensity variation. Once you hit failure, have your spotter minimally help you out of the hole, then do another super slow eccentric.

In that manner, it has several big advantages over a leg press/hack squat. I really haven’t found a way to meaningfully help someone out of the hole in a leg press. The belt squat also allows for complete freedom of motion, so it should work well for every body type.

All in all, 10/10! Very excited to progress with it for the rest of this program. It can also be used for many other exercises, such as RDLs, rows, shrugs, and more. I’ve taken to using it for standing calf press, which looks quite odd but is very effective. Since this is not an advertisement I don’t want to name the machine, but I will mention the plates travel directly up and down a tower, and it has a 1:1 weight ratio throughout the range of motion. Many other machines use a large lever to move the weight with a variable force curve, so I can’t comment on that style

lol. They can’t hear the difference even with the most expensive equipment. The resultant signal from decompressing a FLAC phase cancels with the original signal if you invert it. Meaning they are indeed 100% identical. Lossless, dare I say.

Literally all it does as a file format is merge data that is identical in the left and right channel, so as not to store that information twice. You can see this for yourself by trying to compress tracks that have totally different/identical L and R channels, and seeing how much they compress if at all

I started seeing cakes appear on people’s usernames, and I realized that it’s been a full year now since the great debacle through which many of us discovered lemmy.

Seeing them all start to pop up at once has made me a bit nostalgic. Memmy was such an exciting and important project during that time, I believe for many people it is the reason they stuck with lemmy in the long term.

So, cheers to the devs, and to anyone who still checks on this community from time to time when memmy crosses their mind.

Three main reasons

Firstly, it does make you sweat more, which reduces your weight (temporarily). It’s common for people in sports that require a weigh-in to do this and also partially dehydrate themselves before they are weighed to make their weight class.

Secondly, it’s done by people trying to lose weight in general who have heard about the first group and incorrectly believe inducing sweat this way will speed up their weight loss. The exact opposite is true: by intentionally overheating yourself, you actually reduce the effectiveness of your workout, making your fitness goals harder to achieve in the long run. There are tons of myths like this that seem intuitive but hold a lot of people back.

Thirdly, people are just self-conscious sometimes and cover up their body

So, I noticed that a couple of my image uploads made using Voyager now just show a “?” graphic. Looking around this community, I’m seeing a lot of other people’s posts are like that too.

In other apps and via browser, the images are also missing. Is anyone else experiencing this/do we know what’s happening?

I noticed while scrolling All that whenever these posts are displayed, the app lags out significantly, but then returns to normal a few seconds after they’re off screen.

I suspect it’s actually just the top one because it’s a gif. Running latest test test flight version

I actually saw that happen in real time, did we confirm it was an admin action?

Behavior started a few updates ago for me. If I go to answer a text or check any other app, when I come back to Memmy the app won’t let me click on posts for 10-20 seconds

Lemmy.world was experiencing authentication issues yesterday, making it difficult to comment and vote.

These issues were resolved some hours ago when lemmy.world updated to 18.02, but you may still be experiencing issues with your account on third party apps such as memmy.

If so, everything will start working normally if you remove your account from the app and add it again! Possibly just reinstalling will also achieve the same thing, but I haven’t tested that personally.

It feels weird having it there in big bold letters all the time. I sometimes want to show someone a post or talk about lemmy in general, but I’m apprehensive about them learning my account name.

In Apollo, there was this really interesting feature that let you disable the gestures for voting/replying/etc. If you did so, then you could use the entire screen to navigate between posts instead of needing to swipe all the way from the side.

I struggle with a repetitive stress injury and this feature helped me a lot! I managed to grab a screenshot of the exact setting before Apollo shut down. It would be awesome if something similar could be implemented in Memmy

I’ve been sleeping on the same one for a few years but it’s become really lumpy. I don’t mind spending a little money, but are the modern “high tech” pillows really worth it?
