I'm a pretty proficient cyclist (lifetime mileage in the tens of thousands) but there have still been a handful of incidents where I've been very grateful to have had a helmet. It might be the case that helmets are a net negative for casual riders. But whenever I've done a spontaneous unplanned dismount at 20mph I didn't find that knowing how to fall helped me much.

> But whenever I've done a spontaneous unplanned dismount at 20mph I didn't find that knowing how to fall helped me much.

What was the circumstances (type of road and type of bike)? Have you touched the ground with any other parts of body except of palms, elbows and knees? If yes then consider to keep learning how to fall because your falling skill is not that proficient. If not then the helmet was not that useful.

Some of my peers are deep into running. I don’t get it. Running is sometimes fun for me but most often painful. Then I overheard one of them (the fittest) say to a budding runner that he [should] do mostly easy sessions. Okay what’s easy to him? He said that so slow that it can feel awkward and unnatural. What? Then I searched around and found out about Zone 2 and how you should do most of your work in that zone when…

Yes, most of experienced runners' running is at a conversational pace, often literally (this is why running groups are popular). To explain why harder isn't better: improvement in running comes only a little from muscular strength, so that mental model is bad. Improvement is primarily based on aerobic development of the cardiovascular system. This is your body's ability to burn mostly-fat with oxygen, deliver the ene…

Yes....

I have been exclusively an anaerobic athlete for the past two years and my aerobic fitness has dropped to a shockingly low level. But I am oddly comfortable at 180-190bpm

I am slowly building in more aerobic cardio into my training but man cardio is just such a chore for me. It's always the first to go so it takes constant maintenance and it's time consuming...

What’s the best way to accurately measure one’s VO2 max, or at least ballpark it sufficiently so that you can track improvement over time without it being lost in measurement noise?

Do you need to measure VO2 max specifically? If your form of exercise is jogging/running, you will easily be able to tell if you're improving by tracking distance and time of your runs. If you want to be precise, you can e.g. race a timed 5k once per month under the same conditions. But if you're a beginner, you won't need that to be able to tell you're improving, just the feel of difficulty to maintain a certain pace will change noticeably.

As someone else mentioned, a classic poor man's test of VO2 max is simply to time trial a set amount, such as seeing how far you can run in 10 minutes, and use a calculator. So the same thing with extra steps.

Your username isn't? I once jumped a curb and scraped off half the skin on my palms.

> the skin on my palms.

The down-voted comment of mine tells that gloves are far more useful than helmet for a bicycle rider. But I know I have messed with the holy cow so c'est la vie.

I watch all streaming shows on a rowing machine with not-so-high speed and not-so-high resistance. The show keeps me entertained and sometimes I even forget that I'm rowing. Previously I did that with an iPad 12.9" next to the machine, but I've just started watching shows on the Quest 3 and that's way better.

Uff that must get hot under the Quest.

I didn't try exercising with it, but, Quest 2 was getting too hot for me even after a short while playing Beat Saber for example. Quest 3 is much better in that aspect. I can actually keep it on for long durations, and heat isn't a problem at all.

Helmets aren’t uncomfortable if you try them before buying them. There are different shapes, materials, sizes and settings. About finding my helmet, I always attach it together with the bike with the U lock. Unless I’m parked in a secure place where I let it hang on the handlebars. I’m not especially advocating for mandatory helmets and I’m the first to say absence of helmet shouldn’t prevent you to ride, but if you…

Come on man, I have never rode a bicycle more expensive than $100 despite riding at least 5000km annually. I bet that your helmet costs more than all of my 3 bicycles.

Instead, people try to fix it with antidepressants, benzodiazepines or something else. It feels a bit like the US approach to pain management – instead of massages or physical therapy, some opioid pill is cheaper to prescribe.

I dislike this black n white rhetoric from both sides. "Just do some workout" - "no this doesn't work for me". Yes, workout does help, but mental illness is still real. Both sides should try to be more sensitive and more understanding in my opinion. I can't fix my social anxiety through workout. But I sure can feel better about myself when doing it and then approach those anxieties with more confidence, but the anxie…

I'm speaking from experience regarding mental illnesses and exercise. And I never discounted medication. Just that exercise is critically underprescribed, I'm fairly sure it would work better for milder cases compared to meds. Not to mention the other health benefits listed in the thread.

Same way an opioid pill is still prescribed in cases of cancer or severe pain. Just that there are probably better, milder alternatives that don't have as many side effects that could fit a lot of these people with milder problems.

Not sure about this one. When in my fourties I looked in the mirror one day and thought "my god man you have piled on a few pounds lately". I immediately went out and joined a gym for a bit of indoor running So, I went weekly for an hour or two. I thoroughly enjoyed it. My I'm not sure! I was happily running along on my treadmill one day, hreart rate at a constant 125bpm, whe suddenly there was an almighty commotion…

Its not cardiovasuclar, but the top 2 causes of death in the US are tied to obesity, which takes zero time to reduce. You just have to not eat, which is actually time positive. Most humans are just incredibly bad at impulse control.

There was a relatively recent study that found that BMR has actually been dropping over the last 30 years. The difference in men was large enough (7% iirc) that it would explain most of the obesity epidemic. Why it's dropping is still a n mystery though. Nevertheless, the solution is still the same: eat less. The study: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10445668/

lack of physical activity (sedentary job + sedentary entertainment) + shitty diet = lower testosterone

lower testosterone = lower lean body mass (you gain tens of pounds of muscle on TRT even without exercising)

lower lean body mass = lower BMR. an average doughy 200 pound guy and a 200 pound athlete have vastly different caloric requirements.

Fortunately, this seems relatively simple to change (compared to other things with this magnitude of impact). It was a transformative experience to go from 40 VO2max to 57 (as reported by Apple Watch, and losing 30lbs on the way) over the past 12 months. The best part about it is that I didn't even have to give up anything - the extra energy I gained from 90-120 minutes of aerobics per day also had the effect of maki…

I love these kinds of posts. They are ridiculous. First: > Fortunately, this seems relatively simple to change Second: > the extra energy I gained from 90-120 minutes of aerobics per day Are you joking? You are asking average people to commit to 90-120 of c-v exercise per day? So, 7 days per week? This stuff is nonsense. Most people would quit after a week. I guess 99% of people could not sustain this for more than 3…
