Have you tried eating a snack after? Maybe you're hangry

This is actually good advice. Some people respond very, very poorly to being hungry and I've noticed some of them aren't aware of it.

Yep. I've found that feeling grumpy and irritated is a more reliable indicator that I need to eat than actually feeling hungry

Counterpoint: I am personally skeptical about the long term value of arch supports. The reason is that while they can undoubtably help with short term pain, they also inhibit strength development and introduce an unnecessary dependency (kind of like a software library). I am not disagreeing with your experience or discouraging people from using supports to deal with injuries. I am just questioning making yourself rel…

I believe you are correct and I believe that what you are expressing can be generalized - and distilled - as the following: Bracing a body part weakens that body part in the long run . Anybody who has ever had a cast on their arm knows this firsthand.

Yep. I walk barefoot everywhere I can and if not, then I wear sandals. I was having terrible pain in my feet when I was wearing “shoes with support”, which went away once I started wearing sandals and going barefoot everywhere. If I run I run with glove shoes or whatever they’re called nowadays.

> The author Daniel Lieberman has put it well: Exercise is healthy and rewarding even though it’s something we never evolved to do. We have ostensibly spent much of our evolutionary budget on the ability to run ~indefinitely no matter what. Compared to virtually any other animal, we can vastly outperform them in the most arduous environments. Our bodies are mechanically optimized for running at every level. We have c…

> Compared to virtually any other animal, we can vastly outperform them in the most arduous environments. Our bodies are mechanically optimized for running at every level. I'm not sure from where you got this because any documentary/book/article and simply real life experiences related to this subject states the opposite (take a common animal such as a dog as an example)

“Real life experience” tells me I’ll run any dog into the ground if it’s over 50F. Cooler than that? The dog still better be part of a trained sledding team.

AND YOU DON'T NEED TO RUN to start with. And if you are overweight and sedentary DON'T RUN TO GET INTO SHAPE. Walking, hiking, swimming, biking, and weight training. Mix all of it so you get cross training effects and distribute stress across many domains. Running is, by the standards of the statistical hole America is in terms of obesity, an "advanced" activity. We're talking about something that involves a stress i…

It can be really hard to get cardio without running. I still agree despite that.

It is, it is so low-cost (running shoes) and available (walk out the door).

And doing it is close to the maximum calories you will burn per unit of effort and time.

I think it's sort of reasonable in this case, given there's very little investment in running on 4 limbs, while nation states fund track and field programs to the tune of millions of dollars. That the small number of 4 limbed runners are making progress against 2 limbed runners does indicate it might allow higher peak performance. Of course, 4 limbed runners have probably already plucked the low hanging fruit in perf…

Don't sprinters start with 4 limbs on the ground? The advantage of the 4 limbs seems to be gone by the second step.

Trail runners often run with poles on up or down hills. Not sure about top speed, but from experience the poles definitely help with endurance.

I’ve read in a few places that the flat feet comes from wearing shoes that don’t allow your toes to splay, which causes the muscles that create the arch to atrophy. Not a scientist and have never had flat feet, so can’t confirm, but I recently started wearing zero drop shoes and definitely feel a healthy soreness as my feet get stronger.

Also when you run don't land flat-footed or heel-first. Land on the front part ("ball") of your foot, this lets your calf muscle absorb the shock, rather than sending the shock straight up your tibia into your knee.

This was a total game changer for me when running. I would always develop some sort of knee pain at some point but since making a very minor change to how I land my foot, I am running without any.

Make sure to start and transition slowly though as there are warnings about injuring your Achilles and other muscles in your calf if you start off too aggressively.

Walking is definitely better than sitting down all day, but that shouldn't be the goal. Weight training and more intense cardio are more important.

I walk every morning and hit 80-80% of my max heart rate for parts of it. Walking can be quite good exercise, unless you live somewhere very flat. My V02 max continues to climb steadily 0.1/week like clockwork, and no running yet. Granted, it's got a ways to go, it's just barely above average, but still, walking is working.

Re-reading what I wrote, I meant to write 80-85%

>Like someone already said: what if you get an injury going to hard at it? There's no need to go hard, even steady walking for 20 minutes a day is healthy. And recent studies show that you don't need to jog or run, walking is almost as efficient and less stressful for your joints. One of the best ways to exercise as long as you aren't a brain in a jar is to use an indoor rowing machine. Rowing will engage about 80% o…

For me I don't think walking 20 minutes a day is enough. I did more than that right after graduation. It didn't change any of the metrics usually used for measuring healthiness: my resting heart rate didn't change, my VO2max didn't change, my weight didn't change, etc. it was when I started regularly running 2 hours per week (aka around 20 minutes per day) that I started observing my health improve. YMMV.

I'd rather be outside exercising / having fun and get the occasional twisted ankle or whatever, then staying home sitting on the couch and feeling like crap. Personally the only, very minor, sports injury I have had is jamming my thumb pretty badly when my skis came off (poor bindings). Was better in a couple of weeks - no big deal. I'm 64 and started skiing 6-7 years ago, now happily going down blacks. I did partial…

Now tell me how many years extra you live compared to the you that just eats healthy but doesn't exercise outside of 3000 steps a day (not bedridden, not intentionally exercising)

I think it's more about quality of life rather than extending it - enjoying outdoor activities (skiing is a blast!), enjoying looking good and being in shape, able to do all my own yard work and snow shovelling etc without it being an effort.

Now, while I choose to do things that I enjoy (and the skiing is purely for enjoyment, even though it requires a lot of energy), I will say that part of the motivation for wanting to keep in good shape is seeing what happened to my Dad who had an office job (professor) and didn't exercise at all other than a bit of walking to the grocery store etc, and in his old age had all sorts of pinched nerve and mobility issues due to lack of muscle tone and strength, and realized it was too late to do anything about it.
