Series 5 does it post every Cardio exercise

According to Apple[0] it is only after the specific activities of: Outdoor Walk, Outdoor Run, and Hiking. Which explains why my estimated VO2 max goes down significantly in the winter months when I'm mainly doing cardio indoors and only taking leisurely walks with the dog outdoors.

I wonder why they can’t track cardio indoors. Perhaps because the watch doesn’t link up to most / any treadmills and is generally totally inaccurate with respect to distance and speed?

If anyone wants a shortcut to an extremely good workout, look into rowing (MAKE SURE you learn proper form!). I focus on "maxing out" sets of 500m since it correlates well to basketball cardio, and I have infinite cardio even in my mid 30's.

I’ve recently taken up the erg machine doing an hour a day, and it’s been phenomenal. The one problem I’m faced with is canabalizing my chest muscles for increased legs and back. Eating enough calories is actually impossible.

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…

2 hours a day is a ridiculous amount

There’s amusing statistics that show that if you’re out of shape and a smoker, you get a bigger bang for the buck from getting in shape first than quitting smoking. Disclaimer: not an endorsement of smoking.

reminds me of the bicycle helmet stuff. There was a ted talk that said bicycle helmet laws would kill more people than save. The reasoning was preventing people from riding would also prevent increased fitness, and more lives were lost from that than saved from accidents. EDIT: I think this one: https://www.youtube.com/watch?v=07o-TASvIxY

More cyclists on the road makes it safer for cyclists. Combined with risk compensation, this seems enough to make helmet laws a net negative. Well studied. Wear a helmet though, they work!

I've been walking every day and lifting weights 2x a week. I feel good so far but the hard part is doing it for years and through seasons (both literal and figurative).

You should add some diversity in your activities and you will perhaps identify some that you enjoy more at a given time.

Sorta related: My boomer mother is experiencing cognitive decline, probably the early stages of dementia. Her doctor said that as we age, blood vessels in the brain can get starved for blood and eventually dry up, making them useless. This is the biological explanation of her loss of memory and difficulty thinking. I asked if there's anything that can be done to at least slow this decline. She said the best medicine for the brain is physical exercise; it forces blood into the areas of the brain where blood vessels are at risk, prolonging its well-being.

BTW, I asked the doctor how much exercise is enough. Her response: If you smell the same when you're done exercising as when you started, it's not enough. I found that both humorous and helpful.

Disclaimer: I'm not a doctor or expert. If a loved-one is experiencing memory loss or difficulty thinking, see a doctor.

Weird that people seem to assert that causality is not established? There are hundreds to thousands of studies that show that pretty much all markers for mortality and morbidity go down with excercise, i.e. put someone regulalrly on a treadmill for a couple of month and pretty much all health markers improve.

People implying that the study shows only correlation really don't seem to understand how we establish causality in science.

That sounds like the sort of stuff that is completely correct. Low fitness is significantly more risky than smoking. (I am not suggesting that anyone start or continue smoking.) https://peterattiamd.com/all-things-vo2-max/

Nicotine suppresses appetite and is also a potent nootropic. Consuming nicotine in losenge or gum form doesn't have any of the ill effects of smoking or vaping. It's also virtually impossible for a nicotine naive person to become addicted through losenges.

always wondered what the effects on the gums would be since the saliva concentration would be higher with gums/lozenges and it’s primarily surface absorption vs. airborne nicotine.

It's also absolutely amazing for mental health. It's a shame it isn't considered a first line of treatment for mental health because it's super effective (and free).

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.
