The Apple watch has a decent cardio fitness monitor. The absolute values aren't precise (since it uses VO2Max estimates, which is really only accurate if you're doing a metabolic stress test), but it's good to keep an eye on trends.

Cardio still counts even if you don't measure it and share it with Apple.

Does Apple get your cardio data? It's my understanding is that is encrypted, even when it goes to iCloud for backup.

The poor VO2Max estimates on the Apple Watch is why I'm phasing out of wearing one. I track my actual VO2Max measurements in Apple Health via a shortcut, and I don't need a daily made-up number messing up my data.

How often do you do metabolic stress tests?

Pretty sure Dexa scans and VO2Max tests are HSA/FSA eligible.

What about it? It’s still coming out of my pocket, albeit untaxed.

I was just trying to save people some money.

As the OP mentioned, absolute numbers are garbage, but trends are useful. Once a year just get an actual VO2Max test to peg the watch values too.

The trends are garbage too. According to my watch my VO2Max has swung wildly between 55 and 45 over the last year, while every other measurement points to my fitness staying mostly steady.

I find that my scores are mostly determined by how well I sleep the night before I do the workout.

Wait-to-hip ratio is an accurate measurement of cardio-respiratory capacity ?

Morbidity and mortality, which is what the article's title is about.

The article is about how morbidity and mortality relate to cardiovascular fitness. The fact that waist to hip ratio also is related to morbidity and mortality is a bit irrelevant in that specific context. One can imagine a person who vigorously rows every morning for 45 minutes and has a high cardiovascular fitness, but who also has a very poor diet and is thus fat.

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

There's real data out there that while a helmet has better survival rates than not; but cars give more room to bicycles without helmets, so the incident rate is lower.

This sounds ridiculous until you go to Amsterdam see that few wear helmets there. And everyone is cycling. They might be more inclined to cycle because they don’t need to wear a helmet. After years of cycling with helmet you get so used to it and it doesn’t bother you. But how many skip the bike because they never got used to wearing a helmet?

more like because it’s safe and there are penalties for injuring pedestrians and cyclists, and because the infrastructure is great.

not riding a bike because a helmet is ??uncomfortable?? is ridiculous and probably self-selecting

It only takes a few months to make substantial gains in c-v fitness.

Define substantial. I find that incredible. EDIT: Now that I've seen the replies, I realize that this is from a very low baseline. I'm personally going to the gym four to five days a week already and my own cardiovascular fitness has not seen much of an improvement in many months.

n=1, but I can personally attest to going from average sedentary 29 year old to marathon running shape in roughly 3 weeks of continuous hiking 8 to 10 hours a day in the Appalachian mountains with a pack that was about 35% of my body weight.

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.

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?

Probably a cooper test -- run as far as you can in 12 mins. Then there is a formula to convert that distance to vo2 max.
