> From what I gather, aerobic exercise...

That was my impression as well after doing some research in this area a while back. Although I looked specifically at longevity and cardiovascular studies there was a peak benefit at about 2hrs per week after which virtually no more benefits were observed.

2 hrs a week of intensive aerobic exercise sounds like an easy to remember target if that's what research shows.

[wild_preference]

I wouldn't stop at two hours just because there's no additional benefit that manifested in a study on some super-specific outcome.

You probably care about other benefits as well.

What constitutes "intensive"?

I finally got a heart monitor. So far, I get into "zone 4" for a few minutes every day. Zone 5? Not so much...

Weight training tends to be moderately cardiovascular. Not an out-and-out replacement for cardio, but your heart will be pumping hard at higher weights/reps. Same thing for a long session in a hot sauna. Just throwing some nearly-as-good alternatives out there for people who hate treadmills.

[gmiller123456]

Just to throw in some new terms, weight training tends to be more anaerobic, where things like distance running are more aerobic (where oxygen provides most of the energy). It's not an either/or, but more of a scale progressing from aerobic to anaerobic. Lifting more weight is generally more anaerobic than lifting less weight. And the downside of anaerobic exercise is that you can generally only do it for short periods of time.

Since I don't have a Science subscription, I can only read the summary, and they do not explain what type of exercise they required the mice do. So if someone with access can clarify, please do. But from what I know of similar "cleaning out" studies, the exercise is generally distance running. So weightlifting for a short period of time is probably not going to give you the benefit this study refers to, even if you're burning the same number (or more) calories, because you didn't do it for as long of a period of time.

In particular, dead lifts wind me every time. After a set I feel like I just ran up a few flights of stairs. Other lifts not as much, but man I have respect for the dead lift. Works damn near every muscle in your body at the same time.

[justinator]

Yeah, it's not aerobic at all, unless you're doing 1 set of 100,000.

I hate treadmills, but going for a bike ride or a walk is awesome. I don't know why people go to the gym to run...
