Is strength training cardio?

Some times strength training can have a cardio element to it if you keep up a pace that gets your heart rate up consistently.

I think your logic is flawed though. Deadlifting 2x your bodyweight seems like a much greater feat than running a 33 minute 5k.

possibly, but that depends on a few factors, like age, sex, weight. It's taken me about 5 months to work up to ~2x BW deadlift, but running a 5k in that time is impossible for me and would probably take me a long time to get to that

Exactly! I will probably never be able to deadlift 2x my bodyweight, but I ran 5k in 27 minutes shortly after finishing the C25K program.

And no matter how long I lift heavy or train for running, I will probably never be good at swimming laps. LOL

Looks like you got a "C" from Runner's World. I'd say the dead lift over 2x body weight is definitely a bigger achievement

Your age-graded score is the ratio of the approximate world-record time for your age and gender divided by your actual time.

To score 100% you would need a time of 14:31

I used their calculator and got an F. 48 yo male 5k time 28:39 (that was my time this morning):

I like yours better. But I think you entered 33:40:00 which would result in the numbers you posted. But that's 33 hours, 40 minutes, 0 seconds. I might be able to do a marathon in that time.

That's equivalent to a 290 lbs DL for me. Not that impressive, to be sure.

To match my 480 deadlift @ 198 body weight, I would have to run a 17 minute 5k. I concede my original hypothesis is invalid.

Oops, you are right, can you tell I'm not a runner? But yeah, I think the deadlift x2 bodyweight is much more of a standard and more impressive than your 5k.

Comparing just anyone's time on a 5k or 10k is like comparing just anyone's dead lift, and most thin people with low bodyfat % will have a relatively OK to good number on a long distance race, just like most 350lbers will have a relatively OK to impressive looking deadlift if you just take raw numbers with minimal training.

I don't really equate 5k or 10k to just general "aerobic" fitness either, that's specialized long distance running. As you stretch out the distance, humans can even compete with horses, so does that make horses "not as aerobically fit"? Even just with humans, the more muscle mass you have in the upper body, and the "fitter" someone is in this way, the lower you are going to "score" on the long distance running. Just imagine Arnold running a 10k... Even Bolt is going to start to suffer on a 5 or 10k, and you can't say he's not aerobically fit.

So I wasnt really saying your hypothesis is invalid, just the comparison was bad, and that there are different types of aerobically fit. Yes you are getting some aerobic fitness with weightlifting, for shorter duration aerobic activities. If you want to compare long distance aerobic fitness, probably only your bodyfat reduction is "helping" you, and muscle gain from lifting is "hurting" you.

interesting how the more you run, the better your times seem to get.

must be from lifting.
