They also looked at cancer mortality here, and the cancer risk had a different pattern, which was interesting.

The biggest apparent cancer benefits showed up at the lower levels

of resistance training, not at the higher levels as you might think.

So if you lift weights for less than 30 minutes per week, that was associated with a 21% lower cancer mortality.

That was very interesting at least.

I'm not sure what to conclude about that.

If you did 30 to 59 minutes a week,

that was associated with an 18% lower cancer mortality.

So it dipped down a little bit.

But if you do more than that, it does not keep pushing the cancer mortality lower.

It kind of peaks at about 30 minutes or less a week for the maximal cancer protection, apparently.

So I just want to throw that out there.

Oh, I did not see that in the study.

These were health professionals.

So I would suspect that this is just something that was part of their lifestyle initially, but I didn't see any solid numbers on that.

And that's the other big problem with this is that it was self-reporting, which you know is much more problematic than, say, like the cardio study I talked about a while ago.

They actually had monitors on.

All right, so what about people who did both weight training and cardio?

I'm sure you would guess that the results would be better, obviously, right?

But how much better if you do both?
