That's why I wish they were more explicit when defining the kind of exercise the subjects were engaged in. My comment was primarily from personal experience.

That's why I wish they were more explicit when defining the kind of exercise the subjects were engaged in. My comment was primarily from personal experience. When I did my anaerobic exercise when I used to train, it was heavily anaerobic, where I would do a lot of short bursts of heavy lifting. Later I transitioned to primarily focus on aerobic, where I did a lot of distance swimming. So I think I had a good amount of both extremes to at least provide some insights. Everyone's experience will likely be slightly different. My hunch, though, is a lot of people who do lifting still get aerobic benefits because they're not training as intensely. So I think I'm speaking more about the extremes of the two types of exercise and not a middle ground.
