Interesting that the Landrigan et al. review hereisonehand cited showed no effect of strength training on working memory; the review here reported no effect of aerobic exercise on working memory, but did report benefit from combined strength training and aerobic. Feels a bit fishy that each would have no effect individually, yet have an effect when combined.
My model is something like: “these effects dance around the edge of significance and have a bunch of uncontrolled variables that differ between studies, so it shouldn’t be surprising that the results aren’t consistent.” Now, that might cause you lower your credence in the whole endeavor, which in fact I do.

I wonder if hereisonehand would be interested in a repeat performance.
