One thing I wonder too is how can you do a controlled, randomized, DOUBLE-BLINDED study for exercise. Is it even possible?

The researchers could be blinded but there's no way to blind the person doing the exercise. There is no "placebo" exercise that you could do.

How might this bias the results of exercise studies?
