There may be a small number of people for whom strenuous exercise right before sleep doesn't interfere, but a more likely explanation in my mind is broscience.

There may be a small number of people for whom strenuous exercise right before sleep doesn't interfere, but a more likely explanation in my mind is broscience. The weightlifting community is especially susceptible to training methodologies which are suboptimal but fit the identity they're performing. Are these people really scientifically evaluating the affect of intense exercise close to bedtime, or are they working backwards from what _feels_ the most "manly"?
