"Does CrossFit make sense for an NFL linebacker? No. Does an NFL linebacker's program make sense for regular people who want to be able to do everything well? No."

If you have a specific goal in your training — top-level competitive mountain biking, bodybuilding, a 600-pound deadlift — then CrossFit isn't for you. You need to specialize. If you want to be good, but not great, at a variety of athletic qualities, then CrossFit is a good option. And that's the truth.
