Arjun Raghavan
Runs the deep dives and decides which ones are worth the six weeks they take. Writes the training-science pieces and reviews anything that ends in a prescription a reader might act on, on the principle that the sentence telling someone how to train is the one most likely to be wrong. Keeps the limitations chapter in every article and argues for making it longer.
