The Nike Vaporfly 4% wasn’t shy about how much of a boost it claimed to give runners: the promise was right there in the name.

A new study finds that using social media for 30min before workout each day causes mental fatigue and ultimately leads to worse performance after 3 weeks. Is it a real effect? It's plausible, but look carefully at the individual variation in responses: https://t.co/zUYvpmYbEe
