"J.J. Watt is a beast" is an understatement. Last year the Houston Texans defensive end became the first player in NFL history to record 20+ quarterback sacks in a season two years in a row; and judging by his training regimen (Exhibit A), he won't be slowing down any time soon.
Recently Watt tweeted a picture of himself squatting a massive amount of weight, which we estimate at around 585 pounds. But to be clear, Watt specifies that it's "NotAMaxOutRep," implying that he performed multiple reps and/or sets.
