Video: JJ Watt’s workout routine shows what it takes to be a beast

"Everybody wants to be a beast, until it comes time to do what beasts do."

JJ Watt certainly qualifies as a beast, and the reigning NFL defensive player of the year has shown a glimpse of the relentless workout regimen required to reach the top of America's biggest sport. The Houston Texans lineman allowed Men's Health magazine film one of his 90-minute training sessions ahead of the new season, which starts tonight, and it's exhausting just watching Watt go through the gruelling exercises. Sure what's the point of a kettle bell unless you've got a resistance band to go with it? The terrifying thing is that Watt classed this workout as light (!), given it involved no heavy lifting (Watt benches 400lbs) or tyre flips.
