At 5'10" and 186 pounds, Antonio Brown is on the smaller side for a wide receiver. But when it comes to natural talent, he towers over the rest of the NFL.

Possessing an electric combination of speed, strength, agility, and hand-eye coordination, the Pittsburgh Steelers star has rewritten the record books over the last few seasons, setting a new mark for the most receptions by any player over a four-year span with an astonishing 481 catches from 2013-2016.

That production has helped the Steelers offense become one of the most offenses in the NFL, and it's made Brown an elite star. But while natural ability has a huge role in Brown’s rise, his hard work off the field and in the weight room has paid major dividends.

“You've got to take care of your body—you’ve got to make those commitments to get in the gym, and make sure you make those commitments to working out and staying strong,” Brown told Men’s Fitness during the 2016 season. “I try to keep my in-season workouts as intense as the offseason, making sure my feet are in shape, and make sure I'm still getting the same lifts.”

Here’s a small sample of what Brown can do in the weight room:

Brown uses a wide range of workouts and training techniques to keep himself in shape. “I love doing a lot of balance exercises and moves that fire my glutes,” Brown said. “I like all types of stuff—bench press, shoulder press, flys, traps, triceps, biceps—it all helps me on the field.”

All that hard work is why he was able to muscle through three Baltimore Ravens players—safety Matt Elam, safety Eric Weddle, and linebacker Zach Orr, a combined 640 pounds—to score the game-winning touchdown in Week 16 and help the Steelers clinch the AFC North division. With the score tied 24-24 with just nine seconds left and the division title on the line, Brown caught the ball at the 2-yard line and refused to be stopped:

As he showed after the Steelers’ win over the Kansas City Chiefs in the divisional round of the playoffs when he controversially live-streamed coach Mike Tomlin’s post-game speech, Brown loves social media—but he uses it for more than just blowing up his coach’s spot. Much like super strong teammate James Harrison—who crushes massive weight in the gym constantly—Brown enjoys sharing his workouts and training sessions online.
