Antonio Brown Is Now Training With LeBron and D.Wade's Trainer, Looks To Be in Incredible Shape

Antonio Brown has began working with David Alexander, the owner of DBC Fitness in Miami. Alexander's client list includes LeBron James and Dwyane Wade.

Thanks to his recent four-year, $68 million contract extension with the Pittsburgh Steelers, Antonio Brown is now the highest-paid receiver in the NFL.

That kind of a payday might have led a lesser man to an offseason filled with extravagant partying and exotic vacations, but Brown has been training like a madman ever since he inked his deal.

Earlier this week, Brown started training with David Alexander, the owner of DBC Fitness in Miami. Alexander's client list is impressive. He has worked extensively with athletes such as Dwyane Wade, LeBron James, Ben Simmons and Carlos Hyde.

Alexander shares plenty of videos of his clients on Instagram, allowing us to see some of the unique drills and exercises he puts them through. Check out some of the highlights from AB's recent workouts:

That first exercise is what's known as a Rear-Foot-Elevated Split Squat Jump. It strengthens the quads and glutes like a typical Split Squat; but the jump also turns it into a plyometric movement, which trains the muscles to absorb landing force and immediately contract into another jump—the key to developing explosive power. This is a great exercise for building explosiveness, and AB is getting some absolutely absurd height on his reps.

The second exercise is a variation of a Slide Board Speed Skater, an excellent drill for building hip strength and stability and balance. Catching a football as he slides increases the difficulty and recruits more of the muscles in AB's core.

The final exercise is a speed and agility drill. Brown performs a number of footwork drills as he weaves his way through several flags. This obviously improves his footwork and agility, but notice how those flags are slanted. That forces Brown to stay low while he changes directions, greatly improving the efficiency of his cuts.
