One look at OBJ and you’d never think he’s the type of guy who hates vegetables and fish and refuses to drink water. Yet all those things are reportedly true, or at least they were at one point in his life. It’s even been said that he sometimes needs to take his fluids via intravenous injection, representing one serious aversion to H2O!

An athlete’s fitness regimen is usually as good as the person overseeing it. That responsibility falls to Jamal Liggin, i.e. Odell Beckham’s personal trainer. In Liggin’s own words: “Our foundation is speed, but the program isn’t just speed and strength. It’s also vision and awareness. Footwork and quickness. All of it works together.”

During both the on and off-seasons, OBJ’s training consists of resistance speedwork. That speedwork gets extra brutal during the off-season, in particular, when OBJ and Liggin take the action onto the sand. It’s there that he performs footwork exercises, tennis ball drills, and sprints. Inside the gym, he gets busy with the resistance bands or performs pool exercises.

If OBJ is famous for one thing on the field, it’s his nifty one-handed catching skills. That might be why Liggin’s tennis ball drill—which features OBJ catching various tennis balls with one hand—went viral in 2016.

Bringing new meaning to the concept of footwork drills, OBJ is known to execute his wearing no shoes. Taking verbal cues from Liggin, the football star performs ladders or sprints. All the while, OBJ must keep an eye out for flying tennis balls, tossed by Liggin at various speeds.

OBJ is supremely dedicated when it comes to his yoga and Pilates. Thanks to their emphasis on stretching and flexibility, these methods keep the wide receiver light on his feet and perpetually ready for action. Don’t knock it until you try it.

By his own admission, Beckham isn’t some sort of iron man, but don’t take that to mean he doesn’t perform massive amounts of strength training. On the contrary, his upper body workouts are as intense as they are effective.
