Athletes like to say they are trying to improve all the time. It is mostly lip service, as all they’re really doing is tweaking their foot placement or slightly modifying their arm delivery. They are not rearranging their daily lives to make these adjustments.

But the New York Giants star wide receiver Odell Beckham Jr. is carrying out an unusual tactic when he’s not on the field, one that few athletes have even considered. He’s living his life as a secret lefty.

Beckham’s right hand is perhaps the most impressive in sports these days. The outstretched one-pawed catch he made with it against the Dallas Cowboys last season is widely considered one of the most athletic plays in NFL history. Since then, Beckham reached 150 receptions faster than any player in NFL history. Virtually any record that involves receiving performances to start a career belongs to Beckham. His one-handed catches, predominantly made with his right hand, have quickly shot him to superstardom at age 23.

Like 90% of humans, he’s right handed. And although he’s shown talent with both hands, he decided that wasn’t enough. So he changed his habits, and he started with the most mundane of tasks.

“Brushing my teeth with my left hand—this is going to help me,” Beckham said. “Why won’t this help me be more coordinated? You have to have [another hand] so you might as well use it.”
