So he's being trained by his brother and his wife.
Erik Manoah Jr. and Natalie Orantes.
Looks like Erik started this business with Natalie in 2020, while still trying on his MiLB career.
Erik is a minor league pitcher who has never been able to throw strikes, so I'm not sure he has any merit as a personal trainer aside from his pitching experience and being an athlete.
Natalie is a Registered Dietician, Licensed Dietitian/Nutritionist, and Certified Personal Trainer from what I can see. So she has some merits.
Maybe, just maybe, they can save him.
But he does not appear to be at any kind of advanced or progressive baseball training compound. Like, he's doing instragram exercises at a mom and pop gym.
