Bryce Harper is already making headlines for packing on 20 pounds this offseason and reporting to spring training in linebacker shape. Now, via his new Under Armour commercial, the 20-year-old Washington Nationals phenom, is letting the world in on his training secret: glow-in-the-dark weight lifting.
Pay close attention to 26-second mark.
Considering he's a 20-year-old from Las Vegas, we bet Harper is also jamming to Skrillex, having a full-on neon/EDM/iron-pumping solo rave while Snapchatting with John Cena.
