Pittsburgh Steelers linebacker James Harrison frequently shares videos of his crazy workouts on Instagram, and in just about every one, he's wearing the same gray sweatsuit.
Teammate Maurkice Pouncey had Harrison explain why Tuesday (while working out, of course) and it's pretty hilarious:
They been asking me questions about why I wear a sweatsuit to work out. The whole reason I wear a sweatsuit to work out is so they can't see my arms. I don't want to disturb people from coming in here to work out just because my arms are so damn big. That's why I wear a sweatsuit.
