Across the green, Tirek twisted around into a rear lat spread. Oil and sweat gleamed in the sun. "Weak excuses for a weak form! A true bodybuilder would never let such trivial concerns stand in their way!"
Bulk shifted, gathering all his muscular mass forward into a looming front double biceps. "That body isn't your own! It's stolen and artificially enhanced - there's nothing in it to be proud of!" His namesake biceps bulged. "YEAH!"
Twilight gagged - hard. "Dear Celestia, I can smell the testosterone. How long have they been at it?"
"Three and a half hours." Applejack paused to loudly sip her drink. "Heavy casualties. Six mares an' two stallions fainted. One nosebleed. An' Big Mac snapped his back tryin' to copy them."
