How Lady Gaga Got in Shape for Her Super Bowl Halftime Performance

The singer says she trained using TRX suspension training.

Over the past several months, the singer worked tirelessly on both her body and vocals at the same time to ensure a flawless show.

"I'm singing the show while I'm doing it," she said. "Because the show is full-on cardio ... it's cardio while singing."

Gaga's trainer, Harley Pasternak, posted a photo of her pre-game warm up on Sunday that showed the singer in her full Super Bowl costume while using TRX bands, a portable athletic suspension training system.

"When you’re singing you’re projecting so you almost are forced into this upright posture and as you’re singing you’re activating your core so you’re actually getting stronger," Pata said today on "GMA." "It’s like planking but it’s more fun because you’re singing."

She continued, "Anybody can do it. You don’t have to be a great singer. If you find yourself alone and you want to belt out a tune, then do it because you’ll get stronger as a result."
