This isn’t the first time the 50-year-old singer has shown off the flawless abs she's worked so hard for; Lopez has posted dozens of abs photos to her own account. So how exactly does she get such a chiseled midsection? 

One of J.Lo’s trainers, David Kirsch, previously shared with Health one of her go-to moves: side-plank oblique crunches.

“It’s perfect for when you need to focus on shaping and toning not only the obliques but the entire core,” he said.  

Another of J.Lo’s personal trainers, Tracy Anderson, previously revealed to Health some of the superstar’s other moves, including a flexed knee pull and arabesque, a lifting side kick, and a shoulder balance with leg pull. You can see the full workout in this video.
