Halle Berry is making 50 look good!

The actress – who celebrated her birthday on Aug. 14 – is showing that age really is just a number with a sexy bikini snap she shared on her Instagram.

“BTS on my last shoot of the summer,” Berry captioned the photo she posted on Tuesday, in which she flaunts her incredibly toned stomach in a strappy black two-piece.

Berry gave a peak into her bikini workout routine in May when she posted a video on Instagram of a beach workout she did with her trainer, Nat Bardonnet. In the clip, Berry holds a plank position and reaches out to tap alternating hands with Bardonnet, who is also holding a plank.

Bardonnet previously told PEOPLE that she works out with Berry for 30-minute power workouts at least three times a week. Their cross-training sessions include push-ups, weight training and planks.

“The way I push Halle, not many people would be able to last,” said Bardonnet at the time. “She always has great energy and a great smile. Whatever curveball I throw at her, she can take.”
