Jessica Biel shared a fun video with her two million followers on Instagram of her doing an acrobatic backflip while on vacation with husband, Justin Timberlake, showing off her slim figure in black bikini bottoms and a cropped black shirt.

The new parents are on vacation in the Bahamas with friends. Presumably, the couple’s child is there on holiday with them as well.

Biel works with Walsh two to three times a week, and they do a lot of circuit and strength training—especially for her back and legs—which she says are quite weak from years of doing gymnastics when she was younger.

Biel told Elle magazine in an interview that “getting enough sleep, drinking lots of water, having a healthy diet, and staying away from alcohol are musts. It’s so boring, I know, but doing those things really helps.” One of the actress’ favorite restaurants is Real Food Daily because of the organic vegan cuisine it serves. But she does a lot of cooking at home herself with vegetables and grains.
