Jessica Biel showed off her sexy physique in Puerto Rico.

The “Summer Catch” cutie donned an O’Neill wetsuit and bikini bottom as she hopped into the Atlantic Ocean for a leisurely swim.

As for her secret to keeping a stellar body, Biel told press, "For me, 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."

"Yoga is a constant for me because it keeps my muscles long and flexible. But now that summer's coming around, I'm planning on spending more time outdoors playing volleyball and jogging with my dog, Tina."
