Heather Locklear is looking anything but 53 years old after celebrating her birthday on Thursday.
The Melrose Place alum celebrated by playing a few rounds of tennis in Calabasas, California, and she looked great wearing minimal makeup and a tight tank top and spandex pants.
The Spin City actress says she enjoys a variety of activities to stay fit.
"I do resistance training three times a week. That really helps with defying gravity and keeping things in place," the actress told Parade magazine in January. "I have light weights to do reps with both my arms and legs. I do cardio a couple times a week on the treadmill, with the music blasting. It's what gets me through."
Locklear said she is faithful to her workout routines, mostly because it's easier to keep it up than to start up again after time away.
"If I miss my workouts for a few weeks, it's harder when I go back," said Locklear. "Keeping up with the healthy lifestyle makes it easier in the long run."

She said exercise, "especially cardio," helps her keep a positive attitude.
"I also love to play golf and tennis," she said. "Even a walk in the evening can take the edge off a bad day," she said.
As to her diet, the actress says she keeps it simple and doesn't go overboard.
"I use portion control and try to keep it healthy 80 percent of the time. I don't deny myself carbs or sweets," said Locklear. "I just make every effort to keep it within reason."
Her favorite indulgence? Drive-thru restaurants.
"Sometimes when I'm tired after a long day's work it seems like the easy thing to do, but the next day I regret it," Locklear admitted.
Locklear told Parade that "good genes" help her maintain her youthful appearance, along with "taking care of what you've got: sunscreen, exercise, diet, water, and being happy and content."
