Lucciana Beynon in Bathing Suit Prepares for "Next Show"

Model Lucciana Beynon is getting ready to celebrate her birthday—but work comes first for the daughter of Travers Beynon and Ninibeth Leal. Beynon, who turns 22 on July 9, shared a picture of herself posing backstage in a makeup chair, wearing a black and gold one-piece bikini. "Next show," she wrote on her selfie. How does she stay so fit? Read on to see 5 ways Beynon stays in shape and the photos that prove they work.

Beynon loves boxing workouts with a personal trainer at the gym. "Boxing is an excellent way to improve your cardiovascular endurance," says the American Sports & Fitness Association. "During a boxing workout, you will use your whole body to throw punches and execute combinations. As a result, your heart rate will be elevated for the duration of the workout. Not only that, but due to the intensity of the workout, you'll burn more calories than other forms of exercise."

Beynon is a big fan of using the StairMaster machine for convenient cardio that's gentle on the joints. "Climbing stairs is one of the best ways to burn calories in a short amount of time," says Todd Buckingham, PhD. "Plus, the StairMaster is great for building your leg muscles, particularly your glutes, hamstrings and quads."

Beynon uses weights and dumbbells to build muscle and tone up. "You don't need to spend hours a day lifting weights to benefit from strength training. You can see significant improvement in your strength with just two or three 20- or 30-minute strength training sessions a week," says the Mayo Clinic. "As your muscle mass increases, you'll likely be able to lift weight more easily and for longer periods of time. If you keep it up, you can continue to increase your strength, even if you're not in shape when you begin."

Beynon's social media highlights just how much she enjoys dancing—which research shows has incredible health benefits. "For rhythmic dances, such as the foxtrot or waltz, a 160-pound person will burn an estimated 130 calories in 30 minutes," says Jessica Matthews, MS. "For more intense styles of dance such as the salsa, the number of calories burned doubles to approximately 250 calories in 30 minutes, which is comparable to performing a light jog for the same duration."

Beynon loves swimming outdoors, whether it's in the ocean or in a pool. "Research shows us that being in or next to water reduces our blood pressure, slows our breathing down and allows our parasympathetic nervous system to do its job," says Catherine Kelly, PhD. "This is our 'rest, repair and repose' system and is vital for effective brain function and a strong immune system. Water encourages us to relax, in other words."
