Ramona Singer In Workout Gear Enjoys "Stunning Day In Southampton"

The Real Housewives of New York star Ramona Singer is enjoying the summer season at her house in the Hamptons. Singer, 67, shared a picture of herself wearing lilac tennis gear, posing next to a young instructor, her lush green yard in the background. "A stunning day in Southampton!!! Love rolling out of bed to have a tennis lesson on my court 🎾🎾🎾🎾," she captioned the post. Singer may be off RHONY but she is still keeping busy—here's how the reality star stays fit and healthy.

Singer enjoys plenty of protein in her diet and is mindful of portion sizes. "[Breakfast is] steel cut oatmeal, blueberries, strawberries (I love berries!), scrambled eggs or egg whites (sometimes I add in spinach or tomatoes to get in an extra serving of veggies!) and pair with whole grain toast," she writes on her website. "When dining out, I like to split the main entrée with a friend (restaurant portion sizes are typically double what you should be eating) and then get a side salad full of lots of veggies."

Singer uses the expertise of professionals for her health and wellness. "I felt it was important to hire a trainer; dieting can only do so much," she told Allure. "I do like to eat, and sometimes I eat the wrong things. Sometimes I work out five times a week, sometimes once, sometimes not at all."

Singer ups her cardio when she wants to burn more calories. "If I am ever looking to lose a little weight in a short amount of time I will cut out all bread and increase my cardio during workouts," she writes on her website. "I love core training as my main form of exercise, I love using kettlebells and bocce balls, as well as alternating planks. I typically do cardio on my core training off days, about 1-2 miles on the treadmill is great for me!"

Singer has switched up her workouts to focus more on strength-building. "As I got older, I started getting into free weights," she told Allure. "I always look up to women who are older who look great. Jane Fonda was alway my inspiration for my body. She was one of the first ones who used weights. So once I turned 30, I started lifting weights, and I stopped doing as much aerobic exercise."

Singer shares her favorite workout on her website:

3 sets of 20 reps

• Reverse lunge and press with 10 pound kettlebell weight
• Triceps push downs with 30 lbs
• Use a 20 lb kettle bell swinging 20 times each arm (do 20 reps)
• V's with arms and legs on a mat with 15-30 lb bar weight
• Planking on bosu ball with feet on the ball so they are raised off the floor for one minute
