Zucchini adores her dogs, and loves to walk them on the beach. Having a pet that keeps you active is ideal, experts say. "There's something very appealing about spending time with a dog who is so delighted to see you, and getting in an easy 4,500 steps before 10 am," says East Carolina University professor Melanie Sartore-Baldwin, PhD.

Zucchini loves to swim, which is not only fun but a great way to exercise. "Every time I go for a swim I feel like the earth and my incredible swim colleagues have enabled me to have experienced something pretty amazing," says Dr Jenny Martin, a physician and clinical pharmacologist at the University of Newcastle. "You get a release of hormones that make you feel good, like the molecules that are in morphine drugs, and other feel-good hormones like serotonin, dopaman swim in winter, you sometimes get a temporary natural high when you get out … definitely a euphoric feeling."

Zucchini enjoys fresh, delicious, coconut water for a hydrating treat. "Coconut water is abundant in several electrolytes including potassium, sodium and magnesium," says Stefani Sassos, MS, RDN, CSO, CDN, NASM-CPT. "If you're working up a sweat, especially in the summer months, coconut water may prove to be very useful."

No keto diet for Zucchini—she loves eating potatoes. "As well as being a good source of fiber, some of the starch in potatoes is particularly beneficial for our gut microbes," says registered nutritionist Kerry Torrens. "This is because it is 'resistant starch', meaning it's resistant to our digestion but can be broken down by our gut bacteria, providing them with the fuel they need to function and thrive. When we cook and cool potatoes, the starch granules lock together, making them more resistant to digestion. Studies suggest that when we include foods rich in resistant starch, we experience a host of health benefits, including more efficient digestion, less risk of some chronic diseases and a reduced risk of colon cancer."

Zucchini enjoys paddle boarding. "Our modern day lives have become largely disconnected from nature, with concrete and vehicles physically separating us from the outdoors, and what we value being far removed from what our brains developed to value," says paddle boarder and Dryrobe brand ambassador, Cal Major. "Stand-up paddle boarding can help counteract that. Gliding along the water, making little noise and travelling slowly allows for a peaceful immersion into the natural world around us."
