HGTV star Christina Haack is known for her petite figure and her Barbie-doll esque features. Her secret to them? Staying active, and actually enjoying it. "Exercise is my stress reliever," she said to People. "There is nothing like a good three-mile run for me to really clear my head and get my endorphins going."

Madison LeCroy escaped to the beach this week, and posted several bikini photos on her Instagram story. LeCroy told BravoTV.com that going into lockdown helped her adjust her diet and start to eat healthy again. "I just said, 'This has got to stop, so I'm gonna make these foods and I'm gonna eat this kale salad and eat grilled chicken and broccoli four days a week, or whatever it was, and no alcohol for 14 days.' That kind of thing was very tough." 

Kim Kardashian may have just gone Instagram official with her beau Pete Davidson, as the two might have taken a beach vacation together, and fans speculate he took her bathing suit photos for Instagram. Kardashian has been open about her wellness routine, and her struggles with her weight after having kids. Her newest wellness venture is adopting a plant-based diet. "I live a healthy life and try to eat as plant based as possible and drink sea moss smoothies," she says to Poosh. 

Singer Nicole Scherzinger is known for her incredible figure, and this week danced with her partner after taking an ice bath. She tells Cosmopolitan that she tries to stay as active as she can, and that she actually enjoys working out. "What really helps me is working out. Even if it's not for very long, [I love] to get a sweat on to keep me focused and positive."

Fashion maven and former pageant winner Olivia Culpo, who posed with NFL boyfriend Christian McCaffrey, tells HollywoodLife that her go-to workout class is SoulCycle. She says that it not only helps her stay in shape, but it helps with her mental health.  "I really do like SoulCycle. I just feel like it's an easy meditative way to work out. I can really zone out during that workout."

Singer and TV personality Rita Ora says that circuit training is the best way for her to stay active and stay in shape with her busy schedule. She tells Shape that she likes to focus on certain areas, and does a circuit for each one. "I do three circuits and repeat that three times. I mostly focus on my thighs and my bum, so I do a lot of squats and weight lifting. And I do one circuit of cardio." 

Former Real Housewife Bethenny Frankel posted a photo of herself in a while one-piece swimsuit on Instagram, as she wanted to show off the results of her "January cleanse." Prior to being a reality star, Frankel was known as a natural food chef, and she tells HollywoodLife that she keeps her diet as clean and as natural as possible. "I do not eat a lot of 'fake' foods. I'll eat cake and fries but nothing brightly colored or artificial."
