Heather Rae El Moussa is stepping into the summer with confidence.

The "Selling Sunset" star and HGTV personality gave fans a glimpse into her wellness routine as she proudly showed off her bikini body.

In an exclusive interview with Fox News Digital, the 37-year-old opened up about the transformation of her mindset and body after welcoming her son, Tristan, with husband Tarek El Moussa.

"Well, I’m vegan. I’ve been vegan since I was in my 20s. So I eat very clean," El Moussa shared. "I think that’s a big part of it."

The new mom revealed that it had taken time to find her rhythm again after giving birth.

"After Tristan, it took me a little bit to get back into my workout routine, having a newborn and figuring out the balance of that," she explained. "I would walk a lot. And then I met my trainer, Paulina, and she started coming to my house. We would do workout routines at home. We added in weights."

For the reality star, weight training was a game-changer.

"I was never a weights girl," she admitted. "I was always like Pilates or running and cardio… I restricted carbs… I was really strict with what I ate. And after I started lifting weights and after I had Tristan, I really just needed — I wanted — to nourish my body… I just needed calories. I wanted healthy calories… I wanted to feel strong and empowered."
