A healthy lifestyle. Peta Murgatroyd may be 20 weeks pregnant, but she’s still doing her best to stay active and exercise every day.

The Dancing With the Stars pro, who is expecting her first child with fiancé Maksim Chmerkovskiy, took to Instagram on Friday, August 19, to discuss her gym routine.

“I am loving keeping fit whilst I’m pregnant,” Murgatroyd, 30, captioned a video of herself doing dumbbell and medicine ball exercises. “I’m 20 weeks and although I could sit on the couch and watch TV all day, I have to get up and keep moving! To me it’s imperative for women to have an active pregnancy. It’s better for your well being and it’s great for your baby (within the limits your doctor has given you of course).”

The pro dancer continued, “Everyone will have an opinion about this, and that’s ok, but until I’m too big that I can’t move, I will be doing some sort of exercise each day. Believe me, it’s not easy, I’m not used to this body I have at the moment, and I’m heavier than I have ever been.”

However, Murgatroyd says she and her hunky Ukrainian beau, 36, often share a laugh at her growing belly. “The parts @maksimc and I laugh about the most, are the fact that I have to roll out of bed (I don’t want to squish the baby), I use my hands to push myself off the couch and he has to boost my butt out of his low car. Ladies, your health is everything and we have to laugh.”

Us Weekly confirmed in May that the happy couple were expecting their first child. The pro dancers, who have been dating on and off for three years, got engaged in December 2015. Their firstborn, a baby boy, is due in January.
