"Ahhhhh we love you, Noah!" wrote Robin Arzón, while Jess Sims added, "OMG YOUR TWINNNNN!!! Hi baby Noah!!! Cannot wait to meet you and kiss your cheeks off!!!"

"Congrats on a beautiful baby boy Mamma‼️‼️❤️❤️," replied Alex Toussaint.

Dr. Chelsea Roberts Jackson, who is currently expecting her first baby, added, "Welcome to the world Sweet Noah ❤️"

Greenberg first revealed the exciting news of her pregnancy during one of her live yoga classes and later shared the announcement on Instagram in March.

"Loki & Mia 🐕🐕 get a 👶🏼 (human) sibling this August & we all could not be more excited to meet them 🥰🎉🎉," she captioned the video montage, which featured photos of her baby bump and sonograms of her little one on the way.

"ANNA!!! This video! Cryinggg. We love you, bb," wrote Arzón while Jess King added, "Squueeaaal! Love you and the bump!!!"

Greenberg has been teaching at Peloton for three years. Throughout her pregnancy, she has released a collection of prenatal classes for each trimester.

"It's been so special creating these classes, sharing my experiences, & knowing that I'll be joining others as they go through their own," she said of the workouts in an Instagram post.

"Feeling connected to other people who have gone through or are going through their own pregnancy journeys has been so important to my physical & mental well-being. There are so many incredible, wonderful things about this time, but it can also be scary & a lot to take on alone."

"I hope these classes provide a safe space for other pregnant people to feel connected & know that even though each of our experiences is unique, we are not alone! Always feel free to reach out to me & let me know how it's going, ask questions or just say hi ❤️ we are in this together 🙏🏼"
