Angela Simmons is already back in the gym — less than two weeks after giving birth to her first child last month. 

The Growing Up Hip Hop star, 29, posted an Instagram photo of herself in the gym wearing black leggings and a neon-color zip-up jacket on Wednesday, October 5, with the caption: “Light workouts approved by the DOC ✔️ #13DaysPostBaby #Day1Gym 🙌💪.”

Simmons, who is the daughter of Rev. Run of influential hip-hop group Run-DMC, announced the arrival of her son via Instagram on September 29.

“The best part of life has just begun ❤️🙏👶💍 #Motherhood #ImSoInLove,” the reality star — who has also appeared on Run’s House, Daddy’s Girls and Rev Run’s Sunday Suppers — captioned a sweet photo of herself holding her newborn in bed. 

Simmons, who is engaged to Atlanta businessman Sutton Tennyson, also announced their engagement via Instagram, sharing sparkly footage of her ring this past April.

“YES!! I couldn't be more excited. This is only something I could of only dreamed of. I'm over the moon and feeling so blessed to be able to share my life with the one I truly love. Everything happened in the most perfect way. 💍💍😍😍❤️❤️,” she wrote alongside the clip of her new bling.

Simmons has yet to announce her baby’s name.
