Teen Mom alum Mackenzie McKee wowed fans with her incredible fitness transformation just two months after welcoming twins with husband Khesanio Hall. The reality star, 30, put her toned post-baby body on display in gym gear, rocking a gray crop top and matching shorts in a video posted to her TikTok on Tuesday, August 26. While showcasing her postpartum figure, McKee could be seen doing jumps on a trampoline before launching into a front flip. One day prior, McKee posted another workout video during her exercise session with Hall, 30, that she also shared via Instagram.
