Rocking just her nude undies, the 38-year-old has all the focus on her flawless butt!
Her body is insane!! Can you even believe she’s had six kids??
If her derriere isn’t enough proof, the reality TV starlet also shared another fit snap to IG earlier this week (below):

4 miles tonight I ran!! It wasn’t until I had to do a stress test back In May that I felt comfortable running again since the device was put in my heart. Little did I know that stress test would heal (as much as it could) the fear I had of exerting myself (my heart rate) my cardiologist stood there (my medical team at Emory are the best) so there I was walking, then slow running, then running and I figured wellllll shit if I’m going to drop dead my cardiologist is right here what do I have to lose ├░┼╕╦£┼ô since that day I have slowly built myself up to running pretty consistently without stopping! I ALWAYS knew something was wrong w/ my heart my friends could go and go and I always had to stop for breaks (even back in Elementary school) I just feel so grateful to be able to continuously run! I’m so thankful for my girls who drove the golf cart behind me from the beginning just in case I had a problem! I love them so much! Heart health is so important (mine was genetic) GET YOUR ASS UP AND LETS GO YOU GUYS NEW YEAR NEW YOU! You have to start somewhere!!!A photo posted by Kim Zolciak-Biermann (@kimzolciakbiermann) on Jan 2, 2017 at 6:39pm PST
