Farrah Abraham, 29, proved she still knows how to look good even when she works up a sweat! The Teen Mom OG star spent some time doing outside yoga in Palm Beach on Mar. 14 and wowed in a florescent pink thong one-piece that accentuated her figure. She posed in various stretching positions, including one in which she laid on her stomach and lifted the upper half of her body while her head was stretched back.
