Girls' Generation Taeyeon showed off her abs.

On Feb. 15, Taeyeon revealed herself after exercising. Wearing a cropped top and leggings, Taeyeon showed off her figure with a straight body that stretched out against the wall.

In particular, she is a skinny body with a handful of waist, but clearly visible abdominal muscles boast an unexpected appearance. In addition, Taeyeon's ability to completely stand on her hands without leaning against the wall evokes admiration.

Taeyeon's secret to her muscles is known for her steady exercise. Taeyeon, who appeared on JTBC's "Petkage" in the past, showed her morning routine of  at home training.

Meanwhile, Taeyeon debuted as Girls' Generation in 2007 and is currently appearing on tvN's Amazing Saturday.
