T-ara's Hyomin is working hard to tone up for the summer.

On July 12th, Hyomin shared the series of photos above via her official Twitter page and wrote, "This summer, I will do some exercise ball workouts."

Fans were immediately drawn to how small Hyomin's petite frame looked next to her exercise ball, and how fashionable she managed to be during her workouts.

"She looks so pretty, even when working out," they wrote, in addition to, "No wonder she's in such good shape," and more.

In related news, Hyomin and the rest of her T-ara members are actively promoting their new song "Day By Day".
