4Minute's HyunA has once again caused fans to become jealous of her sexy, slim figure.

On March 10th, the singer wrote on her Twitter "After practice ended, eu-huh-eu-huh (heavy breathing sound when exercising)", and attached a photo of herself running on the treadmill.

The singer showed fans that fashion doesn't need to be sacrificed even while exercising as she dons a loose whit wearing a loose boat neck tee, shorts, and pink sneakers that emphasize her slim shapely legs.

Fans responded, "You're exercising at this hour?", "Your legs are so pretty", "I can't see your face. Who are you?", "You must be exhausted", and "Don't go on a diet!"
