AOA's Seolhyun revealed her trick to maintaining her great figure on the April 29 installment of 'Laws of the Jungle in Tonga'!

While she was exploring with Byung Man Jok to find fruits, Seolhyun discovered watermelon.  Holding it, she started to do squats.  She revealed, "I always used to do squats frequently."  She then put down the watermelon and went into full-scale squats. Seeing this, Chansung complimented her with, "[The form] is perfect."
