K-pop boy group iKON's BOBBY talked about the difference in his physical strength.

On October 16, iKON's BOBBY and Donghyuk sent greetings to their fans via Naver's V Live. 

BOBBY said, "My health condition is different when I was 20 and 23 years old." 
Then he explained, "Since we have to use our body a lot, it is tiring. But we still have bright future ahead of us." 

BOBBY continued, "Before, doing two shows in one day was very easy, but now, near the end of the concert my legs are trembling." 

Then Donghyuk and BOBBY agreed, "I really respect BIGBANG bros."
