It's not too late to work on your summertime bod.  BTS has a series of FREE workout tutorials on YouTube posted through their record company Hybe.

They're releasing multiple videos as part of a 5-day challenge for a balanced body and mind. 

Each "Workout with BTS" video will be released weekly on Mondays…

Unfortunately, the seven members are not demonstrating the exercises, but there are clips of them throughout the videos. 

The exercises are led by a female instructor with an English voiceover. So far they've focused on the lower body, upper body, and then yesterday's was all about the core so you can get some rock hard abs.
