4minute posted a photo of their members hanging on poles upside down during practice, prompting more than a few laughs among online communities.

On May 1, 4minute's Sohyun tweeted, "4minute's boot camp. Why are we doing this? If you look closely, all five of us are in the picture," along with the photo of their peculiar contest.

In the photo are indeed all five members of 4minute, some hanging on to their dear lives with their legs crossed onto the practice pole, others barely making it into the photo. Decked out in camouflaged military pants, the members of 4minute seem to be enjoying themselves in between busy training sessions.

Internet users have responded, "No time to get bored, I bet" "Funny girls. Must be fun to be around them."

4minute has just made their comeback with "What's Your Name?" which steadily making its way to the top of various K-pop charts.
