As any dancer knows, mastering a routine involves not just talent but a tremendous amount of hard work. It's even more challenging when the goal is to make a complex dance routine appear effortless. While some K-Pop dances might seem simple at first glance, there are certain choreographies that are surprisingly demanding. Here are ten K-Pop routines that are much more challenging than they appear.

1) RIIZE "Siren": This choreography looks smooth and effortless, but it requires substantial core strength due to the rapid and fluid movements. It's a deceptive challenge that's sure to leave you gasping for water after just a few tries.

2) RIIZE "Get a Guitar": The leg move during the chorus may look simple, but it's notoriously difficult to master. This is evident from the numerous challenge videos where people struggle to replicate it accurately.

3) Apink "Dumhdurum": APINK's hand movements in "Dumhdurum" are deceptively complex, creating an optical illusion that's challenging to replicate. Don’t underestimate it just because it involves hand movements.

4) BTS "Boys With Luv": Executing a mid-air kick during a dance routine is no easy feat. It requires precise timing and coordination, so be cautious not to trip over your own feet while attempting it.

5) Red Velvet "Dumb Dumb": While girl group routines might seem less intense than those of male groups, "Dumb Dumb" is an exception. Its complexity might surprise you once you actually try to dance to it.

6) KARA "Mister": The iconic suspender move in "Mister" may look easy, but it's a real test of hip flexibility. Give it a try, and you might discover how inflexible your hips are.

7) INFINITE "Before the Dawn": Known for their sharp choreography, INFINITE's scorpion dance in this song is incredibly demanding, especially if you lack core strength.

8) ITZY "WANNABE": Park Myung Soo's struggle with the shoulder dance move is proof of ITZY's meticulous effort to make this dance look flawless. It’s tougher than it seems!

9) SHINee Taemin "Move": The smooth and suave hip movements in "Move" are far more challenging to execute than they appear, requiring precision and control.

10) Jessi "Gum": This dance might have spawned countless challenges, but the behind-the-scenes footage reveals just how much even male idols struggle with the choreography.

Each of these routines showcases the incredible talent and hard work K-Pop artists put into their performances, proving that what looks easy on stage is often a result of endless practice and dedication.
