This is totally the best exercise!

If that area gets trained, there will be a problem...

The text "ㅋヲヲヲヲ" does not have a meaningful translation as it appears to be a combination of characters that do not form a coherent phrase. It seems to include Korean "ㅋ" (which represents laughter) and Japanese characters "ヲ" (which is a phonetic character). If you have more context or a different text, please provide it!
