When it comes to the bar hangs for beginners, especially for people who can't necessarily hold themselves up, the thing I like to do with them is I like them to hang from a bar, but also to have their feet lightly touching a surface just to make sure that they are giving themselves enough grip onto the bar where it's challenging enough, but not to the point where they can't grip the bar at all.
初心者にバーハングをする場合、特に自分で体を支えることができない人にやってもらいたいのは、バーにぶら下がるだけでなく、足が軽く面に触れるようにして、バーへのグリップが十分かどうかを確認することだ。
