Knäböj ger kraftigare armar?

[Forest]

Alla vet väl att knäböj med fri stång är en kanonövning, här är en kul text på engelska som ger lite ytterligare inspiration:


When you suspend a weight over the entire body, that it's unaccustomed to, it brings more of the bodies 600 plus muscles into play. They fire on and off like crazy, acting as stabilizers through the assent and descent to keep you from toppling over. This makes a wave of stress hormones wash through the system and that's what stimulates the tremendous Growth Hormone release. No other exercise involves so many muscles, or stimulates anywhere near as much GH release as the free squat. That's why it truly is "The King of Exercises".
