Heavyweight somersault
What weight do you think this big guy squats with? It seems there is at least 150 kilograms, or even more. This does not include the neck itself. After approaching with such weight, many would feel dizzy. But this giant just did a backflip!
Well, you said heavyweights are awkward. Yes, this is a real ninja! The guy on the next machine couldn't contain his admiration.
