The weight itself might not be a problem
His technique or his breathing can hinder his training
The thing is, I feel like the weight, is light enough that technique shouldn't have a major factor?( I'm thinking technique would only help him another 30% , but no technique is not enough that he'd be struggling?) Especially since he was trained in Upper body strength from that sword..
Honestly, I'm a bit upset that he was shown to be struggling with the HANDLE of the weights, even though he had been training with a freakishly heavy looking wooden sword
