I was watching some old fight clips and one of them was the Fedor Emelianenko vs Gary Goodridge fight. During the pounding of Goodridge, I noticed that Fedor hits with the insides of his fist, the side with the thumb when he throws his hooks. Is this a (commonly) practiced technique or is it chalked up to Fedor's natural fighting style? Has anyone tried this out? I'd give it a shot myself but just had surgery done on my wrist.
