I remember seeing a scene about this movie on youtube. I only remember one scene. A man punching sand in his own little apartment. It was either in a bowl or a bucket. He also used an oven for some reason either to heat up his fists or heat up the sand before punching it(to strengthen his fists). That being said that actor was ripped but skinny. All i remember. I cant find the same scene after an hour of searching and it bothers the ever living fuck outa me so im asking the internet for help lol
