clean and jerk 255kg

@mattiecakesssss (81kg, USA 🇺🇸) doing a no-no-no-yes clean and jerk with 143kg/315lb to set a new PR and American record, all while being really light at 78.6kg! This also set a 255kg AR in the total, about one month out from the Tokyo Olympics! She is a medal contender in the 87s — although she will likely have to increase her total a bit more as several lifters are in the 255-260 range in her class.
