Former UFC welterweight champion Georges St-Pierre has hinted at a potential return to fighting by attending a six-week training camp to evaluate whether to continue fighting or retire. St-Pierre has been training in Brazilian Jiu-Jitsu, wrestling and boxing with coaches like Firas Zahabi, who believes St-Pierre still has more fighting left if he prepares properly. St-Pierre is considered one of the greatest MMA fighters ever and took up martial arts at age 16, becoming a black belt and finding success early in his UFC career.
