Petchtanong Petchfergus, a former ONE bantamweight kickboxing world champion from Bangkok, Thailand, is redefining his training approach by integrating modern sports science and medicine. At 40 years old, he still competes effectively against younger fighters. In a recent interview, he highlighted the critical role of recovery and nutrition in training, stating that traditional methods can lead to decreased speed and flexibility. Petchtanong has recently enjoyed success, winning three of his last five bouts. He is set to return to the ring this weekend at ONE Fight Night 43, where he will face British veteran Ben Woolliss in a three-round bantamweight kickboxing matchup. The fight will take place at Lumpinee Stadium in Bangkok, and the winner could potentially challenge for the bantamweight title currently held by Jonathan Haggerty.
