Ben Sim — Performance Coach & Endurance Athlete
Ben Sim is a Malaysian performance coach and endurance athlete based in Petaling Jaya, Selangor. Working in the fitness industry since 2002, his experience spans personal training, group fitness, strength and conditioning, movement development, endurance performance and hybrid-race preparation.
His coaching combines structured progression with first-hand racing experience across 70.3 triathlon, Olympic-distance triathlon, duathlon and HYROX competition. Rather than separating strength and endurance into different worlds, Ben's approach develops the physical qualities athletes need to perform efficiently and confidently under fatigue.
How Ben Coaches.
Every programme starts with the athlete in front of him: their training history, current ability, movement quality, lifestyle, event demands and performance goals. Training is progressive rather than random, specific rather than excessive, and designed to develop performance that transfers beyond the gym.
