Chan is not your normal celebrity trainer. His vibe is almost monastic; the gym is zen. He exudes a confident serenity that engenders trust immediately – particularly useful when he hands over an 8kg weighted log, also known as a ViPR, and tells me to arabesque. There’s no sparkly Peloton enthusiasm; no intense Barry’s playlists; no military-style yelling beside the treadmill. “This isn’t some LA celebrity woo-woo bullshit,” he says. In the gym, the only branding is the word “Roydian” embroidered into face cloths and stamped across protein-shake cups. It’s also stickered in a tiny insignia on the window, which overlooks the Los Angeles sprawl.
