Good models aren’t born, they’re trained, and working with Bel Ami means they’re trained by the best. Bel Ami’s “Personal Trainers,” Dano Sulik, Sebastian Bonnet and Marc Vidal, teach raw young recruits how to give and take it like men. Spontaneous and unrehearsed, the cinema vérité filming captures every second of the explosive action in the non-stop sex-a-thons. The ninth “Personal Trainers” video is a worthy addition to—what a prescient reviewer predicted very early on— “one of the great series of all time.”
