François Arnaud is taking his breakout year beyond television, with the Heated Rivalry star officially joining Under Armour as the sportswear giant's newest global brand ambassador.

The actor fronts Under Armour's latest HeatGear campaign, marking his first major fashion and fitness partnership since Heated Rivalry became one of the year's biggest television sensations. The campaign showcases Arnaud in the brand's signature performance apparel, celebrating strength, movement and athletic confidence.

Under Armour said Arnaud embodies the determination and resilience at the heart of the brand's identity, with the campaign highlighting its latest HeatGear collection designed for training in warm conditions.
