“The wearable designed for lasting progress.”
"Lasting progress" applies to literally every fitness wearable. The hero doesn't name the differentiator (no screen, 24/7 wear, recovery focus) that justifies a subscription-only model when competitors are buy-once.
“"The fitness tracker with no screen. Wear it for a year. Train smarter, not more."”
"No screen" is the most concrete differentiator — and the easiest to remember. "Wear it for a year" addresses the subscription anxiety. "Train smarter, not more" implies a coaching layer, which is exactly what WHOOP's analytics provide.
