The 18‑year‑old eldest grandchild of Donald Trump posted a YouTube workout showing heavy lifting and cardio. Kai said she’s down to about 13 percent body fat — noting she normally averages roughly 15 — and flexed as she worked through lat pulldowns and weighted squats with her trainer.
Despite recent wrist surgery, Kai powered through standing squats loaded to 125 pounds, surprised that the bar weighed more than she does. She admitted upper‑body progress suffered while she’s done “no arms” work since November 2025, but praised her strong legs.
