Kate Middleton's CrossFit habit and Prince William's past flirt with Isabella Calthorpe

Kate Middleton, 44, the wife of Prince William and mother of three, has been seen publicly at events such as Royal Ascot. She regularly practices CrossFit, training at Kensington Palace and the Harbour Club in Chelsea, citing the sport’s mix of cardio, strength and endurance as beneficial for both her physical fitness and mental well‑being.

Prince William, also 44, briefly dated socialite Isabella Calthorpe after a short separation from Kate in 2004. The relationship was introduced by his cousin Princess Eugenie but ended when William reconciled with Kate and later married her. Isabella later married Sam Branson, the son of billionaire Richard Branson.
