Wevers was born on 17 September 1991, in Leeuwarden. She is six minutes younger than her fraternal twin, Sanne, who is an Olympic gold medalist. They are both members of the Dutch national gymnastics team and are coached by their father, Vincent Wevers. In 1992, Wevers and her family moved to Oldenzaal. When she was 12, she and her sister started training with their father at a local club in Dronrijp. The family later moved to Twente, and the twins started training at Top Gymnastics Eastern Netherlands. Her parents helped turn it into a high-level sports facility called BosanTON. In 2013, Vincent Wevers had an argument with the management of the facility and was fired. Ultimately, the twins moved with their father to Heerenveen to train, while their mother stayed in Oldenzaal. Lieke studies psychology and speaks Dutch, English, German, and French.
