Aimee Fuller was born in England but now lives in the USA. She moved to the east coast of the United States at the age of 12 because she knew she wanted to be a professional snowboarder. It wasn’t possible to train properly in her hometown because it hardly ever snowed. There was a dry ski slope in her town, where she learnt how to ski and snowboard, but there weren’t any mountains with snow to practice the sport. Aimee quickly found sponsors and a coach when she arrived in the USA, and she is now a successful and well-known snowboarding star. She has done really well in many national competitions and her dream is to win an Olympic gold medal one day.
During her free time, Aimee likes to spend time at home, switch off her phone and laptop and hang out with her friends and family. Aimee spends most of her time practicing on the snow, and trains in the gym four to five times a week. She also goes cycling and running. Aimee says it is very important to keep fit because that helps her stay safe when she is doing snowboarding tricks and jumps. Her advice to people who want to learn how to do jumps, is to start small and only do bigger jumps when they feel ready.
