It’s a very good idea to do some training before you come. We recommend you do a mix of cardio and core training before you start skiing or snowboarding with us.
A regular workout for your core muscles, lower body and basic stretching will help you a lot. Whistler’s on-piste and off-piste runs are quite long. It’s also good to skiing or snowboarding for a day or two before you come to Whistler (or on your first Sunday here) to get your muscles ready.
