4 ski trips, two are already booked, one in December, and one in February. Need one for March and hope to ski Chile in the summer of '18 but Chile is a long shot.
I am already working on the fitness part, I do 2 minutes 30 seconds of planks everyday, 2 minutes of wall squats everyday and I have another 4 minute exercise I don't really know how to describe that works on quad strength, and weight forward/inside edge at the same time. Oh yeah, I walk 6-10 miles a day way too often (work related).
I hope to go from a low level 4 newbie to being able to ski most if not all Blue runs (lets say less than 24* max gradient) by mid-February.
Edited to add:
It is nearly July, I would not wait too long to start getting in shape, it will be a new season before you know it.
