Go drag a sled a LOT an ok weighted one not to damn heavy butr drag that sucker go for a 30-60 min walk draging it up down hills etc. Or even a tire. Also a weighted vest. Go hiking.
sure keep up the leg work outs but he's right 2 weeks out yoiur fried if not in somewhaT GOOD SHAPE.
Id also suggest you do the last HARD leg workout at least 5 days out and go skiing fresh. Bedtter to be fresh and have a great time skiing then be broke down and have a shit time.
