About this time of year, well a few weeks ago, I do some leg exercises in anticipation of the season.
Go on the elliptical machine, set it to steep and do half an hour. Give yourself hell. Loud music will help. Then work out a little routine for your legs paying attention to your glutes ... get a 50/60 lb bar and put in 60 squats, go on the leg press, another 60 (120lb+ with your glutes and core tight), then do 60 rep with the hamstring and quad machine, do a bunch of reverse lunges (watch your knees, forward lunges are a pest for that), ten big deadlifts, some single leg romanians, some side lunges, some pliés and some side abductions for your hips, and the equivalent adduction. Do some pressups too, in 20s, for tightening up.
You likely won't walk the next day
I know I don't. But, if you can do that once every three days, by the third time you will have bulletproof and super strong legs. It'll affect your core too, especially if you can manage to do something light like a bit of a yoga or a swim in the off days. You'll notice your posture change and your time on the snow will be so much more fun. It'll have you standing upright on your skis ... which makes ALL the difference. It is medicine, but good medicine.
