I really need to strengthen my knees which kill while skiing. I have an exercising ball , some weights, and a treadmill.

Lets say your in relatively good shape but you want to boost your exercises up a notch to prepare it for an intense ski trip. What type of cardiovascular/ weight exercises should you do to prepare your body and especially the muscles you use to turn you body and to make ski jumps, paying particular attention to the muscles you use to ski so that you don’t feel pain after skiing from not using those muscles.

I’m going on a two day skiing trip in a week. I haven’t been skiing in years and do remember it was pretty physically demanding. I am in pretty good shape, work out probably 4-5 days a week, but is there anything I can specifically do to prepare for the trip? Certain muscles or exercises?

I like skiing, but the season is almost over and I am getting ready for the soccer (football) season. How much does skiing help (if at all) for soccer?

How many calories can you burn?
What major muscle groups are you using?
Is it low or high impact? (Maybe that depends on falling.)

For an intermediate to advanced skiing.

I went on the school skiing trip last year and did loads of workouts for that but I read somewhere that actually a lot of "skiing exercises" don’t actually do anything to help you when skiing. Does anyone know any exercises/stretches, etc. that will help prepare me for skiing again (not anything to do with exercise machines please (I don’t have any))
