From Nov 1 to Jan 15 I start weight lifting and cross country skiing. From Jan 15 to Feb 15 I am back on the bike again 10-15 hours a week, and starting Feb 15, I start interval work. As long as you are excited about skiing and do not over do it each time out. I would recommend 2-4 rides a week even when you are skiing and lifting. For your weight workouts, emphasize your lower body and build power with fewer reps.
Proper technique is critical in lifting.
I would seek out a trainer or experienced friend to lift with. Report on Steve's first triathlon. Schedule - see whats coming up next on the calendar. Tools of the Trade - check out Steve's 2001 machine.
