Myth: It's bad to continue building strength and power after the ski season starts.
"People used to think you should build all your strength in the off-season, then during the year you just had to maintain it and perform," says Stone, who served 11 years as a U.S. Ski Team physician. "But recently we've seen a lot of younger athletes getting better and better during the season-not only because of their experience but also because they're getting stronger." That doesn't mean anything goes, however. To avoid injury, spend a lot of time stretching and be careful not to overtrain.
Set for the Season: November/December
