FLEXIBLE GAME PLAN
Maybe the desire to stretch just isn't part of your DNA.
Don't despair, says Maureen Madden, a physical therapist at The Stone Clinic. "You don't need to be yogi-master flexible or ballerina flexible, because you don't do those things," she explains. "What you do need to do is maximize your own potential." To do so, follow these three guidelines:
Stretch muscles that feel tight (we guarantee that includes your hamstrings and hip flexors).
Identify the positions you need to be in to ski at your best, and make sure you're flexible enough to hold those positions.
Think symmetry. If corresponding body parts (say, right hamstring and left hamstring, or right hamstring and right quad) aren't equally flexible, you're a prime candidate for injury.
