It's important to warm up because that allows your body time to adjust to the physiological demands of the sport. Take a couple of minutes before each run to stretch out and loosen your muscles. Remember, while you've been on that chairlift, your muscles have probably cooled and tightened. The run phase is the part where you just relax and enjoy the physical exertion and the terrain of the run. It's also important to cool down because that allows your body to reset and prepare for recovery.
Proper hydration is also critical to performing well and staying safe.
Since the body is more than 70 percent water, it's crucial to replace what you expend. Skiing often takes place at high altitudes where it's easy to get dehydrated. So when you're bouncing over moguls, make sure you drink plenty of water at regular intervals during the day. Dehydration can lead to muscle cramps, heat stroke, premature fatigue or even muscle injury. Keep it saturated.
