Keep your body erect, your knees straight, and your hips forward. DO NOT bend at the waist. Make sure your heels remain on the ground. Alternate foot position by turning the feet outward, stretching, then inward, and repeating the stretch. Aerobic exercise should be done for 20-30 minutes at least 3 times a week.
Squats are a good exercise for the multiple muscle groups that are used during snowboarding.
Squats are performed from a standing position with feet shoulder width apart. The exercise begins by flexing the hips, knees and ankles until thighs are parallel to the floor. At that point, return to the standing position. Start with 3 sets of 10 repetitions and progress as appropriate. Calf strength is necessary in snowboarding for performing turns as well as maintaining overall balance while snowboarding.
