Remember that ice skating is fun. Enjoy your time at the rink. Smile and laugh.
The great thing about learning how to ice skate is that you can do it at almost any age. Ice skating gives you a good aerobic workout and can improve your balance and coordination. Over time, you'll also strengthen your leg muscles, improve your joint flexibility, and have more endurance.
Health benefits aside, ice skating is fun! You don't need anything except access to an ice rink and the willingness to try something new. Wear clothing that is warm and lightweight, and that allows freedom of movement. A helmet isn't required, but if you're afraid of falling, a hockey or snowboarding helmet can give you some added protection (and confidence).
