Safety Notes Always keep safety in mind! Never begin a vigorous exercise routine or engage in extreme sports without consulting with your doctor first. Always wear a helmet, and any other protective gear appropriate for your activity. Wrist guards are usually a good idea too. Make sure the area you choose is an appropriate surface, free and clear of any obstructions. Know your limtis and use good judgement. Don't attempt to do things you're not sure you can do. Don't practice extreme sports alone. Use the buddy system. Always wear a life preserver when doing anything in or near water.
