Fat or fit: a motto for a generation is a decent starting point for personal fitness philosophy. Fortunately-unfortunately, fitness involves exercise. Exercise needs guidance. Guidance is like gold dust, as scarce as hen's teeth. Random, non-specific aches and pains are routine but it's the acute or persistent knee complaints I worry about. Most people tend to take their knees for granted. Bear in mind, a painful knee (treated or not) grows older earlier than a normal one!

Whether you are a seasoned athlete, a weekend warrior, or totally laid-back when it comes to exercise, knowing how to protect your knees can mean the difference between a fulfilling lifestyle and long term, strained mobility.
