Great article by Ironman Coach Mike Bridge on how to tell good advice from bad. The bottom line is that very few fitness miracles have been unearthed recently. Time-tested principles, such as having a training plan, knowing your limits, building on your strengths and working on your weaknesses, and changing when it’s obvious you need to do so, are just a few that come to mind. Read this piece for more.

Perhaps the most pervasive and stubborn example of all this is stretching. It has been shown time and again to have no performance or injury prevention benefits, and it’s not even clear if it’s possible to stretch some muscles. But it is still touted everywhere as a cure, performance enhancer and general prerequisite for athletes. (Stretching still may have merit—the failure of science to prove something is not proof that something is invalid. Just be wary of trends.)In summary, if you read of some miraculous new training intervention in an off-the-shelf fitness magazine, online forum, or blog, I encourage you to be skeptical. Look for the scientific evidence that underpins it and decide for yourself just how miraculous it is.
