Q. What are your thoughts about plyometric training for young athletes?
A. If you ask any trainer this question you are bound to get varying responses from those that love plyometric training for all ages to those who think that it is way too advance for young athletes. I think that while some plyometric exercises may be a little challenging and inappropriate for children (i.e. Drop down box jumps from 3 feet), there are many that can enhance and improve body movement at a young age setting the stage for advanced development later in life.

Q. I am 42 years old and trying to delay total knee surgery as long as possible. I heard that glucosamine supplements help, is that true?
A. Glucosamine supplements have been around for a long time. Because of this, they are one of the most studied and reviewed non-prescription pills on the market. Even several prestigious orthopedic and medical journals have published some findings from controlled, double-blind, placebo studies. Most of these studies test the effectiveness of the supplement on knee cartilage density and, of course, reduction of painful symptoms.
