I could go off for a while about functional training
Well, let me expound on "functional training." Here is an over used, misunderstood, hyped term in the general populas.
For them the term,"functional traiing" means performing some exercise on some type of unstable surface. That does not appear to be what you were talking about in your post.
Training on an unstabel surface is NOT very fuctional. Very few situstions in "functional" every day life will place the majority of indivuduals in this situation.
Only a few idiots would stand on a chair with wheels on it and change a light bulb. If you change light bulbs that way, then train on a chair with wheels on it. The "Law of Specificity" in training.
Also, "Unless you're training to be part of the circus...these foo-foo pieces of equipment have no place in a healthy individual's training program." Training Disasters by Tony Gentilcore http://www.t-nation.com/readArticle.do; ... id=1785278
Tudor Bompa stated at a NSCA National Conference, "Tudor said that balance training is only good for women's gymnastics, and even they don't use all this gimmicky equipment. Instead, they train for balance on the apparatus itself." http://www.t-nation.com/readArticle.do?id=462024
A squat is a functioonal exercise. It increased strength in the primary and stabilizer mucle groups. Thus, enabling one to sit and get up off the tolit, a chair or the sofa. Now that an important "fuctional" movement.
As Tim noted, Cross Fit has some great functional exericses...exercise that relate to what we all do in life.
Kettlebell programs are quite functional. The question is, "What don't they work?"
Also, Cross Fit and Kettlebell training is brutal. In discussing kettlebell training with someone once they told me the could have me puking in 10 minutes.
I replied, "I DON'T think so. It would only take 5 minutes."
