Functional training along with core/stability training are common buzz words in the personal training/fitness industry. Regrettably, like many things in this industry (do I sound jaded?), it sounds good but how it is usually applied is silly. Additionally, there is a lack of quality evidence for much of what is said regarding these aspects of training. I am not going to dive into the research at this time. However, I do strongly encourage any trainer or exercise professional to read the research (see below for my recommended readings) before you have people perform circus tricks. My main point is that for the majority of people who want to look and feel better (most people really want the looking better part, which usually means losing a good amount of fat, and will take the feeling better part if it comes along with the first part), there is no physiological need to stand on a BOSU ball or any other unstable surface in order to lose fat and/or function better in daily life. For a nice short piece on the subject click here.

What spurred me to write this short post is the following video that Matt had found recently. We found it very amusing. I thought I would pass it along.

Papers I found interesting regarding functional/core/stability stuff:
