Here’s a quick (2 min) video from BTB CrossFit that shows what it’s all about
The video interprets a lot, but I’d like to add a few things in text form. In essence, CrossFit is a functional fitness program that prepares you for anything life can throw at you. My personal experience has found that CrossFit has done a much better job in preparing me for doing mundane things like yard-work, building fences, swinging a pick axe, etc.
I’ve been working out my entire life in just about all forms, going to the globo-gym, running races, wrestling, Ironman, etc. So far, I’ve found that CrossFit has enabled me to continue those athletic pursuits, set some new personal records, and feel better in daily life activities.
