Decided to do the Level 1 Crossfit certification and pleased to say I passed.
Too Easy to pass?
Obviously, Crossfit gets a lot of stick, some of that is justified. One of the main issues is that you can teach CrossFit classes after only getting through a 2-day course.
Being able to instruct highly technical moves such as the snatch or clean and jerk after a 2-day course is scary, but this is why it's so important that the Crossfit boxes take responsibility for who they hire.
When it comes to health and fitness I like to employ the wisdom of Bruce Lee
"Absorb what is useful, discard what is useless and add what is specifically your own".
As such I've taken some parts of CrossFit, such as endurance, Olympic lifting, gymnastics, agility and added these to my own training to make myself a better all-around athlete. Learning new moves constantly is damn fun and a good way to keep the motivation going. I would much prefer to burn some extra calories learning a new skill like a handstand or human flag as opposed to walking on a treadmill.
There's so much dogma out there and it's easy to dismiss something like CrossFit, but my best advice is to be open-minded enough to give it a go. It will quickly expose your weaknesses and give you the chance to improve in the process.
