I actually don't know how anyone could watch a Glassman video or interview or read one of his articles, and Castro, too. Especially Castro, and still take it seriously. I think the way "HQ" conduct themselves is a joke. Look at all the "guru's" they have hired and fired, and normally when said guru criticised any one little thing about their system. Mark Rippetoe and Rob Wolf are good examples. Both used to make me "want" to like it but I never could. Then they eventually had enough of the crap and left, subsequently got abuse from the cult, and subsequently hit back, which actually made me lose a little respect for them. Somewhere rip said he done CF for 4 years and is still trying to fix the damage it done. Really? The guy responsible for Starting Strength and Practical Programming - amazing resources - took 4 years to realise how nuts it was???
Lets face it, CF is just circuit training................. Circuit training has been around since forever. You can do it in an insane way, like CF, or a sensible way, like it's always been done. The beauty of circuit training is you can do it whatever way you want which means you can use exercises that won't be near impossible to maintain safe technique when fatigue kicks in, but still get the same training effect (which, in simple terms, is to get really out of breath).
There is actually an article somewhere I think by Dave Castro where they state "technique doesn't matter with high reps and lighter loads".
We've came along way in terms of learning how the body works to know this isn't the case. It just doesn't make sense, either. It basically blames load for injury, which flies in the face of the majority of, for example, lower back injuries, which involve picking up a pen or a newspaper, and not a maximum load.
Your body works off movement patterns which are enforced by "habit" and habit is enforced with repetition. Enforce an unsafe pattern and you will multiply the wear and tear, and also make yourself far more likely to fall into the unsafe pattern if you do try and lift anything heavy.
It's a short sighted approach from people who really should know better... and probably do know better.
As Kenny has quoted for years on this, "practice doesn't make perfect, perfect practice makes perfect".
Where I will give them credit is they're marketing geniuses. Out with teh safety side of it, the other main criticism was always, "jack of all trades, master of none". Their wild claims of CF being the best way to get strong, fit, explosive, lean, muscular, pretty much everything you would ever want from any kind of exercise all in one WOD. This was always nonesense.
Until the CF games. Ha. Changes everything. Now CF is "specific" - to the CF games!!! Brilliant. Obviously the best way to train for CF games is to do CF! On top of that they position the CF games as representative of "exercise" or "fitness" in general. So if you are competitive in the games you are competitive in the "sport" of exercise/fitness.
As someone with a marketing back ground, I will put my hand up and say they are without a doubt marketing geniuses. Credit where it's due!
