What are the basline principles of CF?
BTW, I saw your profile on the crossfit site. Nice lifts.
Thanks Barut.
Variety: this can be as simple or complicated as you want. Different shoes (or no shoes), different bar, different environment, altitude, temperature, humidity, pre-workout meal, time of day, sleep/rest/previous workout, sequence, exercise choice, weight used, % of max, total volume, etc.
Functional: this is NOT the bosu ball/wobble board bullshit that you hear about. Think movement patterns: squat, deadlift, climbling, jumping, pressing/pushing, pulling, cleans, etc. This list can also be modified to suit your sport, although I generally feel that strength work should be separate from skill work.
Intensity: an oversimplified translation would be "power output" at various time frames. How much power can you produce in less than 5 seconds (think vertical jump, max effort squat, max effort clean, snatch, whatever). How much power can you produce in 3 minutes? 5 minutes? 30 minutes?
Combine these three principles in a way that
1) addresses your weak links
2) is measurable
3) is progressive
I know that CF has been slammed for not doing the above, but a freely posted WOD is not a replacement for self-education and/or seeking out a good coach. I can tell you that there are tremendous athletes who do nothing more than the WOD, but there are also athletes who tweak and modify ... yet still follow the three basic principles.
As for safety, there are two ways to look at this. First, no successful program will be injury free. If you want injury free your intensity will be so low as to not produce a response in adaption (which will eventually result in injuries because the individual is a pussy). Show me a training program or sport that hasn't experienced some type of injury. Second, despite the claims of "high injury rates" from people who have never used it, CF has been independently tested by numerous military, police, and fire departments and proven to be safer than existing programs. I know that studies are never perfect, but it gives you some measurable results to help in the decision process. Obviously you will have to weigh pros and cons and see if the benefit is worth the risk.
Regarding the "same workout for everyone" bit ... I hope it is obvious that workouts are modified to the individual's level. Most people have enough common sense to scale back when something is posted that they simply can't do. I don't know many females who would complete 45 reps of 225 deadlift and handstand pushups, but I know quite a few who can complete 45 reps of 95 pound deadlifts and pushups. (This is just an example)
You wouldn't expect a beginner to walk into the gym and deadlift 600 pounds on first try.
You wouldn't expect a beginner to walk into a world class BJJ academy and wipe the floor with a BB.
And you wouldn't expect a beginner to tackle the WOD as written.
Scale to your level and gradually build up - just like anything else.
