I think you should try it, and then decide. I have been doing Crossfit for about 2 years now. That it has improved my riding is beyond debate. I climb faster now than when I was logging huge mileage as a roadie. I am more comfortable in the air, and faster on the descent, because I am much stronger now. For me, it works, and I am definitely not type A.
That being said, every boxes differs, in programming philosophy and sophistication of coaches. Some of what is being said here is true, if you can't check your ego at the door, you will get hurt. Same deal if your coach is a meathead.
Nothing has ever improved my fitness as much as Crossfit, but I took it slow, and I scale workouts when I need to. 2 years in, I have no injuries, and no intention of developing any.
Forget about rhabdomyolysis, you are more likely to develop that from an 8 hour epic on the bike than a Crossfit workout.
Try it out. It's only exercise.
pretty good response.
i will add that almost any training program/routine can provide you with good benefits as it's not what you do but how you do it. the how you do it is all about techinque and loading where loading is a function of the intensity, volume and frequency of your workouts. people get hurt becuase of the how - poor tehcnique and over loading - not because of the what.
the key thing when choosing a training routine is to pick one that compliments the activities you enjoy and do the most. the reason for this is that you can't maximize all levels of physiological performance. anybody that says they can are either using a boatload of supplements, illegal drugs, both of those or are simply full of crap. you simply cannot train at a high level for strength and cardio at the same time, you'll last about 10-14 days at most before you start to fall apart. if you think you're doing both and surviving then you're not training at the high level that you think you are.
when is comes to human performance you can essentially do one of three things:
1. you can maximize strength, power, explosiveness, speed, agility and have low to moderate levels of cardio vascular performance
2. you can maximize cardio vascular performance and have low to moderate levels of strength, etc.
3. you can have moderate to good (but not great) levels of cardio and strength.
imo the way most people tend to ride (or play other sports) they should have more emphasis on strength/resistance training and less emphasis on cardio training. say anywhere from a 80/20 to 60/40 split. the reason being is that good to great leg strength will help carry you on climbs up to a couple of hours and make steeper climbs far easier compared to if you are focusing on cardio conditiong.
i also beleive that resistance training can provide you with more overall health benefits than cardio training. that's not to say one should ignore cardio training, but the avg person or rec athlete will get better health/performance benefits from focusing more on resistance training that cardio traing; about a 60/40 to 70/30 split.
so yes, go try the crossfit as you may like it and take it slow. once you get a taste for it and understand the principle then factor in your total activity level (incl your job) when deciding how much effort you want to put into it. if nothing else it will give you some great training ideas that you can inocorporate into a different training program.
one of the key values of a trainer or coach is helping you determine your loading and keeping it at a level that allows for performance growth without causing fatigue or injury.
We don't know what our limits are, so to start something with the idea of being limited actually ends up limiting us.
