These classes are hard and fun. However, based only on feedback from a client of mine who wrecked her posture doing Cross fit classes, and having personally attended similar classes: these type of classes need better supervision of participants, when they are either not aware their exercise form and alignment may be off or a particular exercise may not be suitable for them for whatever reason. Also these classes do not seem to stretch participants enough after a really hard class, which can also do harm to participants short of time or not “in tune” enough with their bodies, who may run off without stretching.
If these issues can be addressed I’m sure the class is suitable for most participants able and willing to do a great and hard class.
We must never underestimate the importance of personal attention and proper/sufficient stretching.
Obviously the business model was designed for the general population not for the well being of the new beginning exerciser.
I think that since we have no real regulations on who can do what, we can’t fault Cross Fit for figuring out a great money making plan.
I wouldn’t recommend Cross Fit to a beginner but that’s because I am a personal trainer and bootcamp instructor not a one size fits all fitness business.
