This may be bias I have never tested Crossfit, so my opinions are derived strictly from observation and subjective perception. There is no doubt that Crossfit is metabolic costly. The workouts that I have seen implement dynamic, compound movements, coupled with large numbers of repetitions. Outside of being a intense calorie burn, and reported “fun” I believe the positives end there.
Risks and flaws associated with CrossFit that I have noticed.
1. There is a lack of care/concern for form.
-Many of the exercises performed with no attention to proper form. A large emphasis is placed on completed the workout.
2. Cookie cutter approach to fitness
-Whether you old, sedentary, athlete, or kid you perform the structured program with just minor variation.
3. Does not attain a goal and does everything haphazardly
-Strength, Power, Burn Fat, Hypertrophy, Endurance, Agility = Crossfit claims it does it all – Still figuring out HOW>>>?
4. Rhabdomyolysis – Breakdown of skeletal muscle (largely reported in Crossfit)
-Too Much, Too Fast, Too Soon
5. Group Setting
-There are so many issues that arise in a group setting that cannot be overcome unless in a one-on-one.
-I hate the word “functional” as it is very ambiguous. Anyway, the activities associated with crossfit are largely not representative of ANY daily activity. Therefore, specificity is a concern with the ability for your training to translate to daily life/sport.
7. Musculoskeletal Impairments
-This stems from the lack of form and the advanced exercises undertaken. Lack of concern is payed to the mechanical system and more on physiological leaving this area of potential concern.
I consider Crossfit the “Fad Diet” of Exercise. Crossfit will certainly burn extreme amounts of calories – buts its effectiveness long-term (adherence) is unlikely. Therefore, Crossfit as weight loss solution is doubtful in the long term (Will be testing this theory next spring). I believe results can be accomplished through more effective and efficient means through a structured periodized exercise program coupled with proper nutritional strategies.
Sorry for spilling the hate – but these are my opinions – Feel free to critique and disagree…the only way I better myself is being challenged ; )
