Traditional weightlifters and cross trainers don’t see eye to eye on training. However, the best approach to training isn’t as black & white as you may think.

Dr. Alex Jimenez D.C.,C.C.S.T’s insight:

Crossfit vs weight lifting, an argument can be made for both.  Crossfit programs build muscle and cardiorespiratory fitness at the same time without requiring hours of exercise on a treadmill or elliptical trainer. Many recent studies found that high-intensity training produced startlingly rapid results. The focus of crossfit includes full body motions.  In essence, you are working many joints at one time.  This puts a massive load on the body, which in turn has to produce a massive output of energy to keep the body in whole moving.  

Weight Lifting in a classic sense, has been historically limited to a relatively small amount of joints moving when the loads are place in motion relative to crossfit type of motions. The output is much less in terms of power and cardiovascular loads.  Understand the kinetics of both science is paramount in choosing how to condition the body.  A knowledgeable trainer understands the dynamics of these sciences as it pertain to an individuals abilities and goals.  In a perfect world the is a balance to all these emerging methods.  There too is room for additional methods to include flexibility and mobility in the pursuit of true fitness.  

Yes, there appears to be a tug-a-war between the factions taking sides.  There is simply merit to both methods as they both offer improvements in physiological fitness if done mindfully and intent-fully.
