Crossfit works. I will be the first to tell you that
crossfit is one heck of a workout and that it gets people “in shape.” With that
said, it is not made for athletes, in fact it could be more detrimental for
athletes than beneficial. There are tons of reasons as to why crossfit is a bad
choice for athletes, as opposed to conventional training; in this short piece I
will try to bring to light some of the main ones.
First, I
would like to touch on what every athlete needs in order to compete at the
highest level. These attributes include: strength, power, speed, endurance,
work capacity/low level fitness, coordination, kinesthetic sense, etc. Strength
is defined as the maximum amount of weight that can be lifted, usually trained
in reps of 1-3, sometimes 1-5. Power is work divided by time, so basically it
is how fast you can move a load; max power is usually reached on rep 2 and
diminishes by rep 3. Speed is the maximum velocity attainable at a short moment
(usually no longer than 6 seconds.) Work capacity is being able to repeat bouts
of some type of movement (lifting or movement.)
The primary
reason involves the overall idea of crossfit. Crossfit involves many lifts,
such as: cleans, jerks, snatches, plyometrics, squats, deadlifts. Those six
cornerstone movements that I just listed are usually referred to as the principal
strength and power lifts/exercises. As I explained prior, strength and power
movements are best trained as maximum efforts, usually lasting 1-5 reps. In crossfit
however, these same movements are done in sets of 15-20 and sometime for max
reps in an allotted time. So, how does that build strength and power? It
doesn’t, instead it builds work capacity. Now, as an athlete would you rather
build work capacity forcing up reps of a strength/power movement, or on the
field running plays/drills? That answer is simple, unless you are training to
be a crossfit champion, then your work capacity needs to be done on field in
sport specific training.
Along the
same lines as the training goals I explained comes the precision that these
lifts are performed. Most of the main strength/power movements need to be
preformed with about 95% perfect form, in order to get the proper benefits. I
always tell my athletes that I care more about how the weight is lifted than
how much or how many times a weight can lifted. In the crossfit setting this
notion is completely reversed and all emphasis is put on more reps, more
weight, go, go, go! When weight and reps is the goal, form is going to suffer
greatly.
When you
combine my two previous thoughts, you get one of the most important reasons as
to why athletes do not need crossfit, and that is chance of injury. Every
crossfit competitor I know has had a barrage of injuries, and that is only in
the present, I cannot fathom the level of their injuries 10 years down the
road. When the human body is put through the sessions of crossfit over and over
it gets beat down and is not allowed to recover. After all, we get
stronger/faster/more powerfull/etc. when we recover from the training we do,
not while we are beating ourselves down. In crossfit there is no programmed
progression and no modes to allow recovery and super compensation (recovering
to a level higher than you started.) It doesn’t take long for this to catch up
and cause injury. Our single most important goal as an athletic performance
coach is to put a better athlete on the field; coach crossfit can’t put a
better athlete on the field if they are injured.
There are
many more reasons why crossfit is not meant for athletes. Most of which are
more in depth and involve program design and also the human brain and how it
reacts to various types of training. These that I have covered here are the
simplest and hopefully most persuasive.
