Olympic-style
weightlifting is becoming a staple in every gym across the country, all
thanks to the uprising of CrossFit. The downside is that most of the
everyday gym goers have no prior experience of Olympic weightlifting
other than what they see others doing in the gym, in videos, or during
the CrossFit games. Now, in respect of CrossFit it has single handedly
put more barbells in hands and people in gyms than anything in history.
One
of the most often butchered lifts seen in a gym is the Power Clean. As
mentioned before we live in a monkey see-monkey do world. Without
knowing anything about the lift and the dangers of improperly performing
it, people want to load up an impressive amount of weight and just
heave it up in any way possible. Check your pride at the door and save
your body for years to come.
The
Power Clean involves a few different movements combined into one,
closed kinetic chain, explosive movement.The first movement is pulling
the weight off the floor as done in a deadlift. The initial pull is
performed with a flat back, high chest, and eyes looking forward.
As the weight is pulled off the floor, keep the back flat, push the
knees back making the bar come up the shins and back instead of up and
around the knees. As the bar clears the knees, an immediate change of
speed occurs as the hips, knees, and ankles are explosively extended,
and the shoulders are shrugged causing the person to jump off the
ground. As soon as the body becomes tripled extended, the High Pull
occurs with the elbows flexing and arms being horizontally abducted. At
the top of the High Pull, the person then drops under the bar to catch
or “rack” the weight on top of the shoulders. To catch the weight, the
elbows flip under the bar as the person drops(squats) under the bar into
flexed hips, knees, and ankles. The weight should be caught on the
heels with the hips back, much like the position of a front squat.1
The
lift should be performed starting and ending in the same spot. If the
athlete is jumping forward, the hips are likely not getting extended
during the second pull, creating the bar to be out and away from the
body.2 Flexibility
and joint mobility play a huge roll in the execution of the Power
Clean, which can make the lift a total disaster from the start, because
the lifter is unable to set up on the bar correctly for the initial
pull. This creates back issues by pulling with a rounded back instead of
properly using the legs. Beginners should start light and focus on
technique first and foremost. As technique gets better, the bar will
begin to fly and the amount of weight you are able to handle will go up.
The hips are able to create a tremendous amount of power so remember,
bring the hips to the party.

My main problem with Olympic lifts being misused, is when I use the volume being increased above 5 reps. The power clean is meant to be powerful, and requires a lot from your central nervous system. The CNS starts to fatigue pretty quickly, between 3-5 reps. When you push past that fatigue, that's when will see a ton of injuries.
