Squat
One of the great quotes attributed to the game of golf in describing the essence of the game and
the route to success, is “drive for show- putt for dough”. With reference to weight resistance training
a similar adage might be employed: “the rest is show, squat for dough”. In this manner it might be
said that squatting is to weight-training what putting is to golf After all, when you get down to the
short strokes the winning physique can only be achieved with a solid leg training program.
Of all the movements in the weight-resistance training portfolio squatting potentially offers the
greatest reward while at the same time it presents the greatest concern with regard to injury risk. This
reward-versus-risk concept bas created a major controversy as to whether or not the squatting exer-
cise should be included in the beginner’s weight-training
program. In fact many experts have gone on record as being
opposed to the squat exercise for any weight resistance
training regardless of the experience level.
To Squat or Not to Squat
Proper Form Essential
The question of whether the risk outweighs the reward
can best be answered by catering to the basic requirement
of providing perfect exercise execution in this demanding
exercise. It is crucial that the aspiring weight-training student
take the time to learn the many considerations of
proper movement methodology in order to reduce the risk
of injury. If performed correctly, the squat exercise should
not present any greater risk than any other exercise. The
essential problem of squatting (with respect to injury risk),
is the fact that few trainees learn the correct execution
technique. There can be no denying the fact that improper
execution would leave the trainee highly-vulnerable to injury.
Sensible Resistance Required
Another key aspect to reducing the risk of injury is to
exercise common sense in the selection of the resistance to
be used. Far too often, erstwhile trainees (and this includes
experienced lifters), pack on the plates in effort to move
“impressive” loads. What should be remembered is that
while the squat exercise allows for heavy loading, rampant
optimism has produced many serious injuries. “Overloading”
the bar establishes an immediate danger risk as form is
sacrificed when too much weight is used. Any deviation
from proper form sets the lifter up for both internal and
external injury potential. It is essential that the trainee work
within her/his capability in order to provide proper validation
of a favorable position on the “to squat or not to
squat” question.
One interesting point you may want to bear in mind
when considering the advantages of utilizing proper movement
methodology and proper weight selection in the squat
movement is that while squatting is utilized to develop the
muscles of the legs, only a rare few of the multitudes of
injuries that occur during squatting applications actually
occur to the muscles. A vast majority of the recorded injuries
are related to the lower back and to the knees. This resultant
would suggest that there exists a problem with the
applied methodology rather than with the movement per se.
Considerations for Injury Prevention
There are three basic postures of application associated
with the squatting movement:
- Deep Squat.
- Full Squat.
- Half Squat.
We shall now examine the main points attributed to
each.
Deep Squat
Internal Injury Risk
The deep squat is generally regarded as a “no-no” in
most weight-training circles (particularly in the arenas of
bodybuilding). Although, this posture is frequently used in
weight-lifting events as a manner of approach that provides
the lifter with an opportunity to get under the weight in a
recovery position before attempting to raise the weight
overhead in the “clean-and-jerk” and “snatch” events. With
reference to bodybuilding, and general weight-resistance
training applications however, the deep squat is seen as “too
risky” with respect to both internal (knee and lower back
injury risks), and external (getting pinned beneath the
weight) injury potential.
External Injury Risk
The deep squat posture sees the trainee is an exaggerated almost-touching-the-floor-with-the-seat posture
which stretches the knee ligaments to their most vulnerable position. Particularly stressed in the deep squat position is
the patella ligament which is stretched over the knee-cap. As well, the deep squat position forces the trainee to come
up through a large “sticking-point” while the muscles and ligaments are in their most stretched (and thus weakest), position which exposes the
trainee to a number of injury risks not the least of which is the risk of becoming “trapped” under the
bar.
Keep the Heels on the Floor
If the trainee succumbs to the natural tendency of coming up onto the toes during the descent to
the deep squat position, (commonly referred to as the catcher’s stance), there is considerable risk of
injury as the base of support for the lift is now restricted to small area of the toes. The toes are not
designed to withstand the forces placed upon them in the performance of heavy squats. The catcher’s
stance provides necessary leverage and is very effective in the performance of the duties related to a
baseball catcher. However, the catcher’s stance is not in any Way, effective (and can prove to be extremely
hazardous), to the athlete attempting to perform the squat exercise. If the toes cannot support
the lift, the trainee suffers a knee-buckling response which results in a forward hip thrust action
which creates an arching in the back. The arched-back posture exposes the trainee to a risk of jamming
the facet joints in the lower lumbar region.
Danger of Teetering Backwards
Conversely, if the trainee maintains contact with the floor with the complete region of the bottom
of the feet (including the heels), he/she is in danger of teetering backwards which can produce
injuries to the entire length of the spinal column as well as to the shoulders. The knees are also exposed
to injury if the trainee is unable to effectively initiate and sustain the concentric contraction
phase of the movement. If the trainee experiences difficulty in raising up from thee floor the tendency
is to shimmy upward with the strong side of the body leading the way. Uneven balance in pressure
upon the spinal column can easily produce injuries to the back. In addition, the exterior and medial
cruciate ligaments of the knees are suddenly exposed to high injury risk as well. Clearly, due to the
multitude of injury potential the deep squat position is not recommended.
Full Squat
The next important debate that bas raged on since the discovery of the squat movement is
whether or not full squats should be considered too dangerous and if so should half-squats be utilized
instead. Full squats are determined as squats that provide for the trainee to bend at the hips and
the knees so that the lower legs and the thighs would be at a virtual 90° angle. This posture would
allow for the thighs to be just below parallel to the floor.
Much research has been presented for both the proponents and the detractors of the full squat
application. None of the research supports the contention that full squats create increased injury potential.
The natural movement range for the muscles of the hips allow for a natural application of the
actions of hip flexion and hip extension and thus, affecting a fun squat (thighs just below parallel to
the floor position), represents no specific danger to the trainee.
Advantages of Full Squat
Due to the fact that full squat applications promote the natural execution of hip-flexion, the full
squat approach provides for both reduced injury-risk and enhanced growth and development potential
for the trainee. There are five main components associated with both of these important considerations.
- The efficiency of the applied methodology.
- The speed-of-contraction in the eccentric phase of the
movement.
- The time allotted to the transitory period from the concentric
to eccentric phases of the movement application.
- The congruence of the applied resistance/strength relationship.
- The intensity of the neural-impulse activity directed to the
muscles that comprise the region of the hips.
There will be more information provided on these areas of
consideration in the subsequent section on exercise execution.
Half Squat
Half squats is the application which sees a 45° angle formed
between the thighs and the lower legs. While it would seem logical
that the half-squat would be much safer than the full squat,
an analysis of the two squat positions reveals that there is in fact,
greater pressure exerted upon the knees during the transitory
period from the eccentric to the concentric contraction phases
of the movement during the half squat application than is experienced
during the execution of the full squat. In addition, due to
the fact that half squats increase the activation of the muscles of
the knee-joint rather than the muscles of the hip-joint, and due
to the fact that the movement application is performed with a
reduced range-of-motion, the half-squat application can be considered
more dangerous, and far less effective (with respect to
growth and development potential), than the full squat application.
Injury Risks Associated with Returning the
Weight
It should be noted that there is a high-risk of injury associated
with returning the weight back onto the rack. At the conclusion
of a set the muscles are drained and the trainee is left
staggering back to the rack. The primary concern now is getting
rid of the weight and as quickly as possible. This is where the
problems arise. In their quest to “dump” the weight quickly, the
trainee often commits serious flaws in technique. The most
common error is that of using a thrusting action to throw the
weight back onto the rack.

Negative Results of Thrusting
In applying the thrusting action, the trainee is encouraged to
bend forward which encourages a dropping of the head action.
The spin is bent and the force vector now hits directly upon the
lower lumbar region. In addition, when there is a desperate need
to toss the bar back onto the rack the trainee misses the target
with gruesome results. The back can become more bent, establishing
increased injury risk to the spinal region and to the
knees. External injury risk is also increased significantly when ill
advised return actions are employed.
In order to ensure the safest, most efficient return of the
bar the trainee would be when-advised to walk the bar all the
way back to the rack using a vertical posture featuring a rigid
back and with the head held up. Once the bar is in contact with
the columns of the rack the trainee should now utilize hip and
knee flexion in lowering the bar onto the safety pins.
Proper Pin Placement
Note as well, the pins should be placed lower the shoulder
height in order to provide for the safe lift-off and return of the
bar. Most trainees utilize the below shoulder height position in
manner of providing for safe lift-off. Placing the pins higher
than shoulder height forces the trainee to rise up onto their toes
to lift the bar which is not an advisable practice. However, the
lower-than-shoulder-height placement of the pins often invokes
injury due to poor technique in the returning of the bar to the
pins. Frequently, the fatigued trainee will attempt to “dump” the
bar back onto the pins rather than lowering the bar by the utilization
of hip and knee flexion. The “dumping- action forces a
rounding of the back posture which establishes a high-risk position
of the body. The lower the pins, the more exaggerated the
lowering of the head and the rounding of the back response
which accentuates the risk of injury.
Caution Required in Returning the Weight
Treat the return of the weight with the same respect as the
rest of the exercise execution in order to lower the high risk of
injury associated with returning the weight. Returning the
weight to the safety pins is a matter of simply standing up
straight and then affecting the squat move by applying hip and
knee flexion while maintaining a straight and rigid position of
the back with the head held erect in lowering the weight slowly
and carefully onto the provided safety pins. It is – essential that the trainee reserve enough strength to
affect a squat (partial) movement in order to ensure the safe return of the weight.
Avoid “Dumping” the Weight
If the trainee is exhausted at the completion of the set then, quite naturally, he/she will want to
get rid of the weight in fastest, easiest manner possible. The easiest and fastest maneuver is the one
that sees the trainee bending at the hips (essentially establishing a “good morning” posture) and
“dumping” the weight onto the safety pins. To perform the “good-morning” posture with the loads
that are used for the squat exercise would be to send out an engraved invitation to injury. It requires
strong muscular contraction to combat the force of gravity; as such, it would be advisable to avoid
reaching a state of motor -unit exhaustion in the muscles of the legs in order to ensure that a proper
squat movement could be executed in manner of providing for the safe, efficient return of the bar
onto the rack.
Summary of Correct Exercise Execution
- Face the bar assuming a natural shoulder-width stance with the feet positioned with the toes
slightly outward.
- Utilize slight hip and knee flexion in order to achieve the desired preparatory posture. Adjust the
stance so that the bar is placed across the shoulders. Do not let the bar slide down the back during
the movement application. Frequently, the trainee, sensing the slipping of the weight, will
lean forward in effort to keep the bar in place. The forward lean position exposes the lower lumbar
region to in jury risk. As well, if the weight is placed too low on the back instead of on the
desired location atop the posterior region of the shoulders and across the upper portion of the
trapezius, the resistance will be supported to a large extent with the arms. With the shoulders in
the stretched (and thus vulnerable) position, they can easily become stretched or tom.
- Assume a natural grip with the hands placed just slightly-wider than-shoulder-width. Frequently,
trainees use a wide-grip that sees the arms almost fully extended and the wrists wrapped around
the bar. This position of the arms and the hands creates a natural tendency to roll the shoulders
forward. The rolling forward of the shoulders encourages a lowering of the head which further
encourages a resulting rounding of the back posture which, as outlined, creates a high-risk of injury
for the trainee. The wrist-around-the-bar position of the hands also encourages the trainee
to exert greater pressure on the knees as the force vector now comes down over the area of the
knees instead of being driven down through the area of the gluteals and hamstrings.
- Initiate the concentric contraction phase of the movement by utilizing knee and hip extension
and drive off the rear portion of the feet while making certain to keep the head up and the hips
down.
- You will want to utilize strong neural impulsing into the powerful quadriceps, hamstrings, and
gluteals in order to correctly execute the power phase of the movement. You will also want to
avoid “mapping-out” at the completion of the concentric contraction phase as the snapping action
could create a hyperextension effect upon the patella region. The snapping action could also
duress the lower lumbar region due to a sudden jamming of the facet- joints.
- Keeping the body straight with the back in a rigid, and flat position, and with the head held erect
with the chin up, slowly begin the eccentric contraction phase of the movement by Utilizing hip
and knee flexion. You will want to remember to avoid the tendency of raising the heels off the
floor during the execution of the eccentric contraction phase.
- Lower the weight slowly, and evenly, while maintaining a flat, rigid posture of the back. You will
need to concentrate fully in order to maintain the desired head-up/-hips-down posture.
- Slowly complete the eccentric contraction phase of the movement by utilizing hip and knee flexion
until the thighs are parallel to the floor. You will have to concentrate fully on avoiding the
natural tendency to rise up onto the toes during the completion of the eccentric contraction
phase of the movement.
- As you reach the finish position of the eccentric contraction phase of the movement you will
need to resist the urge to bounce into the subsequent concentric contraction by pausing for a full
count at the completion of the descent.
Keys to the Lift
- Utilize intelligent weight selection. Impress the crowd with you technique; not how much weight
it took to put you in the hospital.
- Apply slow speed-of-contraction movement applications.
- Concentrate fully throughout both the concentric and eccentric contraction portions of the lift.
Remember, is easy to forego proper form when performing the squat exercise. You must stay
mentally sharp during the execution of this exercise or you will pay a severe price!
- If you feel that you are in danger of breaking form if another “rep” is attempted, then simply
abort the set. Do not risk permanent injury in order to meet the predetermined quota of “reps”
you may have established for yourself.
- Remember to maintain the desired exercise posture and execution:
- Feet flat on the floor at all times.
- Back is to be held in a flat and rigid position at all times.
- Remember to keep the head erect and the hips down. Avoid lifting the head too high, as this
encourages a hyperextension posture of the back.
- Utilize hip flexion don’t just rely upon flexion action of the knees.
- Be sure to continue the eccentric contraction phase of the movement until the thighs are positioned
parallel to the floor.
- When you drive upward with the weight do so under control in order to avoid the general snapping
out action of the knees which creates a hyperextension effect upon the patella ligament.
- Utilize strong neural impulsing into the muscles that comprise the region of the hips in order to
ensure the strongest muscular response in effort to provide the safe, efficient execution of the
movement.
