Hack Squats

Hack Squats

The hack squat exercise provides an opportunity to implement a different squat application into
the student’s leg program. The back squat is often categorized-as a power movement when in reality
it should definitely not be considered as such. The major benefit attributed to the back squat exercise
is that it allows for a potentially safer squatting variation. The hack squat exercise is performed on a
hack squat machine which features a reclined weight-track, shoulder harness, and a back rest which
provide for enhanced balance and a reduced angle-of-exertion (with reference to the considerations
associated with the line-of-gravity) which allows for a facilitated movement application.

The back squat exercise is of particular value to those athletes who have suffered shoulder injuries
and cannot support or balance the bar across the shoulders as required in the conventional squat
movement application. While the back squat is generally regarded as presenting less of a risk than the
regular squat, it carries significant risks of its own.

Movement Analysis
What should be noted is that the hack squat exercise places specific demands upon the trainee
and should not automatically associated with the conventional squat. While there are some similarities
of exercise execution, there are also a number of distinct differences that require specific movement
methodology on the part of the trainee. Remember, weight-resistance training is highly-specific
and as such, each exercise places specific demands of proper exercise execution upon the trainee.
The hack squat exercise places a different emphasis upon the muscles that surround the hip-joint
and knee-joint. Of particular significance is the fact that the unique angle of the foot bed places a
unique emphasis upon the ligaments and tendons of the knee. Particularly vulnerable are the patella
ligament and the quadriceps tendon which attaches to the patella bone on the front of the knee.

Resistance Selection
It should be noted that just because a trainee might be strong in the conventional squat, it should
not be taken for granted that heavy poundage can be applied to the hack squat movement. The earnest
weight-training student would want to take the time to build the strength up in the specific fibers
called upon in the hack squat exercise by escalading the resistance gradually before attempting heavy
loads.

Proper Foot Placement

Dangers of Feet Too Close
The correct stance would see the feet placed
upon the platform in a slightly forward position and
spaced at slightly wider-than-shoulder-width distance
with the toes pointed in a slightly outward
position. If the feet are positioned to close to the
body, there will be tremendous pressure exerted
upon the knees during the eccentric contraction
phase of the movement. Also, with the feet positioned
too close to the body, there is tendency to
come off the back rest and use a hip-thrust action
during the initiation of the concentric contraction
phase of the movement. Coming off the back support
and employing a hip-thrust action induces the
force vector to hit directly upon the lower lumbar
region.

Dangers of Feet Too Far Apart
Conversely, if the feet are positioned too far in
front of the body, there is a tendency to apply an
exaggerated hip-thrusting action in order to maintain
contact with the back rest. The exaggerated hipthrust
action can force the trainee up onto the toes,
which forces the trainee to assume an arched-back
position. Arching the back results jams the facet
joints in the lower lumbar region. Complicating matters
is the fact that the force vectors now directly
attack the vulnerable spinal region.

In addition, if the feet are positioned too far in
from of the body there is natural tendency to lower
the head during the eccentric contraction phase of
the movement due to the angle formed between the
upper torso and the legs. A dropping of the head
action encourages a rounding of the back response
which further exposes the lower lumber region to
injury.

Range of Motion
A slightly-wider-than-shoulder-width foot
placement (with the feet pointed slightly outward) is
recommended because this posture allows for a facilitated full range-of-motion movement application.
As well, if the feet are spaced too close together there is greater felt in the knee. Of particular
concern is the lateral cruciate ligament of the knee. As well, close feet placements encourage hipthrusting
and a following rising up onto the toes action which, as outlined, is strongly advised against.
Another crucial point needs to be made: the angle of the foot platform should be slight as a correlation
between the severity of the angle and the amount of pressure that is exerted upon the knees during
the movement application exists.

Summary of Correct Exercise Execution
- Assume the proper preparatory posture by placing the feet upon the angled platform in a
slightly-wider than shoulder width stance. The feet should not be placed too far in front of the
body or too close to the body. The correct distance is determined top be that placement which
does not:

- Exert undue stress upon the knees;
- Force the body away from the back-rest;
- Induce the trainee to rise up onto the toes.

- Assume the proper preparatory posture by aligning the body beneath the shoulder harness while
establishing a rigid and flat -back posture with the head up and the chest out. You will want to
make certain that the entire length of the back (not just the upper portion), is in touch with the
back rest.
- Begin the eccentric contraction phase of the movement by utilizing hip and knee-joint flexion
and slowly lower the weight to the bottom of the natural range-of -motion of the hip flexion action.
The natural ROM would be one that allows for a facilitated movement application that encourages
the activation of the muscles of the gluteals, upper hamstring region, and the quadriceps.
It is important to produce high-activation of the muscles in order to reduce the exertion
upon the knee-joint.
- You will need to concentrate fully on applying strong neural impulsing into the gluteal region as
well as the area of the posterior upper thighs in order to avert the natural tendency to allow for
gravity to take over control of the movement in the eccentric phase which results in a bouncing
action at the conclusion of the descent. Bouncing at the completion of the eccentric phase exerts
tremendous pressure upon the knees which can easily cause injury to the quadriceps tendon and
the patella ligament.
- In order to establish the correct movement application in the concentric phase, it is imperative
that the trainee maintain contact with the platform with the entire foot (not just. the toes), and
drive off the rear portion of the feet. If the heels are raised up, the exertion will be applied with
the toes, which places added pressure upon the ligaments of the knee.
Please note, however, that you should not over emphasize the pressing action of the rear portion
of the feet by raising the toes off the platform (dorsi flexion). If the toes are raised off the platform
it encourages a hyperextension of the knee-joint which creates high injury-risk to the patella
ligament as well as the quadriceps tendon.
- Remember to avert the natural tendency to apply a hip-thrusting action into the initiation of the
concentric contraction phase of the movement by driving off the heels and by maintaining contact
with the back rest with the entire back. Note: some back rests do not extend down to the
full length of the back. In such a case, the trainee will have to be extra cautious to maintain the
correct flat -back posture and to keep as much of the back jammed against the back rest as possible
in order to encourage a stabilized posture of the highly-vulnerable lower lumbar region.
- Raise the weight slowly through the concentric contraction phase of the movement by utilizing
well-controlled knee and hip-joint flexion. You will want to avoid snapping-out at the completion
of the lift as this action will encourage a hyperextension action of the knee-joint. Snappingout
also encourages a resulting hip-thrust action which creates an injury risk to the lower lumbar
region.

Keys to the Lift
- The first step to the safe, effective utilization of the back sq~ exercise is to recognize from the
outset that the back squat exercise is not a power movement per se. Heavy poundage are not required-
and in fact are discouraged- in this exercise.
- Pay strict attention to applying the correct stance, body posture, and exercise execution throughout
the performance of the exercise or injuries are a virtual certainty.
- Utilize slow speed-of-contraction movement applications
- Press off the heels of the feet and not the toes.
- Keep the back Bat and rigid, and maintain contact with the back support throughout the movement
application.
- Keep the bead up and the hips down in effort to avoid the natural tendency of dropping the
head during the descent.
- Utilize strong neural-impulsing in effort to ensure maximum activation of the involved muscles
in order to reduce the exertion upon the knee-joint.
- Avoid bouncing at the conclusion of the eccentric contraction phase of the movement.
