Are you using potentially dangerous exercises in your
workout? You have to be very careful with strength training equipment because
it may not be the most effective or functional available. How do you know that
the exercises you are performing are safe? Found below are some potentially
dangerous exercises with suggestions on how they should be done correctly or
avoided completely.
Sit-up
Traditional abdominal exercises such as the sit-up, incline
sit-up and hip-raises are exercises that are used to train the obliques and the
upper and lower abdominals.
They are performed by first anchoring the feet on an
abdominal board which prevents you from sliding back then raising your
shoulders up towards your feet, tensing your abs at the top of the movement.
Slowly lowering your shoulders back down and then completing the movement
again.
The dangers of performing this movement are the shearing
forces on the vertebrae and spinal discs when you have a flexed and rounded
spine. In this position, the pressure is mostly placed on a very small area of
the disc area, which can cause small ruptures. The safest and most productive
way to train the abs is to use the brace and hollow technique. This is a basic
isometric exercise that helps strengthen the abs and the muscular girdle around
your waist.
Pec Deck
The pec deck is an exercise that trains the chest
(pectorals) and shoulder (front deltoid) muscles.
This exercise is performed by sitting at the machine with
your back flat against the back pad. Placing your forearms on the padded levers
and position your upper arms parallel to the ground. Pushing the levers slowly
together and squeezing your chest muscles at the end of the movement. Return
slowly to the starting position.
This exercise is potentially dangerous because it places the
shoulder into one of its least stable positions, the dislocation position.
Because of the extreme position when performing this exercise at the starting
position it can also cause tearing of the ligaments and injury to the rotar
cuff tendons.
More effective and less dangerous is the bench press,
keeping the arms at shoulder width and exercising in the strongest range of
motion (partial reps) and the parallel bar dip with the elbows out.
Behind the neck Press
This exercise trains the neck (traps) and shoulder (deltoid)
muscles and is performed by placing a loaded barbell onto your upper back just
above the trap muscle.
This exercise is done by standing with your feet about
shoulder width apart. Placing your hands on the bar about three inches wider
than the width of your shoulders. Pushing the bar overhead to arm's length,
holding and then slowly lowering back down to your shoulders. This exercise can
also be done seated. Try performing it in a smith machine or power rack for
added safety.
This is an exercise that places the shoulder joint into the
dislocation position and the range of motion puts unnecessary stress on the
rotator cuff tendons of the shoulders.
Many trainees may experience injuries from this
behind-the-neck movement. As with before stick with dips and bench presses for
your shoulder work.
Dead lift
The dead lift is a compound movement that works the hips,
lower back and also exercises the hamstrings and glutes (buttocks).
You can perform the dead lift by approaching a loaded
barbell and taking a stance about as wide as your shoulders. Grip the bar so
that the arms are slightly on the outside of your thighs. Your feet should be
pointing straight forward with the shins about two to three inches from the
bar.
Heave the load upward using the hips and lower back keeping
the back straight and the bar as close to the shins as possible. At the top of
the movement hold for a few seconds and then lower the bar to the starting
position.
The exercise has a knock-on growth effect on the whole body
when worked hard. The problem with the lift is that if the spine becomes
rounded during the lift it then becomes dangerous. Because of the forces
working on the vertebrae and the spine injuries may occur.
A lot of these problems can be solved by keeping the back as
straight as possible during the lift and keeping the bar held close to the body
during the lift as the forces are then not that excessive.
Leg extensions
Leg extensions are arguably one of the most popular leg
exercises for strengthening the quadriceps (thigh) muscle.
These are done by using a leg extension machine and sitting
in the seat with your feet hooked under the padded lever. Raise the weight with
your legs until they are pointing straight out in front of you. Hold briefly, and
then slowly lower the weight back to the starting position.
Leg extensions are a potentially dangerous exercise because
when only the shin is in motion, the exercise draws the patella back onto the
femur increasing joint compression forces, which can damage the connective
tissue and the ligaments supporting the knee joint. It can also cause anterior
knee pain so people with existing knee problems may aggravate them by doing
this exercise.
For greater safety and equal effectiveness, try doing the
Squat, Leg Press, and Lunge for safer and more functional use.
