2. Behind-The-Neck
Pulldowns This
exercise is done to work the muscles of the back. While the exercise itself is
actually effective for working the back, the problem with the exercise lies in
what it can do to your shoulders.
In the previous exercise,
I talked about internal rotation of the shoulders. The problem with the
behind-the-neck pulldown lies in "external rotation." Going back to the arms out
to the side example, instead of pouring water forward, rotate your arms backward
so that your palms are facing up. It's basically the opposite movement to
internal rotation.
To do the behind-the-neck
pulldown as normally instructed, you must externally rotate your shoulders as
much as possible. This is a very delicate position for your shoulders. The
supporting muscles of the shoulders (known as the rotator cuff) are not in a
good position to stabilize the joint and injury to those supporting muscles can
result, which can lead to further injury in the connective tissue of the joint.
On top of that, since most
people do not have enough shoulder flexibility to get a straight line of pull
behind the neck, they must bend their neck forward to even do the movement. This
can result in neck strain on top of shoulder strain.
This information also
applies to the behind-the-neck pull-up exercise. The mechanics of the movement
are exactly the same, the only difference being you're pulling yourself up
instead of pulling the weight down.
Stick to exercises that
are in front of the body, such as front pulldowns, close-grip pulldowns and
pull-ups to the front.

3. Behind-The-Neck
Shoulder Presses
The Behind-The-Neck Press
gives us the same shoulder issues associated with the Behind-The-Neck Pulldown.
To do the movement, you must maximally externally rotate the shoulders. Again,
this places the shoulders in a very vulnerable position, which can easily result
in strain in the Rotator Cuff muscles.
Also, as with the
pulldowns, most people simply don't have the necessary shoulder flexibility to
get a straight line on the movement - they must tilt their head forward to get
the bar behind it, adding greatly to the possibility of injury.
Stick to the military
press and the dumbbell press for your shoulder pressing movements.

4. Stiff-Legged Deadlifts On A Bench
The Stiff-Legged Deadlift,
properly done, is actually a very good movement for the hamstrings, glutes and
lower back. The problem comes when, in an attempt to increase the stretch on the
hamstrings, the exercise is done standing on a block or bench.
To get the most stretch on
the hamstrings and to protect the lower back from injury, an arch should be
maintained in the lower back during the movement. It's extremely difficult to
maintain an arch in the lower back when you are stretching down as far as you
can towards the floor with a barbell pulling you down.
Without the arch, as a
natural result, the spine will flex and the supporting muscles of the spine will
relax. This places much of the tension of the exercise directly on the
connective tissue and bones of the spinal column rather than the supporting
muscles, which are stabilizing the spine. In an effort to get more stretch on
the hamstrings, you instead compromise the support structures of your lower
back.
To get more of a stretch
on the hamstrings without standing on a bench and compromising your lower back,

5. The Sit-Up
If you enjoy having a
pain-free lower back, the regular floor sit-up is a good exercise to avoid. When
you do a sit-up, the mechanics of the movement and position of your body throw
much of the torque of the movement onto your lower back. Your hip flexors pull
directly on your spine in order to raise your torso off the floor when you do
the exercise, leading to strain in the lower back area.
To top it off, the
abdominal muscles (the real target of the exercise) are only worked
isometrically. This means they don't actually contract and move, they just work
to hold the torso steady while the hip flexors do the pulling. This is not a
very effective abdominal exercise.
You will be far better off
performing direct abdominal-training movements such as crunches, ball crunches,
cable crunches, etc. These exercises directly target the abs without throwing
excessive tension on the lower back.

An excellent exercise for
the abdominals that is similar in look to the regular sit-up but focuses on the
abs is the Abdominal Sit-Up. You can read more about it here:

The exercises you do have a profound effect on your training and your health. Be
sure to choose exercises that will help you move forward towards your goals and
not set you back through injury.
