One
of the most common ways to learn how to exercise in a gym is by watching others
go through their workouts. I’m sure most of us, at one time or another, have tried
an exercise after watching someone else perform the movement. But just because
someone with a buff body is doing an exercise does not mean that particular
exercise is effective. In fact, there are many exercises that seem to be
producing a desired outcome, yet aren’t really creating a beneficial
physiological response. If you’re doing certain exercises because you saw other
gym goers do them, you might want to consider trying these exercises
instead:
If you want to work your chest…
Instead of This: Standing Chest Flys With Dumbbells

Do
This: Lying Flys

When
the goal is to strengthen the chest muscles, the load should be placed directly
into the pectoralis major and minor, as is the case with push-ups, the bench
press, pec-deck machine, or flys with dumbbells or
cables. This is because the pull of resistance is lined up directly with the
muscles, so when they shorten they are generating the greatest amount of force
to move the shoulder joint. When doing chest flys
while standing and holding dumbbells, the deltoid muscles of the shoulder are
doing most of the work, while the pectoralis major or minor act as secondary
muscles, which makes it more of a shoulder exercise than a chest exercise. If
an instructor has you doing this exercise and says
it’s for your shoulders, however, that’s fine.
If you want to work your glutes…
Instead of This: Wall Sit
Do
This: Glute Bridge

The
purpose of squats is to strengthen and tone the muscles of the butt, thighs and
hips. The most effective way to strengthen a muscle and develop definition is
to take it through a full range of motion (ROM), which includes lengthening as
well as shortening the involved muscle fibers. During a wall sit, an exercise
featuring an isometric (non-moving) contraction, muscles are shortening, but
they are not making the transition from lengthening to shortening because only
a finite amount of muscle fibers are engaged. Compare that to an exercise like
a regular squat where the muscles transition from lengthening to shortening
through a complete ROM, which covers much more distance and allows more work to
be completed. A wall sit makes you feel like your muscles are burning, but that
is because they are holding static, non-moving contractions. The actual
strength benefits, however, are minimal. The glute bridge
is a better option because they take the hips through a full ROM. The benefit
of lying on the ground is that it focuses the work on the hip extensor muscles
of the glutes, hamstrings and adductors.
If you want to work your inner thighs…
Instead of This: Plié Squats

Do
This: Lunges

Plié
squats are often done to create the perception of working the adductor muscles
of the inner thigh. When the feet are in a plié position, the hips are in
external rotation, which does lengthen the adductor muscles of the inner thigh.
Holding this position tricks you into feeling your inner thigh because those
muscles are being stretched during the motion. However, just because you feel a
stretch doesn’t mean those muscles are doing more work. Understanding how a
muscle works during gait can help us determine the best way to train that
muscle with exercise. The adductor muscles of the inner thigh are responsible
for creating hip flexion and extension during gait. They can bring the leg
closer to the midline of the body (adduction), but should be trained with
exercises that emphasize extension and flexion of the hip to help prepare the
muscles for the forces they experience during normal movement patterns. Plié
squats won’t necessarily increase your risk of injury, but they don’t provide
the best option for training the adductor muscles. Don’t be fooled—if you
really want to strengthen and tone your inner thigh muscles, do single
leg step-ups, lunges or single-leg
squats to engage
all of the hip muscles.
If you want to work your inner and
outer thighs…
Instead
of This: Lying Inner/Outer Thigh Leg Lifts


Do
This: Ice Skaters

Lying
on your side and lifting your legs off of the ground can help you feel like
you’re using the muscles of the inner and outer thigh, but this is not the
case. Again, we need to understand how these muscles actually function during
gait to determine the most effective way to use them during exercise.
Traditional anatomy teaches that the muscles of the outer thigh work to move
the leg away from the midline of the body. However, during the gait cycle the
muscles that move the leg away from the body actually work to stabilize the
body when you’re standing on one leg. For example, when you’re walking, your
right outer-thigh muscles stabilize your body when you are balancing on your
right leg and your left leg is swinging through the air. The most effective way
to strengthen your outer-thigh muscles is to do single-leg exercises like
step-ups, lunges or ice-skater (lateral) bounds. While leg lifts are unlikely
to cause an injury, they are not the best use of your limited exercise time.
If you want to work your
abs…
Instead of This: Frog Leg Crunch

Do
This: Medicine Ball Chops

The
idea behind frog-leg crunches is that placing the hips in an abducted position
(with the upper thighs and knees touching the floor) will recruit the lower
abs. The standard crunch involves using the abdominal muscles to roll the rib
cage toward the pelvis, which can strengthen these muscles, but does not train
them the way they are actually used during upright movement patterns. If
your ab
muscles were
really responsible for flexing your spine, you would walk around bending
forward every time your foot hit the ground. During gait, the six-pack muscle
of the rectus abdominis is involved in decelerating the anterior (forward)
rotation of the pelvis, while the external obliques
are responsible for assisting with rotation of the trunk. While lying on the
floor to train the abs can create the perception of muscle involvement and can
be useful for individuals training for specific appearance-based goals, if you
want to train your body the way it was actually designed to function, then
consider training your core from a standing
position. Medicine
ball chops, for example, involve the muscles of the hips, thighs, back and
shoulder, which can all be considered core muscles because of their attachments
to the spine and pelvis. Start with the medicine ball near the right hip, sink
into a quarter squat, and then use the hips and arms together to push the ball
overhead before bringing it down to the left hip; alternate from side to
side.
If you want to work your calves…
Instead of This: Toe Raises

Do
This: The Heisman

Standard
toe raises are great for strengthening and toning the calves because this
exercise focuses on the concentric action of muscle shortening, which can
increase size and definition. However, the function of the calf muscles during
dynamic movements such as walking, running or jumping is to help decelerate the
force of the body hitting the ground. As a result, the calves can experience
extremely large lengthening forces. This means that exercises that focus on the
shortening action of the muscles do not adequately prepare the muscles for the
forces they frequently experience. Toe raises can make a calf stronger, but
this exercise also increases muscle tightness, which can be a liability during
explosive movements when the calves are required to rapidly lengthen as the
foot hits the ground. In addition, people who wear shoes with an elevated heel
keep their calves in a shortened position all day. Doing additional exercises
to shorten the muscle could lead to a muscle imbalance along with potential
knee or hip soreness. If you want to strengthen and tone your calves,
adding sprints or agility
drills to your workouts, such as the Heisman,
are better options.
If
you only have a limited amount of time to exercise, it’s worth taking the time
to take a close look at your exercise selection and focus on the ones that will
provide the greatest benefits. If you have any questions about how to perform
these exercises, consider investing in a few training sessions with an ACE
Certified Personal Trainer who can provide the guidance you need to meet your
fitness goals in the shortest amount of time possible.
