When you are working hard to improve the tone and shape of your body,
the last thing you want or need is to hurt yourself. If you perform an
exercise incorrectly, injury can result - and does, all too often.
Doing too much, too fast is hazardous. Not warming up and/or using
improper form are the most common factors in exercise related injury.
If a specific part of your body hurts after any exercise for
whatever reason, stop doing the movement and check with a trainer. If
no trainer is available put ice on the injured area and if it is not
better in 24 hours, call a doctor.
When working the legs, if you have no previous problems with
your knees or your back and you use proper form, commonly performed leg
exercises such as those following, may be done with no concern.
General Guidelines
When doing any exercises, make
sure you hold your stomach in and keep our torso stable. When extending
legs, make sure not to lock your knees.
Lunges
When you bend downward, do not bend too far
forward or backward. Use no back movement at all. You also want to make
sure our front knee does not go over your tow. If you go over your toe,
you can put a lot of pressure on your kneecap area.
Leg Extensions
This is an exercise performed on an exercise machine. Extend your legs
slowly without locking your knees. If you jerk your legs upward, you
are just using momentum, not your muscles. You will not benefit from
the exercise if done in that manner. Do not use too much weight on this
machine, as it could be hard on the back.
Leg Press
This is an exercise performed on a
machine and is excellent for the legs. It is also less strenuous on the
kneecap area than the leg extension if done properly. Keep your torso
stable, start low on the weight and build up progressively.
Leg Curls
When working the back of the legs, or the
hamstrings, be sure you have the right piece of equipment. For example,
one that is newer and keeps your back from arching. Also, be sure you
are not trying to lift too much weight as this could put undue strain
on your back. Keep your torso stable.
Squats
You can perform squats with free weights or
on a machine. A machine can help guide your back posture, relieving it
of undue stress and assuring proper form. However, with proper form and
free-weights, these are great for the entire leg and should not result
in any discomfort. When doing squats with free-weights, be careful not
to bend or flex your back too much. Keep it stable. The hip, knee and
ankle should be all that moves. You need not - in fact, should not - go
into a deep knee bend. Also, watch your knees to be sure they do not
extend in front of your toes. Think of the squat as a sitting down
motion; as if you were going to sit down in a chair but decided to get
back up. Keep the back straight!
Step-ups
When you begin doing step-ups, start with
a low surface to step onto and no weights. If you decide to increase
the height later, be sure you do not go so high that your knee is
parallel to the ground. As in the squats, you do not want your knee to
go over your toe. Always keep your back straight and upright and be
sure your whole foot is on the surface onto which you are stepping.
Step-ups are great for the legs at any height 4-inches or higher. If
you are uncomfortable at a higher height, lower the stepping surface
again. You will still gain; in addition, the when you incorporate
weights you will challenge the muscles sufficiently.
Aerobic Equipment
General Guidelines
When you are using any kind of
aerobic equipment, you must be sure you do not use any bars for
support. Use bars only for balance, if needed. Keep your stomach held
in and your chest up.
Stair Climbing Machines
These pieces of equipment are good for leg muscles but they can be hard
on the knees. If you were predisposed to knee problems, you would be
better off avoiding a stair-climbing machine. Also note, you can
develop a knee problem with over use of this machine.
Biking
Biking is good for legs and good for the
knees. It takes away the impact of many other exercises. While biking,
be sure that when your leg is down at the bottom stroke you have a
slight bend in your knee.
Elliptical Machines
These are a good choice for
working legs and are very easy on the body. They are non-impact
machines yet works very well for cardiovascular benefits.
