Enhances your level of functional fitness. Your muscles play a key
role in determining whether you can perform the activities of daily
living at home, work, and play. Accordingly, the higher your level of
muscular fitness, the more likely you will be able to do the tasks in
your life without undue fatigue or risk of injury.
Facilitates your efforts to control your weight. The amount of lean
muscle mass you have helps to determine your resting metabolic rate,
which in turn significantly affects the number of calories you burn.
All factors considered, the more muscle you have, the easier it is to
keep your weight within a desirable range.
Promotes bone health. Strength training not only makes your muscles
stronger, it also makes your bones stronger. Performed over an extended
time, strength training has been found to increase bone density. Accordingly,
proper strength training will help to lower your risk of osteoporosis.
Reduces your chances of sustaining both muscular and skeletal injuries.
It's estimated that a significant number of the various injuries that
occur in physical activity could be prevented through a higher level
of muscular fitness. In that vein, strength training can be viewed as
a relatively effective and inexpensive form of personal health insurance.
Slows down the so-called aging process. Strength training enhances
the ability of older adults to perform the daily tasks associated with
independent living. Accordingly, proper strength training can have an
invaluable impact on helping senior citizens maintain their independence
and personal dignity.
Decreases the relative muscular demands of specific tasks. Every physical
activity requires a certain percentage of an individual 's maximal level
of muscular strength. For individuals who become stronger through strength
training, common activities of daily living (e.g., carrying groceries,
shoveling snow, lifting small children) require less effort and are
easier to perform.
Helps treat and prevent lower back pain. Proper strength training
can help reduce the incidence and severity of lower back pain by strengthening
both your abdominal and lower back muscles. By enhancing your postural
stability, keeping these muscles strong can help prevent undue load
forces from being placed on your spine.
Enhances your appearance. The "fit, healthy" look is a
matter of muscle tone, and an improved level of muscle tone is a by-product
of proper strength training. Fortunately, substantial changes in the
level of strength and tone of a muscle can occur in a relatively short
period.
Improves sports performance. Strength training has been shown to enhance
an individual's ability to perform a variety of athletic-related skills.
A higher level of muscular fitness affects not only your capacity to
perform a specific task, but also your ability to continue to perform
that task at an acceptable level over an extended period.
Improves your psychological well being. Strength training has been
found to have a positive impact on your level of anxiety, depression,
and self-esteem. Accordingly, strength training can have a meaningful
effect on the various facets of the mind-body connection.
