Defining Your Goals
Muscle Strength is the maximum force you can exert against
resistance at one time. Your muscle strength comes into
play when you pick up a heavy bag of groceries or lift a small
child. It is developed when a localized muscle is worked
both positively (concentric) and negatively (eccentric) at
a resistance great enough to perform only five to eight
repetitions of the exercise before the muscle fails. Each set
of repetitions is followed by a rest interval that typically runs
three times longer than the set. Later, between exercise
sessions, the muscle overcompensates for the stress and
usually increases in both strength and size.
Muscle endurance is the ability to perform repeated
contractions. It comes into play when you cross-country ski
or work on your feet all day. Endurance training addresses
the slow twitch, endurance muscle fibers, which depend on
oxygen for energy. To develop muscle endurance, use low
resistance and high repetitions— about 15-20 repetitions in
each set, three sets to each exercise, working the muscle
only to fatigue.
Muscle Power is the combination of strength and
speed of the muscular contraction. This is often
misinterpreted as:
a) Being directly associated with certain skill or sport; and/or
b) Meaning that you must move fast.
Load is actually a more important factor than speed when
attempting to improve power. When training to achieve
muscular power, pick a resistance that fatigues you in the
3-5 repetition range. When performing these reps, it is
more important to think of contracting the muscles faster
rather than attempting to move faster. Performing sport
simulation exercises usually results in a deterioration of the
motor pattern or skill. The biomechanically sound method
of improving power in your sport is to train for power using
the correct joint movements, as described in this manual.
Then practice the skill associated with your sport, learning to
apply this newly achieved power.
Body Composition is the ratio of fat weight (fat) to lean
weight (muscles, bones and tissue). As you age, the
ratio shifts. The fat weight increases and the lean weight
decreases. Training for muscle strength will generally
increase muscle size and aerobic conditioning will help burn
extra calories. Performing these two forms of exercise,
either at different times or together, will create the greatest
changes in body fat weight.
Balanced Strength and alignment is the result of equal
strength developed in all parts of the body. It comes into
play in your standing and sitting posture, and in your ability
to perform just about any activity safely and effectively.
An over-development of the back will round the shoulders;
weak or stretched abdominals can cause lower back pain.
You want a balance of muscle strength in front and back.
In addition, you need a balance of strength between your
middle, lower, and upper body.
Flexibility is the ability of a muscle or group of muscles
to move the joint through a full range of motion. Flexibility
comes into play when you execute an overhand serve or
stretch for the top shelf in the kitchen. It is a cooperative
movement of opposite muscle groups. When a muscle
contracts, its opposite muscle group must relax for the action
to occur. Increased flexibility means an increased range
of motion, made possible by this simultaneous contracting
and relaxing. Good flexibility is important in protecting the
body from injury and can be achieved through the balanced
strength training programs included in this manual.
Cardiovascular endurance is the ability of the heart and lungs
to supply oxygen and nutrients to exercising muscles over an
extended period of time. It comes into play when you jog a
mile or ride a bike. It is a critical component of overall fitness
and health. Any exercise program must be supplemented
with cardiovascular training.
Reaching Your Goals
To reach your goals you must follow a consistent, well
designed program that provides balanced development to
Your body will do what you train it to do. That’s why it’s important to define your goals and focus on those goals. Here are some
fitness components that will help you define your goals and choose your fitness program.
