Improve your Flexibility for Martial Arts
by Sang H. Kim
Stretch every time you exercise. The only way to improve your flexibility is through
consistent stretching exercises. Every muscle is subject to the myotatic reflex
(stretch reflex) which opposes changes in muscle length, especially sudden or extreme
changes. When a muscle lengthens beyond a certain point, the myotatic reflex causes
it to tighten and attempt to shorten. This is the tension you feel during stretching
The myotatic reflex is desirable because it prevents, in many cases, muscle strains
and tears. Without it your muscles would be allowed to overextend and tear easily.
But it is also undesirable in cases where it prevents you from fully using your
Through stretching, deconditioning of the myotatic reflex takes place. Little by
little, you teach your muscles a new limit of safe extension. This is why stretching
must be slow and consistent. If you overstretch and injure the muscle, you have
to go back to a lower level of flexibility and start over. Set your stretching goals
over a period of weeks or months, not days, for best results.
There are three types of stretching: static, dynamic and ballistic.
Ballistic stretching means bobbing, bouncing or using some type of moving pressure
to stretch the target muscles. Ballistic stretching is not recommended because it
activates the myotatic reflex and causes the muscles to tense, rather than relax.
Ballistic stretching has a high risk of injury.
Dynamic stretching means moving the muscle through its full range of movement. Dynamic
stretching leads to greater flexibility in movement but should be done with caution
so it does not become ballistic stretching. To maintain a correct dynamic stretch,
focus on smooth, even movements that do not shock the muscle. Examples of dynamic
stretches are knee raises, leg raises, arm circles, and trunk circles.
Static stretching is a controlled stretch. A specific muscle or muscle group is
extended to the point of feeling slight pain and held in that position for ten to
sixty seconds. During static stretching, concentrate on relaxing the target muscles
and breathing deeply.
Begin your flexibility workout with several minutes of gross motor activity to increase
your blood flow. Increased blood flow improves the suppleness of the muscles. Then
move to joint loosening exercises followed by dynamic stretches to the get the muscles
moving freely. If you are working only on flexibility, do static stretches next.
If you are training, interspersing periods of static stretching throughout the workout
works best because the range of motion increases as the body warms up. Do some light
static stretches at the end of every workout to relax and refresh your muscles.
• Do not overstretch. A mild sensation of burning or pulling should be felt
in the target muscles. It should be uncomfortable but not unbearable.
• Avoid bouncing during a stretch. Bouncing causes the muscles to tighten and
heightens the risk of injury.
• Follow instructions for exercises carefully. There is right and wrong way
to stretch every muscle. Good flexibility exercises are designed to provide a maximum
stretch with a minimum risk of injury.
• Do gravity assisted stretches with caution and only after fully warming up.
Gravity assisted stretches are exercises like splits that use the force of gravity
to increase the pressure on the stretch.
• You should never feel pain in your joints during stretching exercises. If
you do, stop immediately and discontinue that exercise.
• When doing flexibility exercises that require bending at the waist, always
bend from the hip, not the lower back. The lower back is extremely vulnerable to
• Always increase strength and flexibility together.
