The
superficial group
Distal attachment for all superficial muscles:
Posterior of heel (calcaneus bone) via the Achilles tendon
Gastrocnemius: The two bulges of muscle
that people normally associated with the calves, used for rapid
movements during running and jumping to lift the heel and push off
the toes. They also help steady the legs when standing. High heels
can enhance the shape of gastrocnemius, but are murder on the toes.
| Proximal attachment: |
Posterior lower femur |
| Distal attachment: |
Posterior of heel via Achilles tendon |
Soleus: lying deep to the gastrocnemius
and also used to point the toes and lift the heels during more relaxed
movements such as walking.
| Proximal attachment: |
Posterior upper fibula
Upper tibia |
| Distal attachment: |
Posterior of heel via Achilles tendon |
Plantaris:
very weakly assists in pointing the toes and flexing the knees.
| Proximal attachment: |
Posterior lower lateral femur
|
| Distal
attachment: |
Posterior of heel via Achilles
tendon |
The deep group
Popliteus:
Unlocks the knee and weakly flexes the knee.
| Proximal attachment: |
Lateral lower femur |
| Distal
attachment: |
Posterior superior tibia |
Flexor Hallucis Longus: Flexes the big toe and supports the
arch of the foot.
| Proximal attachment: |
Posterior fibula and the connective
tissue between tibia and fibula |
| Distal
attachment: |
Underside of big toe bone |
Flexor digitorum longus: Flexes the four small toes and supports
the arch of the foot.
| Proximal attachment: |
Posterior tibia and fibula |
| Distal
attachment: |
Underside of four small toe
bones |
Tibialis posterior: Inverts the foot (tipping
the pinky toe down and the big toe up) and points the toes.
| Proximal attachment: |
Posterior tibia and fibula |
| Distal
attachment: |
Underside of the foot |

Always warm up and stretch thoroughly before
any activity involving running or hiking (see
calf stretches and exercises).
Always cool down by jogging then walking followed
by the calf stretch after strenuous activity.
Terrestrial exercises will work these muscles
as they support the weight of the body during running, biking, dancing,
climbing, snowboarding, basketball, soccer, football, etc.

Calf Raises
Version 1: Standing with Weight
- Apply weight resistance using one of
the following techniques:
 |
- Holding a barbell across your
shoulders
- Wrap a belt around your waist
attached to a floor pulley
- Another form of gym equipment
|
- Stand with the balls of your feet on
a block or step shoulder width apart. Allow your heels to
lower below the balls of your feet.
- Lock your knees and flex your calves
until you're heels are fully raised. Make
sure you don't lean forward. Rise straight up.
- Hold for a second.
- Lower your heels to starting position.
Try one set with your toes pointed straight
ahead, another set with your toes pointed out and another
set with your toes pointed in to work all sides of the entire
gastrocnemius muscle.
Version 2: Standing Endurance Exercise

Seated Calf Raises (using leg press equipment)
Main Target: Calf muscles
This exercise is easy on the back.
- Lie in the leg press machine. With
knees slightly bent rest the balls of your feet against
the platform near the edge with the arches and heels of
your feet hanging off the edge of the platform.
- Allow your heels to extend as far as
possible with the balls of your feet remaining stationary.
This helps you achieve a maximum range of motion.
- Raise the weight by extending the balls
of your feet.
- Pause.
- Lower the weight to the starting position.
|
 
|
|

Seated Calf Raises
Same as seated calf raises using leg press
equipment only with the weight resting on the tops of your
knees and thighs.
This is another method that is easy on your
back.

Martial Art Kicking Exercises Using the
Floor Pulley
Main target: hip and thigh.

resistance. simply practice kicking by itself. 3 to 4
sets of 10 to 20 reps each. Once you can accomplish 20 reps
with ease, then start to use the floor pulley to add resistanceÉ
- Fasten
a strap around one of your ankles and attach it to a floor
pulley.
- Place
your free foot 2.5 to 3 feet from the pulley and face away
from the weight stack.
- Grasp
a sturdy vertical pole for stability.
- Start
with your bound foot behind you.
- Option
1: Complete a front kick by quickly raising your knee
high, then extending your lower leg as high as possible
in front of you, pointing your toes. Return foot to starting
position and repeat.
- Option
2: Complete a round-house kick. We recommend you get
martial arts training for this particular kick to avoid
injury due to improper technique. A brief description can
be found under self-defense.
- Option
3: Complete a sidekick. Once again, training is recommended.
A brief description is available under self-defense.
- For
either option do 3 to 4 sets of 10 to 12 reps each.

Hamstring Stretch
It's more effective to stretch one

leg up.

your right thigh.
- Slowly straighten
your right leg keeping your foot flexed at a 90û angle to
your leg.

are rather flexible and you need more of a challenge, wrap
a towel around the ball of your foot, and gently pull it
down with your hands.
- Feel it in the back
of your raised leg.
|

|
|

Option 2

with your left leg straight and your right leg bent so your
right foot is resting against your inner thigh.

- If you can, bend
your torso at the hips toward your feet taking hold of your
raised leg with your hands.
- Feel the stretch
in the back of the raised thigh.
- Repeat with your
other leg.
Note: The hamstrings can cause
great pain and injury if not thoroughly stretched, so you
might want to hold these stretches for up to 1.5 minutes.
For increased effectiveness, while bent forward in the stretching
position with your extended leg slightly bent, tighten all
of the muscles of the upper leg for four to five seconds.
Then relax the leg. As you relax, you should be able to move
farther into the stretch. Try this technique several times
with each leg. This technique of contracting and relaxing
helps with other stretches as well.

- Humans have exceptionally large calf muscles
due to our upward stance, which requires the entire body weight
to be supported on two limbs instead of 4, like most other animals.
- The lateral head of the gastrocnemius often
contains a small bean-shaped bone.
- A single muscle cell of the sartorius muscle
in the thigh can be more than 12 inches long.
- You take 5 million steps per year.
- You have all the muscle fibers you will ever
have at birth. Once damaged they can't be replaced.
- Arnold Shwarzenaeger has just about as many
muscle fibers as you do. They're just thicker.
- There are more than 600 voluntary muscles
in the body.
- If all your muscles could pull in one direction
you could create a force of 25 tons.
- Muscles account of 40% of your body weight.
