Great ab exercises; V-snaps



  • V-snaps; lie on your back with your arms stretched out above your head. Squeeze your abs together to lift your legs and torso off the ground simultaneously, so that from side on your body makes a V shape. Slap your hands on the ground when your body and legs are in the air (making the V shape), then return to the starting point. Alternatively, you can reach for your toes in stead of slapping the ground with your hands, if this is too hard.

Lymphatic and Immune System

The immune system has a large array of tools at its disposal in the fight against infection and disease. The skin is the first mechanical defence against foreign substances such as bacteria, radiation and harmful chemicals. The tear glands in your eyes contain antibacterial enzymes, and the saliva which is produced in your mouth contains antibacterial agents as well; both serving to catch and destroy foriegn particles. To protect against airborn assaults, nostril hair, mucus and cilia in the lining of the nose and airways catch and dispose of dust, microrganisms and debris. Further into the body, in the digestive system, very strong acids, enzymes and juices are produced in the stomach and intestines that attack any foreign invaders that have managed to slip past the body's outer defences.

However, this only accounts for the systems protecting and fighting against infection/disease from the outside. What about the ones fighting against infection, cancer cells and allergies that have already invaded the body?

This is where the lymphatic system is integral. Once the white blood cells (formed in bone marrow) have fought and destroyed the invading microbes (whether it be infection, an allegic reaction etc.), it's the lymphatic glands and ducts that transport the toxic waste and by products out of the body (kind of like a sewerage system in a house). Lymphatic glands are concentrated behind the ears, in the arm pits, down along the spine and in the groin area. The amazing thing is that, unlike the blood being pumped by the heart, the lymphatic fluid relies on muscle contraction and gravity to propell it through the body. Obviously this creates some problems: especailly in sedentary individuals!

This fluid carrying toxic waste out of the body can and will stay stagnant in the body unless, either by the muscles around it or gravity carrying it, it finds its way to the subclavian veins and from there is transported to the urinary system, and subsequently is ejected from the body in the form of urine or feces. This is one of the reasons why sedentary people are more likely to get sick-they do not move enough so their muscles dont compress on the lymph nodes-therefore this toxic fluid stays around and is not passed from the body!

I have heard of a study where they found that orchastra conductors as a profession had the lowest percentage of breast cancer cases compared to any other job! They explained that because a conductor is always waving their arms above their head, muscle contraction and gravity combined effectively flushed the arms and chest of any toxicity-hence the lower case of cancer.

Something to think about when you're next reaching for the corn chips whilst watching TV on the couch...

Systems of the body


The different systems of the body, broken down...I'll expand on these individually soon

Skeletal-bones
Muscular-muscles
Cardio Vascular-heart and blood vessles
Respiratory-lungs and airways
Urinary-bladder etc
Reproductive-sex organs
Endocrine-hormone systems
Nervous-nerves, brain, spinal cord
Lymphatic (immune)-drainage of waste products out of the body
Digestive-food
Integumentary-skin, nails, hair

Exercise of the week: bent over rows


Great for targeting the rhomboids, lats and rear deltoids, this is an excellent exercise for building up/toning the back muscles, whilst also helping your posture. A lot of the activities we do in day to day life is with our hands in front of us ie. pushing shopping trolley, driving etc. This can lead to very strong, over active chest muscles (pec major). Hence people who walk around with shoulders slumped forward in a slight hump back of notra damus look. Targeting the back muscles will counteract this, balancing the body: bent over row-see above.
With a barbell, bent over 45' at hips, keeping back in natural curves, bring weight up to your navel whilst squeezing your shoulder blades together tight. Engage your core the whole time.


Some tips for healthy eating...


Struggling to keep your eating habits under control? Try these helpful tips.


  • Start with a good breakfast; this will kick start your metabolism

  • Eat more meals per day but cut back on the amount of food at each meal (say 6 smaller meals in stead of 3 larger ones), as this will keep your metabolism working for longer

  • Drinking 1-2 L of water each day will also help. A good way to do this is have a jug of water on the bench/at work and fill up a glass each time you walk past

  • Don't skip meals-starving yourself will not help

  • Try to make your own lunch at home to take to work as much as possible: take a shopping list to supermarket and buy all necessary ingreadients there, make lunch the night before

  • Cut back on soft drinks, or anything else full of sugar

  • Stay away from processed foods and high GI snacks-the more natural the food, the better

And remember, a balanced diet that you can actually stick to is a much better option to fad diets!!

Lower back pain


One of the causes of lower back pain is weak core muscles. The lumbar spine in supported by the core muscles around it, consisting of the abdominal muscles, lower back muscles and pelvic floor muscles. These muscles stabilise and support: therefore if they are not functioning properly there is a high chance of lower back pain, especially in runners. If you dont have a disc bulge but have chronic lower back pain, the chances are you have a weak core which needs strengthening. Strengthening your core can alleviate symptoms and help to prevent any forther damage to your lower back. Another cause is hypertonicity (tightness) of the hamstring muscle group and the hip flexors (front of the hip), so stretching them on a regular basis can be beneficial.
