  1. This is a great question because once answered and understood it reveals the truth and puts to rest all the flase ad’s and hype selling non-weight training methods. These so called ancient chinese methods being hawked by money hungry internet guru’s claim they can make you as strong and muscular as the guy training with weights. HOG WASH!

    BASIC ANATOMY
    The inner workings of the human body are both refined and complex. Unless you are a scientist it is difficult to grasp the total principals. Yet you must have a basic understanding of the simpler principals in order to reach your individual fitness goals.

    WORKING SYSTEMS OF THE HUMAN BODY!

    BONES are the framework of the body.

    MUSCLES control all movement in the human body, and make up 40-50% of the body’s weight.

    CONNECTIVE TISSUE of various types, including tendons and ligaments, connects muscles to bones and tethers and cushions organs and various body parts.

    BRAIN and nervous system initiate and guide all the body’s activities.

    DIGESTIVE SYSTEM changes food into energy.

    HEART, BLOOD VESSELS and LUNGS provide oxygen and nutrients to the muscle and other cells to sustain them so they can perform their functions.

    Of these six systems I mentioned, two of them - muscles and connective tissue - are of most interest to the weight trainer.

    MUSCLE CELLS

    Muscles are the flesh or meat of the body. Muscle cells are in the form of fibers-long, cylindrical cells bound together by a membrane in bundles. Muscles fibers are much like a (bridge cable) with bundles of wire wrapped and running along inside.
    Inside the muscle fibers are myofibrils.

    WHAT HAPPENS INSIDE THE MUSCLES WITH WEIGHT TRAINING?

    1, The connecting elements-the actin and myosin myofilaments-increase in size (hypertrophy).

    2,The myofibrils increase in size.

    3, The motor nerves and the motor end plates that stimulate muscles may increase in number.

    4, The amount of connective tissue within muscle cells may increase.

    5, The amount of blood circulation to and through the muscles increases and the number of capillaries within the fiber may increase.

    HOW MUSCLES GROW IN RESPONSE TO THE STRESS OF WEIGHT TRAINING!

    1, The first four types of growth listed above, hypertrophy or increase in size, are associated with strength training. Low repetitions, heavy weights.

    2, The fifth type of growth, vascularization or increase in blood supply and capillaries is most enhanced by endurance training. High repetitions, light weights.

    THE OVERLOAD PRINCIPAL

    It’s a fact that if you want to increase strength or endurance, or better yet both, you must overload the muscle.

    To “overload” a muscle means simply that you stress the muscle in intensity or time duration beyond the demands of the previous workout. This workout is then followed by a rest period during which the muscle rebuilds with greater strength and endurance.

    The muscle cells are programmed to rebuild stronger so they can handle greater stress the next time.

    This is by far the most important, yet most overlooked principal in the art of bodybuilding. Everybody is looking for the magic powder or pill that will build bigger, stronger muscles. It’s PROPER training that grows bigger muscles. The food and sleep are what allow the growth to happen. Under eating and minimal sleeping habits stunt growth.

    ADDITIONAL BENEFITS OF WEIGHT TRAINING!

    1, Improve your overall health.

    2, Makes you feel better and gives you energy.

    3, Helps you to maintain a desired weight.

    4, Makes you physically look better.

    5, Will help you prevent or rehabilitate injuries.

    6, Improves balance and coordination.

    7, Helps you develop greater stamina and speed.

    8, Improves overall circulation.

    9, Improves internal waste elimination.

    10, Helps flush lactic acids and toxins out of the system.

    11, Improves digestion.

    CONCLUSSION

    Pumping away with push-ups and one legged squats are a great way of conditioning the body and getting fit, but in the end you’ll look like a tennis player. If you want larger, shapley, stronger, powerful looking muscles you MUST TRAIN WITH WEIGHTS, PERIOD.

  2. This is telling the truth.
    I have been weight-trainning for years,and I have tried different ways of trainning and found different results. with different ways of doing the exercise.
    i definitely agree to this testimonial.
