So you are starting body building, but what exactly is it? When starting anything in life it's always important to understand exactly what it is, so that you can explain to at least yourself what you are doing.
Body building can be defined as basically where the body is made to work against gravity and in that process the body adapts, becomes stronger and forms more muscular shape that is a body builder.
In my opinion if you have ever wanted to do some exercise you are in fact a body builder.
For in the stricter sense we think only of competition body builders.
However, if you think about it, if your lifting weights and are running on a treadmill, are you not trying to shape, maintain or strengthen your body? Hence we're all body builders.
Now weight training is a form of exercise which subjects the body to an increase in the amount of resistance.
This is in the form of weights or weight machines, or even your own body weight.
When you weight train it increases the size of the muscles, and once our bodies adapt to the increase in load, the size of the muscles increase, which then leads to more strength and a better state of fitness.
When we participate in body building or resistance training our muscles (composed of fibers) tire out.
This then leads to recruiting new muscle fibers, or muscle gain.
This only happens however if the weight is heavy enough and that the any amount of weight can only be lifted to failure or to the prescribed number of repetitions.
One more point, it you think you building your body you train, well think again.
Your body repairs itself and gets bigger whilst you rest, so get plenty of rest or sleep when you're starting body building.
