Isotonic exercise (or muscle contraction) is when the muscle contracts and shortens giving movement (ie a bicep curl, lifting and lowering weight) Nearly all the training you do is Isotonic the opposite is Isometric, where the muscle contracts but des not shorten, giving no movement. Eg, Weightlifting, Lifting the weight up and down is isotonic Holding the weight still above the head is isometric

Isotonic and Isometric exercise are the two types of the exercises. In Isotonic exercise you do not use the load or weight. You can use the antagonist muscle contractions in Isotonic muscle exercises. In isometric exercises you use the weight or load to develop the muscles. You know the term, metric tone. So in Isometric exercise you lift the weight.
An isometric contraction is when your muscles contract but there is no movement. To do one you just need to apply a force to an immovable object. In the strength training sense it is done typically using a power rack or weight lifting cage. The isometric contraction is done typically at the most difficult point of a isotonic lift and is held for 8-12 seconds at maximum exertion. The support pins of the power rack are set at the desired height and a steel bar is then pushed against them to perform the isometric contraction.
Isokinetic exercise utilizes machines that control the speed of contraction within the range of motion. Isokinetic exercise attempts to combine the best features of both isometrics and weight training.
Isometric exercise will not burn very many calories. While it does burn some, it is a strength training exercise, whereas something like sit ups or running burns calories.
What is isometric exexrcises
An isometric contraction builds tension but there is no joint movement.
A line that is isometric
I think both are same. There is difference between isometric view and isometric drawing that is of size.
For free weight training I would look in to http://www.sparkpeople.com/resource/fitness_articles.asp?id=1033. It is a very informative article that discusses the benefits of weight training and gives you tips on weight training.
