What is Isotonic Exercise?

Isotonic exercise is a very popular form of muscle-strengthening.

Isotonic exercise can be carried out either with:

In both forms exercises are carried out against a fixed resistance.

As each muscle moves through its complete range, isotonic contraction creates tension with maximum effort at the beginning and end of each exercise.
