What is isotonic and isometric?

In summary, skeletal muscle contractions are either isometric, in which the muscle does not change its length, or isotonic, in which the muscle changes its length without increasing tension. Once the load is exceeded, contraction can then be used to shorten the muscle and move the load.

Similarly, it is asked, how do isotonic and isometric differ?

An isometric contraction is when the joint angle and muscle length do not change during contraction(compared to concentric or eccentric contractions, called dynamic/isotonic movements). A perfect example of an isometric contraction is a 'wall sit' exercise.
