When a muscle contracts the length can either change or stay the same. If the muscle length remains the same it is known as an isometric contraction, an example exercise is holding the plank. Whereas if the muscle length changes it is known as an isotonic contraction, an example exercise is performing a bicep curl. An isotonic contraction involves two phases; the shortening phase (i.e. the up phase of a bicep curl) which is called a concentric contraction and the second phase is the lengthening phase which is known as an eccentric contraction (i.e. the lowering phase of a bicep curl).
