Isometric contraction occurs when muscle length remains relatively constant as tension is produced. For example, during a biceps curl, holding the dumbbell in a constant/static position rather than actively raising or lowering it is an example of isometric contraction.
Which is the best example of isometric muscle contraction?

What is an example of isotonic muscle contraction?

Is a squat isometric or isotonic?
isotonic exercise
