The changes in the muscle tones make us able to move. So contractions will follow depending what activity we are engaged on, as a continous and passive partial contraction of muscles change following changes in direction.
Muscle tones have contractions that do not produce enough tension to move, buy they keep it tense and firm.
Thererefore the tension is balanced and resting muscle tone balances bones and joints.
