We can confirm that a person with very toned muscles likely has tightly packed myofibrils.

<h3>What are myofibrils?</h3>

These fibers are the protein filaments that cause contractions in the structure of the muscle. Weight training tones muscles by increasing the number of myofibrils in a sarcomere, thus increasing its capacity to produce force.

Therefore, we can confirm that a person with very toned muscles likely has tightly packed myofibrils.
