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

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.
