A night has passed.
The three have already undergone the evolutionary transformation by Wang Ye.
Due to the significant enhancement of their physical fitness,
they now find even walking quite challenging.
Walking may seem like just moving steps,
but it actually involves a lot of muscle movements.
A simple step requires switching between the main leg and the power leg,
stabilizing the center of the knee and ankle joints,
and the coordination of the core muscle group and arm swings to maintain balance, all of which involve extremely complex muscle movements.
When the heel touches the ground, it decelerates the forward motion of the lower limb, setting the foot in the support position. The muscles involved include the quadriceps, psoas major, and multifidus muscles.
When the foot is placed flat, the involved muscles are the gluteus maximus, hamstrings, and tibialis anterior. Subsequently, when standing, almost all the leg muscles are in a state of isometric contraction.
