After all, martial arts cultivation involves two main aspects: channeling energy and coordinating the body's movements and steps.
The benefits of a powerful physique, besides enhanced recovery and resilience, are more evident in the strength of one's meridians. Strong and resilient meridians can withstand increased frequency and volume of Spiritual Energy.
To put it simply, even when training the same exercises, Tang Tianyu can train five hundred times due to the strength of his meridians, while Yang Fan, after two hundred times, would experience discomfort in his meridians, triggering the body's protective mechanism resulting in spasms, convulsions, and blockage.
Some with weaker bodies or narrower meridians can't even reach two hundred repetitions.
This is why it's often said that martial arts cultivation is a game for noble families.
