There was one exception.
That was Yao Ming.
The Changsha Men's Basketball Asia Championship in 2015 kicked off at the end of September, with Yao Ming not expected to return to the United States until mid-October.
Before training camp began, players still enjoyed their free personal time.
However, some with proactive tendencies would actively seek opportunities for improvement.
For instance, Nikola Jokić spent this past summer in the United States participating in Saint Babara's "Soul Leap" special training camp.
It's a camp specifically devised for elite athletes, emphasizing recovery, training, and targeted enhancement.
The focus is on technology, effective training, and systematic nutritional recovery.
Jokić temporarily set aside his beloved horse racing and spent the entire summer in the United States to boost his physical condition, eventually walking into Yu Fei's training camp like a brand-new human being.
"Nikola, what brings you here?"
