Dongfang Yu gave her a sidelong glance, "Even if you exercise for two hours every day, you won't be able to gain much muscle. I ask you to stretch just to relax the muscles."
"Why can't I gain muscle?"
"Muscle isn't that easy to build, diet and hormones are very important. Unless you are a man, men can easily gain muscle; without professional training, it's difficult for women."
"Really?" Hai Xiaotang didn't believe it and even went to specially brush up on this knowledge.
Indeed, just as Dongfang Yu said, it's hard for women to gain muscle, but gaining fat is quite easy...
No wonder men can eat a lot and not easily gain weight, because they easily gain muscle, which consumes calories.
So what they eat is consumed by the muscles...
This is also why Dongfang Yu doesn't allow Hai Xiaotang to run for too long, as it would consume the muscle that women already have so little of!
Hai Xiaotang suddenly envied men, who almost never gain weight with a normal diet.
