关于运动和健康，一般的共识是有氧和举重增肌相结合。但是又有说法，太多有氧不利于增肌。问题是，多少有氧是“太多”呢？在网上查了一下为什么有氧会不利于增肌，没有找到这方面的科学文献，只在论坛里有些讨论，比如reddit：
“If you want to put on muscle mass then you gotta be at a calorie surplus (you can still get stronger at a calorie deficit but it's slower and you won't put on much muscle mass). If you're doing cardio that much then you're probably burning a lot of calories from it. If you account for the calories you burn from cardio and you're still eating at a surplus, it's all good, you'll gain muscle mass. You might be at a deficit if you account for your cardio which would make it very hard to put on muscle mass”
不清楚这些人的背景，所以不能想当然。这个说法的根据在于calorie surplus有助于增肌，而有氧会消耗很多卡路里。想听听大拿们和专业人士的看法，这个说法靠谱吗？如果是calorie surplus的问题，那可以在做有氧的时候多吃点补充上来。
另外，我在想，也不一定要当天补吧？因为人体本身就是“蓄能器”，有很多存储。即便是马上吃东西，消化吸收也需要时间，恐怕赶不上趟了吧？平时，或者做有氧的前一天就要有些surplus？
