Yes it's a lot more than what people "achieve", but it's the amount that people should be doing. Doing sport is not a chore that must be "achieved", it's a pleasant and relaxing activity that most people should be enjoying. The entire discourse around sport and physical activity is fucked up in the first place. When you hear public health official advising to do sport, they are almost apologising for it.
Counting kcal per hour of sport like that doesn't make any sense. 300kcal is 1h of brisk walking (non-sedentary people do it as part of their daily life, and probably don't count it toward their physical activity). It's also 1h of weight lifting, which most people would probably consider intensive sport. OTOH it's only 30min of jogging, which is a utterly trivial amount of sport for any healthy person. Those are rough approximations obviously.
After clicking the "reply" button of this post, I'm leaving for training with my sports club. 30min brisk walk each way to get there, and 1.5h of sport that is estimmated to burn 500kcal/h. Burning calories is trivial for active people.
