I once jointed in a YMCA Karate class. The instructor always started his class with sit up, push up, running around the room, .... I asked that instructor, "Why do we have to do this? I can do this at home." He said, "Most people don't do this at home." I then found a basic difference in training.
Some people
- come to school to "learn" and go home to "train".
- come to school to "train" and go home to "rest".
When
- someone asks, "How many times do you train weekly?"
- another person asks, "How many times do you train daily?"
These 2 persons definitely don't belong to the same page.
