I sometimes read claims like “doing strength training for more than [insert small number of times per week] is useless, see scientific evidence”. Another impression is: people doing lots of exercise per week get big muscles. How do these observations relate to reality? What is the fitness production function, or the optimal schedule, if one really wanted to become something like a Schwarzenegger? (I don’t. This is just curiosity.)
