These days fitness pros
Primal Grow Pro, bodybuilding magazines, gyms and even certified personal trainers will tell you the optimal workout, whether for muscle mass or strength training, ranges from 30 minutes to an hour. They'll tell you that you can't lift heavy enough and go any longer than that, and that if you're not exhausted after an hour your weights are too light. They'll tell you that weightlifting for more than an hour produces too much cortisol that destroys your gains.
To begin, I think it's important to understand that the word 'spanking' is a euphemism for violent behavior. Yes, violence. That very thing many spankers will prevent their kids from seeing on TV. With all the fuss being made over the negative influence of children viewing abstract violence on video games, TV, and movies, one might get the impression that fantasy/abstract violence is worse for kids than experiencing the actual thing.
