That is false advertising. As we often assert, the only way to be lean is through appropriate nutrition. Improving strength, agility, endurance, etc. require putting in serious exertion which, it seems, most people do not have the heart for. It is not fun. Yes, many Americans eat too much. "Healthy" or not, just too much of it.
I think that I have confessed in the past that the real reasons I appear so disciplined with daily early AM workouts are 1: to get my head in a good place for the day, 2: to fend off age and loss of function, and 3: to not look like I am over the hill. I am fortunate in a way that food is not a big mptivator for me. I like fine food but it doesn't do much for my soul.
Still, these are excellent strength workouts for men, women, and all of the other "genders". I prefer pull-ups to pull-downs, even if assisted, but that's just my preference.
