A secondary argument is it's time efficient, results come fast and you get the most health and strength benefits with the least amount of time investment compared to say low impact aerobic regiment such as biking. I've done both and have to say I agree that starting strength method is optimal for busy professionals. Also lifting heavy weights is strength training and cardio training. You can't lift heavy weights without getting a cardio workout at the same time.
