@gina7arth Some of it, I'm sure, is people who don't mind being top heavy (young guys especially don't seem to mind this), but for most it is a volume thing. For example: If I'm forced to do a single KB workout (which sometimes life demands if I'm working out on a job site or something) I'll do a 20 kg, 30-40 reps of goblet squat, sumo squat, single arm dead lift, alternating lunges, and swings, 50 pushups, 50 rows, 30 sumo high pulls, and 20 to 30 clean and press, along with situps, reverse situps, twists, etc. So at the end, out of 9 main exercises, five are lower body focused, two are full body complexes, only two are upper body focused, and basically everything works the core to some degree.
