then why not train legs everyday and everything else secondary.
(the most pounds lifted) is the true measure of a workout
if you train legs everyday you quickly become humbeld as to find your (true most pounds lifted in a workout) on a daily basis average
you may start out monday strong hittin legs then bis tris , but tuesday hitten legs then chest maybe weaker....but maybe stronger by friday
no point in just focusing a day on arms if the purpose is to grow overall disregarding proportions. youll never lift the amount of pounds with your arms as you can on your legs, its pointless to say youve have an ultimate upper body workout because the poundages simply dont compare to legs
bottom line if people hit legs everyday then you would be forced to develop a true science of eating as how to improve daily leg training because it is only the true measureable capacity
