Im a noob, and I was just wondering, why do people train legs(like all the squats and deadlifts and hamstring and quad and calve exercises)? Because I am thinking of not training them because I am not particularly looking to build my legs??(I am not playing a sport competitively)…
also one more question, how long is a good workout for a full body workout?(assuming I go 3 times a week). Is 35-40 minutes too short?(this time is not including abs, which i do at home)
