So what you are speaking of with "newb gains" is literally your body reaching a new homeostasis point. In which I agree to take advantage of this period of your body reaching this new homeostasis point("plateau"), but I have to disagree with staying away from "bodybuilding workouts". I always get confused when people call them that because I'm a natural bodybuilding and I squat very heavy, deadlift, and bench sometimes(although I do mainly do dumbbells admittedly). So am I a bodybuilder doing "strength workouts". No I am not, I am taking advantage of strength gains and using them on my "bodybuilding workouts". I am sorry but the majority of people would rather have greater muscle mass gains than optimal strength gains. Also, the "newb gains" are a great period to use "bodybuilding type workouts" why would you not want to OPTIMALLY gain muscle mass in the beginning of your training regimen? I am NOT saying at all that strength type workouts do not gain muscle, because obviously that is not the case but strength workouts are not in any way more optimal than bodybuilding type workouts, and honestly without a competent instructor(which are becoming increasingly more difficult to come by) throwing someone who hasn't lifted in awhile into complex movements like squads and dead normally results in bad form, too much weight, and not a complete movement. And yes "bodybuilding workouts" can be done incorrectly as well but they have much less likelyhood of bad injury. Also, I have provided videos with very detailed instructions oh how to optimally do the movement. So no OP I don't think it is more optimal in any way to avoid bodybuilding type workouts, but I do think it is great to do power movements just within your means and couple them with strict form supplementary workouts(make sure you do your power movements with correct form that is crucial to your health)
