I am currently training 3x per week, full body workouts (classic HST). The problem is that I don't feel (even slightly) sore after my workout. I have completed the 15's phase and I am in my 10's now, however I have yet to experience DOMS. Maybe it's too soon (and I know DOMS is not necessary for muscle growth), but I am thinking of switching to training 6x per week for my next cycle in order to get more volume in. Since I cannot train twice a day, there are really 2 options: A) Train 6x a week, using an upper body/lower body split (or any other 2-way split). Each body part gets hit 3 times a week and each exercise comprises, say, 4 sets. B) Train 6x a week, full body workouts. Each body part gets hit 6 times a week but each exercise comprises, say, 2 sets only. Which approach do you think would be more beneficial for muscle growth and why? Any help would be greatly appreciated, I am looking forward to hearing your insights.Thanks.
