4 days/week (more volume, still beginner-friendly): Upper/Lower split (Mon Upper, Tue Lower, Thu Upper, Fri Lower). Great when full-body sessions get too long. Target ~10–14 hard sets per muscle. #WorkoutSplit #Hypertrophy Fast rules that work: Train each muscle about 2x/week. Don’t stack full-body days back-to-back; leave at least 1 rest day. #Recovery Days per week matters less than weekly hard sets. Add a day only if you recover well, stay consistent, and need more weekly sets.
