8 Weeks, 4x per week
A 4-day upper/lower split for beginners stepping up from full-body and for early intermediates.
Two upper days (one barbell-strength, one dumbbell-hypertrophy) and two lower days (squat-focused Legs A, hinge-focused Legs B), trained Mon/Tue/Thu/Fri so every muscle is hit twice a week with a rest day midweek.
Progress: drive the working rep range on each lift and add weight when you top it.
Step up from Full Body Barbell, then move toward PPLUL or PPL when you want more volume.
