The 3-Day Split: How to Build the Perfect ABC Routine for Hypertrophy

The ABC split divides the body across three days: A (chest, shoulders, triceps), B (back, biceps) and C (full legs). It's the most popular structure in commercial gyms — and the most sabotaged by people who build it wrong.

When the ABC makes sense

If you train 3 to 6 times per week and you're past the beginner phase, the ABC delivers concentrated volume per session with solid local recovery. Training 3x/week runs the cycle once; 6x/week runs it twice — frequency 2, which the literature points to as the sweet spot for most lifters.

The complete program

Day A — Push: bench press 4x6-8; incline dumbbell press 3x8-10; standing overhead press 3x8; lateral raise 3x12-15; cable pushdown 3x10-12; overhead extension 2x12. Day B — Pull: pull-ups or pulldown 4x6-10; bent-over row 4x8; seated cable row 3x10; face pull 3x15; barbell curl 3x10; hammer curl 2x12. Day C — Legs: back squat 4x6-8; leg press 3x10; Romanian deadlift 3x8-10; leg extension 2x12-15; leg curl 3x10-12; standing calf raise 4x12-15.

The mistakes I see every night

• The ghost leg day. Skipping legs isn't a strategy, it's a confession.
• Ego volume on day A. Seven chest exercises and two for triceps isn't a workout, it's a tribute.
• Zero progression. The program can be perfect; without progressive overload, it's just paper.
• Random rest. 2-3 minutes on heavy compounds. The timer is not a suggestion.

ABC or full-body?

Depends on your schedule. If life is unpredictable, full-body forgives absences. If you show up 5-6 times a week without fail, the ABC concentrates stimulus and recovery. Both work. What doesn't work is switching splits every two weeks chasing a shortcut that doesn't exist.

Choose. Execute for 12 weeks. Log everything. Then tell me if you really needed another program.
