The Arnold Split: 6-Day Workout Program (Full Guide)

The Arnold split is named after Arnold Schwarzenegger, who used a variation of this program during his competitive bodybuilding career in the 1970s. It is a 6-day program that pairs chest with back, shoulders with arms, and dedicates two full days to legs. The pairing of antagonist muscle groups (chest/back, biceps/triceps) allows for higher training frequency and significant pump work within each session.

What Is the Arnold Split?

The Arnold split is a 6-day training program that groups muscles as follows:

- **Day 1 & 4:** Chest + Back - **Day 2 & 5:** Shoulders + Arms (biceps + triceps) - **Day 3 & 6:** Legs

Each muscle group is trained twice per week. The distinctive feature is chest and back pairing — training antagonist muscles in the same session allows for more total volume per session without excessive fatigue on any single muscle group, and the antagonist relationship means training one muscle while the other recovers.

The Full 6-Day Arnold Split Program

Day 1 & Day 4 — Chest + Back

| Exercise | Sets | Reps | Rest | |---|---|---|---| | Barbell Bench Press | 4 | 6–10 | 2–3 min | | Wide-Grip Pull-Up | 4 | 6–10 | 2–3 min | | Incline Dumbbell Press | 3 | 8–12 | 90 sec | | Cable Row | 3 | 10–12 | 90 sec | | Cable Fly | 3 | 12–15 | 60 sec | | Lat Pulldown | 3 | 10–12 | 90 sec | | Dumbbell Pullover | 3 | 12–15 | 60 sec | | Face Pull | 3 | 15–20 | 60 sec |

*Superset chest and back exercises where possible (e.g., bench press, then immediately pull-ups, then rest). This is the traditional Arnold approach.*

Day 2 & Day 5 — Shoulders + Arms

| Exercise | Sets | Reps | Rest | |---|---|---|---| | Overhead Press (Barbell or DB) | 4 | 6–10 | 2–3 min | | Arnold Press | 4 | 8–12 | 90 sec | | Lateral Raise | 4 | 15–20 | 60 sec | | Rear Delt Fly | 3 | 15–20 | 60 sec | | Barbell Curl | 3 | 8–12 | 90 sec | | Incline Dumbbell Curl | 3 | 10–12 | 60 sec | | Skull Crusher | 3 | 10–12 | 90 sec | | Tricep Pushdown | 3 | 12–15 | 60 sec | | Cable Overhead Tricep Extension | 3 | 12–15 | 60 sec |

Day 3 & Day 6 — Legs

| Exercise | Sets | Reps | Rest | |---|---|---|---| | Back Squat | 4 | 6–10 | 3 min | | Leg Press | 4 | 10–15 | 2 min | | Romanian Deadlift | 4 | 8–12 | 2 min | | Leg Curl | 3 | 12–15 | 90 sec | | Leg Extension | 3 | 12–15 | 90 sec | | Hip Thrust | 3 | 12–15 | 90 sec | | Standing Calf Raise | 4 | 15–20 | 60 sec | | Seated Calf Raise | 3 | 20–25 | 60 sec |

**Weekly schedule:** - Monday: Chest + Back - Tuesday: Shoulders + Arms - Wednesday: Legs - Thursday: Chest + Back - Friday: Shoulders + Arms - Saturday: Legs - Sunday: Rest

Arnold Split vs PPL: Which Is Better?

| Factor | Arnold Split | Push Pull Legs | |---|---|---| | Days per week | 6 | 6 | | Chest frequency | 2x/week | 2x/week | | Back frequency | 2x/week | 2x/week | | Shoulder frequency | 2x/week | 2x/week | | Arms frequency | 2x/week | 2x/week | | Legs frequency | 2x/week | 2x/week | | Session length | 60–90 min | 60–75 min | | Antagonist pairing | Yes (chest/back) | No | | Volume per session | High | Moderate-high | | Best for | Intermediate-Advanced | Intermediate-Advanced | | Chest-back pump | Excellent | Good |

Both programs train each muscle group twice weekly. The key difference is session organization: Arnold split sessions are longer (especially chest/back days with combined volume) while PPL sessions are more focused on one movement pattern. Neither is strictly superior — choose based on preference and recovery capacity.

Who Should Use the Arnold Split?

**Best for:** - Intermediate to advanced lifters with 2+ years of consistent training - Lifters who enjoy longer, higher-volume sessions - Anyone who wants a structured bodybuilding program with classic roots - Lifters who like training antagonist muscles in the same session

**Not recommended for:** - Beginners (volume is excessive; start with full body or upper/lower) - Lifters with limited recovery (poor sleep, high stress, large calorie deficit) - Anyone who cannot commit to 5–6 days per week consistently

The chest/back combination creates very long sessions (75–90 minutes), which requires discipline and adequate gym time.

4-Day Arnold Split Modification

If 6 days is not feasible, you can run a 4-day version:

| Day | Session | |---|---| | Monday | Chest + Back | | Tuesday | Shoulders + Arms | | Thursday | Chest + Back | | Friday | Legs |

This reduces overall volume and drops one leg session per week, but preserves the characteristic chest/back pairing and keeps each muscle at minimum 1x frequency. Add the second leg session back if a fifth day becomes available.

Progressive Overload in the Arnold Split

With high session volume across 6 days, progression must be managed carefully:

- **Primary compound lifts:** Add weight when you hit the top of your rep range across all sets (double progression) - **Accessory work:** Use rep progression — fill out your rep range, then add load - **Deload every 6–8 weeks:** Reduce volume by 40–50% for one week

The risk with the Arnold split is ego loading — pushing weight too fast on long sessions leads to form breakdown and injury. Prioritize quality over load, especially on the accessory work.

Frequently Asked Questions

**Did Arnold actually train this way?** Versions of this split appear in Arnold's early writings and interviews about his Golden Era training. The specific program as commonly presented is a structured interpretation — actual training logs from that era are incomplete. Regardless of exact origin, the structure is sound and the program works.

**Is the Arnold split good for beginners?** No. The volume per session (especially chest/back days) is far too high for beginners to recover from. Run a beginner program (Starting Strength, StrongLifts, GZCLP) for at least a year before attempting a 6-day program.

**Can I gain strength on the Arnold split?** Yes, though it is primarily a hypertrophy program. Keep the main compound lifts (bench, squat, deadlift, overhead press) in the lower rep ranges (5–8 reps) to build both strength and size.
