Arnold Split
Chest & back. Shoulders & arms. Legs. Run twice through, six days a week, the golden-era way.
The Arnold split, named for how Schwarzenegger trained through his Mr. Olympia years, cycles three sessions twice each week: chest and back together, shoulders and arms together, then legs. Pairing antagonists (chest with back, biceps with triceps) lets you superset opposing movements. One muscle rests while the other works, so you get more done without losing quality.
It delivers 2× weekly frequency like PPL but concentrates upper-body volume even harder, which is why physique-focused lifters like it and why it's so demanding. Six days a week with paired muscle groups is an advanced commitment. Recovery, sleep, and food all have to keep up.
The week at a glance
Who this split is for
- Advanced lifters chasing maximum hypertrophy
- Fans of antagonist supersets and high-density sessions
- Physique athletes with 6 reliable training days
- Lifters whose upper body responds to high volume
The workout plan
Day 1 & 4: Chest + Back
Pecs and lats, supersetted- Bench press ss. wide-grip pull-up4 × 6-10
- Incline dumbbell press ss. barbell row4 × 8-12
- Dumbbell fly ss. seated cable row3 × 10-12
- Dip ss. straight-arm pulldown3 × 10-15
Day 2 & 5: Shoulders + Arms
Delts, biceps, triceps- Overhead press4 × 6-10
- Lateral raise4 × 12-15
- Rear delt fly3 × 12-15
- Barbell curl ss. skullcrusher4 × 8-12
- Incline curl ss. overhead extension3 × 10-12
Day 3 & 6: Legs
Quads, hamstrings, glutes, calves- Back squat4 × 6-10
- Romanian deadlift4 × 8-10
- Leg press3 × 10-12
- Leg curl3 × 10-15
- Standing calf raise5 × 10-15
“ss.” means superset. Rest 2 to 3 minutes on compound lifts and 60 to 90 seconds on isolation work. Take most sets 1 to 3 reps short of failure.
Strengths
- 2× weekly frequency with serious upper-body volume
- Antagonist supersets make long sessions time-efficient
- Chest/back days are legendarily productive
- Proven at the highest level of bodybuilding
Trade-offs
- Six days a week, so recovery has to be a priority
- Volume is too high for most natural intermediates
- Supersets need two stations, which is hard in a busy gym
- Legs get the same two slots as on PPL despite the bigger total load
Vora tracks the strain cost of Arnold-split volume against your HRV and sleep. When recovery debt builds for two or more days, it converts the next session to a lighter pump day so the week stays manageable.
Frequently asked questions
What is the Arnold split?
A six-day bodybuilding split that repeats three workouts twice weekly: chest + back, shoulders + arms, and legs. It was popularized by Arnold Schwarzenegger's golden-era training, built around antagonist pairings and high volume.
Arnold split vs PPL: what's the difference?
Both are six days with 2× frequency. PPL groups by movement (push/pull/legs); the Arnold split pairs antagonists (chest WITH back) which enables supersets and an extra dedicated arm/shoulder day. Arnold splits skew harder toward upper-body physique work; PPL balances strength and size more evenly.
Is the Arnold split good for natural lifters?
Only for advanced naturals with excellent recovery. The volume that suited golden-era pros exceeds what most naturals adapt to. A volume-trimmed version, or PPL with an arm-focus day, gets most people the same result with less recovery risk.
Can I do the Arnold split 3 days a week?
Yes. Run one cycle weekly (chest/back, shoulders/arms, legs) with rest days between. Each muscle then gets trained once a week, so push each session's volume a bit higher, or alternate with a second cycle over two weeks.

Bro Split
One muscle group per day, trained hard once a week. An old-school split that still works, with some caveats.
Push Pull Legs
The most popular split in lifting: push muscles, pull muscles, then legs. Scales from 3 to 6 days.
5-Day Split
Five days of focused volume. The hybrid structure that beats the classic bro split.
