How to Choose Your Training Split

One of the most common questions in fitness is which training split to follow. Full body three days a week or push/pull/legs five days? Upper/lower four days or a classic bodybuilding bro split? The answer depends on your schedule, experience level, and goal – not on what works for someone else.

The Core Principle: Frequency and Volume

Every muscle group needs a minimum effective dose of training to grow and a maximum recoverable dose before it becomes counterproductive. Research consistently shows that training each muscle group at least twice per week produces better hypertrophy results than once per week. Your split exists to distribute volume across the week in a way that respects this principle while fitting your life.

Full Body (2-3 Days Per Week)

Every session trains every major muscle group. Works well for beginners building foundational movement quality and for anyone with limited training time. The lower frequency per session means lighter loads on individual muscle groups, but each muscle gets hit multiple times per week.

• Best for: Beginners, people with 2-3 days available, those returning from a break
• Limitation: Session length grows quickly as you advance and need more volume per muscle group

Upper/Lower (4 Days Per Week)

Two upper body days and two lower body days per week. Each muscle group gets trained twice per week with enough volume per session to drive real growth. The most efficient split for intermediate lifters who can commit to four sessions.

• Best for: Intermediate lifters, reliable 4-day schedules, balanced strength and hypertrophy goals
• Limitation: Requires consistent 4-day availability; lower body sessions can be demanding

Push/Pull/Legs (3 or 6 Days Per Week)

Push day: chest, shoulders, triceps. Pull day: back and biceps. Legs: quads, hamstrings, glutes, calves. Run it three days per week and each muscle group gets trained once. Run it six days and each gets trained twice. The three-day version is the most common.

• Best for: Intermediate to advanced lifters, those who enjoy dedicated muscle group sessions, 3-6 day schedules
• Limitation: In the 3-day version each muscle is only trained once per week, which is suboptimal for hypertrophy

5-Day Bodybuilding Split

One muscle group per day: chest, back, legs, shoulders, arms. Maximum volume per muscle group per session. Each muscle is trained once per week with full focus and recovery between sessions.

• Best for: Advanced lifters, those who can train 5 days consistently, dedicated bodybuilding goals
• Limitation: Lower training frequency per muscle group; requires 5 reliable sessions per week

How to Choose

Ask yourself three questions:

1. How many days can I reliably train per week? Be honest. The best split is one you can actually follow. Two reliable days beats five inconsistent ones.
2. How long have I been training? Beginners need movement quality and frequency more than volume. Advanced lifters need volume and specialisation.
3. What is my primary goal? Strength and athletic performance respond well to full body and upper/lower. Bodybuilding aesthetics respond well to splits that allow higher per-muscle volume.

The Honest Answer

For most people, a well-designed 3-4 day program that they follow consistently for a year will produce better results than the "optimal" 6-day program they follow for three months before burning out. Match the split to your life, not to an ideal that does not exist in it.
