The Complete Guide to Workout Splits (2026)

A workout split is how you organize which muscle groups you train on which days. It determines your training frequency — how often each muscle gets worked — and your recovery structure. The right split maximizes muscle growth while fitting your schedule. The wrong split leads to burnout, missed sessions, or suboptimal results.

The fitness industry loves to debate which split is “best.” The truth: there is no universally superior split. The best split depends on three factors: how many days you can realistically train, your experience level, and your primary goal. This guide covers every major split with clear recommendations for who should use each one. No ambiguity, no “it depends” without actionable guidance.

By the end, you will know exactly which split to use and why. For the research methodology behind these recommendations, see our training methodology.

What Is a Workout Split?

A workout split is your weekly training template. It defines which muscles you train on which days and, by extension, how much rest each muscle group gets before being trained again.

The core trade-off in split design is frequency vs. volume per session. Full body training hits each muscle 3 times per week with moderate volume each session. A bro split hits each muscle once per week with maximum volume that session. Both can work — but one will be better for your specific situation.

Research consensus points to training each muscle 2 times per week as optimal for most people seeking hypertrophy. Splits like Push/Pull/Legs and Upper/Lower achieve this naturally. However, beginners thrive on higher frequency (3x/week full body), and advanced lifters sometimes benefit from lower frequency with higher per-session volume.

The sections below break down each major split, who it's best for, and how to choose.

The 5 Major Workout Splits

Push Pull Legs (PPL)

Structure: Push day (chest, shoulders, triceps) / Pull day (back, biceps, rear delts) / Legs (quads, hamstrings, glutes, calves)

PPL is typically run as a 6-day program — Push, Pull, Legs, Push, Pull, Legs, Rest — giving each muscle group two training sessions per week. It can also be run as 3 days per week (each muscle 1x/week), though this sacrifices the frequency advantage.

Pros: High frequency per muscle (2x/week), logical grouping by movement pattern, excellent for hypertrophy, plenty of room for isolation work. The push/pull organization means muscles are already warm from compound movements when you hit isolation exercises.

Cons: Requires 5-6 days per week for optimal results. High time commitment overall. Can be fatiguing if recovery is not dialed in.

Best for: Intermediate to advanced lifters with 5-6 training days available who prioritize muscle growth. If you have the schedule for it, PPL is one of the most effective splits for hypertrophy.

For complete PPL programs with exercises, sets, reps, and progression, see our best push/pull/legs split guide.

Upper/Lower Split

Structure: Upper body day / Lower body day, alternating. Typically run as 4 days per week: Upper, Lower, Rest, Upper, Lower, Rest, Rest.

Upper/Lower hits each muscle twice per week with only 4 total training days. This makes it the most time-efficient way to achieve optimal training frequency for hypertrophy.

Pros: Achieves 2x/week frequency with only 4 days. Simple structure. Each session covers complementary muscle groups. Great balance of recovery and stimulus.

Cons: Upper days can run long — chest, back, shoulders, biceps, and triceps is a lot to cover. Less isolation time per muscle compared to PPL. Legs only get two exercises per session for many people.

Best for: Intermediates with 4 days available. People who want solid results without living at the gym. Those transitioning from full body who need more volume per muscle group.

For a detailed comparison of Upper/Lower vs. PPL, including when to choose each, see Upper/Lower vs. PPL.

Full Body

Structure: Train all major muscle groups every session. Typically 3 days per week with at least one rest day between sessions.

Full body training is the most research-supported approach for beginners. Each muscle gets trained 3 times per week, which is more than enough stimulus when you are new to lifting and recovery demands are low.

Pros: Highest frequency per muscle at lowest weekly time commitment. Most supported by research for beginners. Simple to program — 5-6 exercises per session covers everything. Skills develop faster with more frequent practice.

Cons: Sessions can be long (60-75 minutes) if you add isolation work. Hard to fit adequate volume for each muscle as you advance. Cumulative fatigue builds across the session.

Best for: Beginners in their first 6-12 months of training. Anyone who can only train 3 days per week. People focused on strength and general fitness rather than pure hypertrophy.

Bro Split (Body Part Split)

Structure: One muscle group per day. Classic example: Chest Monday, Back Tuesday, Shoulders Wednesday, Legs Thursday, Arms Friday.

The bro split trains each muscle once per week with maximum volume in a single session. It was the dominant training approach from the 1980s through 2000s and remains popular in bodybuilding culture.

Pros: Maximum volume per muscle per session. Long recovery between sessions for the same muscle (7 days). Simple “one muscle, one day” structure. Can be effective for advanced lifters who need high per-session volume.

Cons: Each muscle is only trained once per week. Research suggests 2x/week produces more hypertrophy than 1x/week at equal volume. If you miss a day, that muscle goes untrained for 2 weeks. Requires 5 days per week.

Best for: Advanced lifters who respond well to high per-session volume. Bodybuilders in contest prep who need extreme isolation work. People who have already tried PPL or Upper/Lower and want to experiment.

Not recommended for: Beginners or early intermediates. People who frequently miss training days.

Hybrid Splits

Hybrid splits combine elements of the core splits above. Popular examples include:

• Arnold Split: Chest/Back, Shoulders/Arms, Legs — run twice per week (6 days total). Pairs antagonist muscles for supersets and efficiency.
• PHUL (Power Hypertrophy Upper Lower): 4 days per week with 2 power-focused days and 2 hypertrophy-focused days. Combines strength and muscle building.
• PHAT (Power Hypertrophy Adaptive Training): 5 days per week with power upper, power lower, and hypertrophy days. More advanced version of PHUL.

Hybrid splits work well for experienced lifters who understand their recovery capacity and want to customize their training. For most people, sticking with a pure PPL, Upper/Lower, or Full Body split produces equivalent results with less complexity.

How to Choose the Right Split

The following framework gives you a definitive answer based on your situation. No ambiguity — just match your circumstances to the recommendation.

Choose by Days Available

Choose by Experience Level

Choose by Goal

• Muscle building (hypertrophy): PPL or Upper/Lower. The key is 2x/week frequency per muscle with adequate volume.
• Fat loss: Any split works — training split does not directly affect fat loss (calorie deficit does). That said, higher frequency splits burn more total calories through more training days. See our workout splits for fat loss guide.
• Strength: Full Body or Upper/Lower. More practice on compound lifts leads to faster strength gains. PPL spreads compounds across too many days.
• General fitness: Full Body. Most time-efficient, covers all bases, easy to maintain long-term.

How Often Should Each Muscle Be Trained?

The 2016 Schoenfeld meta-analysis — the most cited study on training frequency — found that training each muscle group 2 times per week produced significantly more hypertrophy than training 1 time per week at the same total volume.

This is why PPL (6 days) and Upper/Lower (4 days) are considered optimal for muscle growth: both achieve 2x/week frequency. Full Body (3 days) achieves 3x/week, which is also effective but harder to sustain as volume needs increase.

The bro split's 1x/week frequency can work — especially for advanced lifters with high per-session volume — but is suboptimal for most people. If you currently use a bro split, consider switching to an Upper/Lower or PPL structure.

When to Change Your Split

Do not change your split because you are bored. Consistency compounds. Jumping between splits every few weeks prevents progress on any of them.

Change your split when:

• Your schedule changes. If you go from 6 available days to 4, switch from PPL to Upper/Lower. If you drop to 3 days, switch to Full Body.
• You plateau for 4+ weeks. If you have not progressed on any lift for a full mesocycle despite good nutrition and sleep, a split change can provide novel stimulus. See our guide to breaking plateaus.
• You transition experience levels. After 6-12 months on Full Body, most beginners should move to Upper/Lower or PPL to accommodate higher volume needs.
• Recovery becomes compromised. If you are constantly sore, fatigued, or your performance is declining, you may need a lower frequency split or a deload.

Do not change your split because:

• You are bored with your current routine
• You saw a new split on social media
• You have only been on your current split for 2-3 weeks

How MySetPlan Chooses Your Split

MySetPlan's quiz asks one key question: how many days per week can you train? Based on your answer, it selects the optimal split automatically:

• 4 days: Upper/Lower split
• 5 days: PPL variant (Push/Pull/Legs/Upper/Lower)
• 6 days: Full Push/Pull/Legs rotation

Every split follows 4-week mesocycles with progressive overload built in. Week 4 is always a deload (easy week) to manage fatigue. Your exercises are personalized based on your equipment, experience level, and goals — but the underlying split structure follows the evidence-based frameworks outlined in this guide.

If your schedule changes, you can update your training days and MySetPlan will adjust your split accordingly.
