How to Choose 5/3/1 Accessories: The Push/Pull/Legs Guide

Accessories are the part of 5/3/1 that trips people up the most. The main lifts and wave structure are straightforward — percentages are prescribed, you follow the plan. But when Wendler says “do 25–50 reps of push, pull, and single-leg/core,” you’re left making decisions. And for a lot of lifters, too many decisions means either paralysis or poor choices.

This guide covers Wendler’s push/pull/legs-core framework, how to select exercises that actually support your main lifts, and how to structure accessories so they help rather than hinder your progress.

The Push/Pull/Legs-Core Framework

Wendler’s accessory system is built on balance. Every training session, regardless of which main lift you’re doing, includes work from three categories:

Push — any pressing or tricep-dominant movement: dips, dumbbell bench, incline press, push-ups, overhead dumbbell press, tricep extensions.

Pull — any rowing or bicep-dominant movement: chin-ups, pull-ups, barbell rows, dumbbell rows, face pulls, band pull-aparts, curls.

Single-Leg/Core — unilateral lower body work and core stability: lunges, Bulgarian split squats, step-ups, leg curls, ab wheel, hanging leg raises, planks, pallof press.

The prescription is simple: 25–50 reps of each category per session. That’s a wide range by design. On a hard squat day with BBB supplemental work, you might stick to 25 reps per category. On a lighter OHP day, you might push toward 50.

Why This System Works

The push/pull/legs-core framework solves three problems simultaneously:

1. It Prevents Imbalances

Most lifters naturally bias toward pressing movements. Without a structured pull requirement, the typical gym session becomes bench, overhead press, and more bench variations. The mandatory pull work ensures your upper back, rear delts, and biceps keep pace with your pressing muscles.

2. It Protects Your Joints

Balanced pushing and pulling means your shoulders stay healthy. Adequate single-leg work means your knees and hips stay balanced. Core work means your spine stays supported under heavy loads. This is injury prevention disguised as accessory work.

3. It Builds What the Main Lifts Miss

Squats, bench, deadlifts, and OHP are excellent movements, but they have blind spots. None of them directly train the rear delts. None of them isolate the hamstrings. None of them train rotational core stability. Accessories fill those gaps.

Selecting Exercises by Main Lift Day

The best accessory choices complement what you’ve already done in that session. Here’s how to think about it:

Squat Day

You’ve already hammered your quads, glutes, and lower back. Your accessories should target what the squat missed and support recovery.

• Push: dips, DB bench press, or push-ups (upper body work that doesn’t tax the lower back)
• Pull: chin-ups or lat pulldowns (vertical pulling builds the shelf for the bar)
• Single-Leg/Core: leg curls and ab wheel (hamstrings need direct work; core stability supports heavy squats)

Bench Day

Your chest, front delts, and triceps have done the heavy lifting. Balance with pulling and lower body work.

• Push: DB incline press or overhead tricep extensions (target a different pressing angle)
• Pull: face pulls and barbell rows (rear delts and upper back support bench stability)
• Single-Leg/Core: lunges and pallof press (maintain lower body frequency without heavy loading)

Deadlift Day

Your entire posterior chain is fatigued. Go light on lower back stress in accessories.

• Push: DB shoulder press or dips (vertical pressing for shoulder health)
• Pull: chest-supported rows or cable rows (remove lower back from the pulling equation)
• Single-Leg/Core: back extensions at bodyweight and hanging leg raises (gentle posterior chain and core work)

OHP Day

Your shoulders and triceps have worked hard. Balance with pulling and lower body emphasis.

• Push: close-grip bench or tricep pushdowns (target lockout strength that helps both OHP and bench)
• Pull: band pull-aparts and chin-ups (high-rep rear delt work, lat engagement)
• Single-Leg/Core: Bulgarian split squats and planks (unilateral leg strength, anti-extension core)

The Rep Range Question: 25 vs 50

Wendler gives you a range for a reason. Here’s how to decide:

Go with 25 reps when:

• Your supplemental volume is high (BBB at 60%, for example)
• You’re in a caloric deficit
• You’re pressed for time
• It’s a particularly hard main lift day (heavy deadlift day, 5/3/1 week)

Go with 50 reps when:

• You have energy and time
• Your supplemental volume is moderate (FSL, lighter BBB)
• You’re eating in a surplus and recovering well
• You’re trying to bring up a specific weak point

Most lifters settle around 30–40 reps per category as a practical default. That typically means 3 sets of 10–15 reps per exercise.

Equipment Considerations

Not everyone trains in a fully equipped gym. Here’s how to make the framework work with limited gear:

Home Gym With Barbell Only

• Push: close-grip bench, floor press
• Pull: barbell rows, Pendlay rows
• Single-Leg/Core: good mornings, barbell lunges, sit-ups

Home Gym With Barbell + Pull-Up Bar

• Push: dips (between chairs if needed), push-up variations
• Pull: chin-ups, pull-ups, inverted rows
• Single-Leg/Core: single-leg deadlifts, hanging knee raises

Home Gym With Dumbbells + Bands

• Push: DB press variations, banded push-ups
• Pull: DB rows, band pull-aparts, band face pulls
• Single-Leg/Core: DB lunges, DB step-ups, banded pallof press

The exercises matter less than the balance. As long as you’re hitting push, pull, and single-leg/core with adequate reps, you’re following the program.

Common Accessory Mistakes

Treating Accessories Like Main Lifts

Accessories are not the place to chase heavy singles or grind through difficult sets. Use moderate weight, controlled reps, and focus on the muscle you’re trying to work. If your rows look like a full-body convulsion, the weight is too heavy.

Doing Too Many Exercises

You don’t need four push exercises, three pull exercises, and two core exercises per session. One exercise per category at 25–50 reps is the standard prescription. Two exercises when you want variety. Three is almost always unnecessary.

Ignoring Pull Work

This is epidemic. Lifters will do their main bench, their BBB bench, then three more pressing accessories. Meanwhile their pull work is one lazy set of face pulls. If anything, err on the side of more pulling — your shoulders will thank you.

Changing Exercises Every Session

Pick exercises you can progressively overload over multiple cycles. If you’re doing dumbbell rows, stick with them for at least 2–3 cycles and try to add reps or weight over time. Constantly rotating exercises prevents you from tracking progress on any of them.

Skipping Single-Leg and Core

This category is the most commonly skipped and arguably the most important. Single-leg work addresses asymmetries that bilateral squats and deadlifts can mask. Core work builds the stability that lets you handle heavier main lifts. Don’t skip it.

A Simple Starting Template

If you’re paralyzed by choice, start here. Run this for two full cycles, then adjust based on what you learn:

This hits every category with sensible exercise selection and manageable volume. Adjust rep counts to stay within the 25–50 range.

Let the Program Do the Thinking

The push/pull/legs-core framework is simple on paper but requires you to make good choices consistently. If you’d rather focus on executing your training instead of programming it, Train531 uses AI to select accessories based on your main lift day, available equipment, and training history — so every session is balanced without you having to think about it.
