Movement Summary

🎯 Setup

Starting Position

1. Bar setup: Barbell loaded with round plates (45lb/20kg work best)
2. Position: Kneel on mat or padded surface behind barbell
3. Grip: Overhand grip, shoulder-width apart
4. Arms: Fully extended, locked out
5. Torso: Upright, core braced hard
6. Knees: Hip-width apart for stability

Equipment Notes

Component	Specification	Why
Plates	Round, 45lb/20kg preferred	Allows smooth rolling
Surface	Smooth floor	Bar needs to roll freely
Knee padding	Mat or pad	Protect knees during movement

Setup Cue

"Brace like someone's about to punch you in the gut — maintain that tension the entire movement"

🔄 Execution

The Movement

🔝 Starting Position

What's happening: Kneeling upright, ready to roll

1. Kneeling tall, barbell in front
2. Hands gripping bar shoulder-width
3. Arms locked out
4. Core maximally braced
5. Shoulders packed, lats engaged

Feel: Full-body tension, core tight

⬇️ Rolling Out

What's happening: Controlled roll forward into extension

1. Slowly roll barbell forward along floor
2. Extend arms and torso as one unit
3. Keep core braced — RESIST arching lower back
4. Roll out until nearly parallel to floor
5. Do NOT let hips sag or back arch

Tempo: 3-4 seconds

Feel: Intense core activation, shoulders working to stabilize, abs stretched

Critical: This is anti-extension — you're fighting gravity's attempt to pull your lower back into hyperextension.

⏸️ Extended Position

What's happening: Maximum stretch, near-parallel to floor

1. Body extended, arms overhead
2. Core still maximally braced
3. Hips slightly flexed (not sagging)
4. Body forms diagonal line from knees to hands
5. Brief pause at full extension

Common error here: Lower back arching — if this happens, you went too far. Reduce range of motion.

⬆️ Pulling Back

What's happening: Pulling barbell back to start position

1. Pull barbell back using core and lats
2. Think "crunch the bar back" not just arm pull
3. Keep arms straight throughout
4. Return to upright kneeling position
5. Maintain core brace entire way

Tempo: 2-3 seconds

Feel: Core contracting hard, lats engaging, shoulders working

Key Cues

Primary Cues

• "Brace like hell" — maximal core tension from start to finish
• "Don't let your back arch" — anti-extension is the goal
• "Pull with your abs, not just arms" — core drives the return
• "Only go as far as you can control" — no ego, perfect form only

Tempo Guide

Goal	Tempo	Example
Strength	4-1-2-1	4s out, 1s pause, 2s back, 1s rest
Hypertrophy	3-1-3-0	3s out, 1s pause, 3s back
Endurance	2-0-2-0	Controlled rhythm

💪 Muscles Worked

Activation Overview

Primary Movers

Muscle	Action	Activation
Rectus Abdominis	Anti-extension — preventing lower back from arching	█████████░ 90%
Core Stabilizers	Total core bracing and stability	█████████░ 85%

Secondary Muscles

Muscle	Action	Activation
Latissimus Dorsi	Pulls bar back, shoulder stabilization	███████░░░ 65%
Anterior Deltoid	Shoulder stabilization in overhead position	██████░░░░ 60%

Stabilizers

Muscle	Role
Hip Flexors	Prevent hips from sagging
Serratus Anterior	Stabilize shoulder blades
Obliques	Prevent lateral spinal flexion

Unique Benefit

Barbell rollouts train anti-extension better than planks because they actively challenge your core's ability to resist extension under increasing leverage — a dynamic stability demand that static holds can't replicate.

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
Lower back arching	Spine hyperextends	Defeats the purpose, risks injury	Reduce range, brace harder
Going too far	Can't maintain neutral spine	Lower back pain, poor control	Stop before back arches
Pulling only with arms	Arms do work instead of core	Misses core training effect	Think "crunch bar back"
Hips sagging	Hip flexors collapse	Lower back compensates	Engage hip flexors, reduce range
Losing brace	Core relaxes during movement	Dangerous for spine	Reset, brace harder from start

Most Common Error

Lower back arching — this is the #1 mistake. If your back arches, STOP. Reduce your range of motion. Only roll out as far as you can maintain a neutral or slightly flexed spine.

Self-Check Checklist

• Core maximally braced from start to finish
• Lower back stays neutral or slightly flexed (never arched)
• Arms stay straight throughout
• Controlled tempo, no momentum
• Can pull bar back using core, not just arms

🔀 Variations

By Difficulty

Easier (Regressions)

Variation	How	When to Use
Ab Wheel Kneeling	Use ab wheel instead of barbell	Still building core strength
Reduced Range	Don't roll out as far	Can't maintain neutral spine full range
Wall Rollout	Roll out to wall at set distance	Learning movement pattern

Standard

Variation	How	Emphasis
Kneeling Barbell Rollout	Standard execution	Core anti-extension
Paused Rollout	Hold extended position 2-5s	Increased time under tension

Harder (Progressions)

Variation	How	When to Use
Standing Rollout	From standing position	Elite core strength
Single-Arm Rollout	One arm at a time	Anti-rotation challenge
Weighted Vest	Add load to body	Want more resistance

By Target

Target	Variation	Change
More Core	Longer hold at extension	Pause 3-5s at bottom
Lat Emphasis	Focus on pull back	Aggressive lat engagement
Shoulders	Wider grip	Hands wider than shoulders
Obliques	Diagonal rollouts	Roll out at 45° angles

📊 Programming

Rep Ranges by Goal

Goal	Sets	Reps	Rest	Notes
Strength	3-4	5-8	90-120s	Full range, slow tempo
Hypertrophy	3-4	8-12	60-90s	Control eccentric
Endurance	2-3	12-15	60s	Consistent pace

Workout Placement

Program Type	Placement	Rationale
Core day	Primary	Main core movement
Upper body	Finisher	Accessory core work
Full body	Accessory	After main lifts

Progression Scheme

How to Progress

When you can do 3 sets of 10 with perfect form and full range, progress to standing rollouts or add a 3-5s pause at the extended position.

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Lower back pain	Hyperextension can aggravate	Reduce range, focus on anti-extension
Shoulder issues	Overhead loading	Start with limited range
Weak core	Can't control movement	Regress to ab wheel or plank

Stop Immediately If

• Sharp pain in lower back
• Inability to maintain neutral spine
• Shoulder pain
• Feeling of instability or loss of control

Absolute Contraindications

• Acute lower back injury
• Herniated disc (without medical clearance)
• Acute shoulder injury
• Pregnancy (third trimester)

🦴 Joints Involved

Joint	Action	ROM Required	Stress Level
Spine	Anti-extension stabilization	Neutral maintenance	🔴 High
Shoulder	Overhead stabilization	~150-180° flexion	🟡 Moderate
Hip	Hip flexion control	Partial flexion	🟡 Moderate

Spine Safety

The entire point is to keep your spine neutral. If you can't maintain a neutral or slightly flexed spine, reduce range of motion immediately.

❓ Common Questions

How is this different from ab wheel rollouts?

Mechanically they're very similar. The barbell version is generally slightly more challenging due to the higher starting position and the grip on a thicker bar. Ab wheel is more portable and accessible.

Should my lower back arch at all during this movement?

No. The goal is anti-extension — preventing your lower back from arching. If your back arches, you've gone too far. Reduce range of motion.

How far out should I roll?

Only as far as you can maintain perfect spinal position. For some that's 2 feet, for others it's nearly parallel to the floor. Form over distance.

Can I do this standing?

Only once you've mastered the kneeling version for high reps (15+) with perfect form. Standing rollouts are significantly harder.

For Mo

When to recommend this exercise:

• User has advanced core strength (can plank 90s+)
• User wants to progress beyond standard core exercises
• User has access to barbell and open floor space
• User has mastered ab wheel rollouts

Who should NOT do this exercise:

• Lower back injury or pain → Use regressions like plank or dead bug
• Weak core baseline → Build up with planks first
• No access to appropriate equipment → Use ab wheel instead

Key coaching cues to emphasize:

1. "Brace your core like someone's about to punch you"
2. "Do NOT let your lower back arch — that defeats the purpose"
3. "Only go as far as you can control with perfect form"

Common issues to watch for in user feedback:

• "My lower back hurts" → They're arching. Reduce range, cue anti-extension harder
• "I feel this in my arms/shoulders" → Need to engage core more, may be pulling with arms
• "I can't roll out very far" → Totally fine! This is advanced. Reduce range.

Programming guidance:

• For intermediate: 3x5-8 reps, 2x/week as part of core training
• For advanced: 3x8-12 reps, can be done 2-3x/week
• Progress when: Can do 3x12 with full range and perfect form
• Next step: Standing rollouts or add pauses
