Movement Summary

🎯 Setup

Starting Position

Cable height: Set high (above head level) for high-to-low variation
Position: Half-kneeling — inside knee down (knee closest to cable)
Stance: Back knee on pad, front foot flat, both at 90° angles
Grip: Both hands on handle/rope overhead and slightly toward cable
Posture: Tall spine, chest up, core braced
Starting position: Handle high and toward cable anchor
Weight: Start light to learn the pattern

Half-Kneeling Setup Details

Element	Specification
Inside knee	Down on pad/floor (knee closest to cable)
Outside knee	Up, foot flat on floor
Hip alignment	Square, both hips facing forward
Torso	Tall and upright
Distance from cable	2-3 feet away

Setup Cue

"Inside knee down — the knee closest to the cable is on the ground. You'll pull diagonally across your body from high to low"

Variation: Low-to-High

For low-to-high woodchop, simply reverse:

Set cable LOW (near floor)
Start with handle low and toward cable
Chop diagonally UP across your body

🔄 Execution

The Movement (High-to-Low)

🔝 Starting Position
⬇️ The Chop
⏸️ Bottom Position
⬆️ Return

What's happening: Handle high, ready to chop down

Both hands gripping handle overhead and toward cable
Arms slightly bent
Half-kneeling position stable
Core braced, torso rotated slightly toward cable
Eyes follow hands

Feel: Tension in the cable, ready to pull diagonally down

Key Cues

Primary Cues

"Chop wood diagonally" — high to low across your body
"Lead with your core, not your arms" — rotation drives the movement
"Stay tall in half-kneeling" — don't lean or collapse
"Control the return" — don't let cable snap you back

💪 Muscles Worked

Activation Overview

Primary Movers

Muscle	Action	Activation
Obliques	Rotate torso diagonally — driving the chopping motion	`██████████` 90%
Transverse Abdominis	Core stability — prevents unwanted movement	`████████░░` 75%

Secondary Muscles

Muscle	Action	Activation
Shoulders	Pull handle down (especially in high-to-low)	`███████░░░` 70%
Lats	Assist in pulling motion	`███████░░░` 65%

Stabilizers

Muscle	Role
Glutes	Stabilize pelvis in half-kneeling
Hip Flexors	Maintain half-kneeling position
Erector Spinae	Keep spine neutral

Unique Benefit

Half-kneeling woodchop trains rotation in multiple planes — it's not just transverse rotation, but diagonal movement that mimics real-world actions like throwing, swinging, and lifting.

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
All arms, no core	Pulling with arms only	Defeats purpose, less core work	Lead with rotation, arms follow
Wrong knee down	Outside knee down instead of inside	Unstable, harder to rotate	Inside knee (closest to cable) down
Leaning/collapsing	Losing tall posture	Less core work, back stress	Stay tall, brace core
Using momentum	Jerky, fast movement	Less control, injury risk	Slow, controlled movement
Excessive arm bend	Bending elbows a lot	Becomes an arm exercise	Keep arms relatively straight

Most Common Error

Using arms instead of core — this should be a rotational core exercise. Your arms are just holding the handle; the movement comes from rotating your torso.

Self-Check Checklist

Inside knee down (knee closest to cable)
Tall posture maintained throughout
Rotation comes from core, not arms
Controlled movement in both directions
Hips stay square (not rotating excessively)

Low-to-High	Cable low, chop up	Different angle

Variation	How	When to Use
Standing Woodchop	Standing instead of kneeling	More functional

Reps by Goal

Goal	Sets	Reps/Side	Rest	Notes
Strength	3-4	6-8	90s	Heavier resistance
Hypertrophy	3-4	8-12	60s	Moderate resistance

Athletic training	Power accessory	Builds rotational power
Full-body	Core finisher	After main lifts
Warm-up	Activation	Light reps to prep core

Progression Scheme

How to Progress

When you can perform 10+ controlled reps per side, either add resistance or progress to standing woodchop for more functional challenge.

🔄 Alternatives & Progressions

Exercise Progression Path

Regressions (Easier)

Exercise	When to Use
Tall-Kneeling Woodchop	Building base stability
Pallof Press Half-Kneeling	Learning anti-rotation first

Progressions (Harder)

Exercise	When Ready
Standing Woodchop	Want more functional movement
Landmine Rotation	Want to add more load
Medicine Ball Slam	Elite power development

Alternatives

Alternative	When to Use
Cable Woodchop (standing)	No kneeling position needed
Pallof Rotation	Different rotation angle
Russian Twist	Bodyweight alternative

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Lower back pain	Rotation can aggravate	Start very light, focus on form
Disc issues	Rotation under load stresses discs	Get clearance from PT first
Shoulder pain	Overhead position and pulling	Try low-to-high instead, or regress
Knee pain	Kneeling position	Use thick pad OR do standing variation

Stop Immediately If

Sharp pain in lower back during rotation
Shoulder pain during pulling motion
Knee pain in kneeling position
Unable to maintain neutral spine

Important Notes

Warm up thoroughly — rotational movements need warm muscles
Start LIGHT — this is about control and rotation, not heavy weight
Use a pad — protect your knee with a thick pad or mat

🦴 Joints Involved

Joint	Action	ROM Required	Stress Level
Spine (Thoracic)	Rotation	45-90°	🟡 Moderate
Shoulder	Flexion, pulling	Moderate	🟡 Moderate
Hip	Maintain half-kneeling	Moderate	🟢 Low
Knee	Kneeling position	Static	🟢 Low

Spine-Friendly

Half-kneeling position actually makes this MORE spine-friendly than standing because it limits excessive hip rotation and forces more thoracic (mid-back) rotation.

❓ Common Questions

Which knee should be down?

The inside knee — the knee CLOSEST to the cable anchor. If the cable is on your right, your right knee is down.

How is this different from standing woodchop?

Half-kneeling provides a more stable base and limits excessive hip rotation, forcing more thoracic spine rotation. It's also easier to learn the pattern. Standing is more functional and challenging.

Should I feel this in my arms?

Your arms will work, especially shoulders and lats, but the primary work should be in your core/obliques. If arms are burning way more than core, you're pulling too much with arms.

High-to-low or low-to-high — which is better?

Both are great! High-to-low is more common and emphasizes shoulders more. Low-to-high emphasizes upward rotation. Do both for complete development.

Can I use a resistance band instead of cable?

Absolutely! Anchor a band high (for high-to-low) and the movement is identical. Medicine balls also work great for this pattern.

For Mo

When to recommend this exercise:

User needs rotational core strength
User is an athlete (especially throwing, swinging, racquet sports)
User wants functional core training
User has good thoracic mobility

Who should NOT do this exercise:

Acute lower back injury → Wait for recovery
Disc herniation or severe disc issues → Get clearance from PT first
Acute shoulder injury → Wait for recovery
Cannot maintain neutral spine → Regress to pallof press first

Key coaching cues to emphasize:

"Inside knee down — the knee closest to the cable"
"Lead with your core, not your arms"
"Stay tall — don't collapse or lean"

Common issues to watch for in user feedback:

"I feel it all in my arms" → They're pulling with arms, not rotating with core
"My back hurts" → Weight too heavy OR poor form OR pre-existing issue
"Which knee goes down?" → Inside knee (closest to cable)
"My knee hurts" → Use thicker pad OR switch to standing variation

Programming guidance:

For intermediates: 3x8-10 per side, 2x/week as part of core work
For athletes: Include both high-to-low AND low-to-high for complete development
Progress when: 10+ controlled reps per side with perfect form
