🎯 Setup

Starting Position

1. Kneeling position:

   • If pressing with right arm: Right knee down, left foot forward
   • If pressing with left arm: Left knee down, right foot forward
   • Rule: Down knee same side as pressing arm

2. Leg positioning:

   • Front foot flat, knee at 90°
   • Back knee directly under hip
   • Front shin vertical
   • Hips squared forward, not rotated

3. Torso:

   • Upright, no forward lean
   • Slight posterior pelvic tilt (tuck tailbone slightly)
   • Core braced as if taking a punch
   • Ribs down, not flared

4. Dumbbell position:

   • At shoulder on same side as down knee
   • Neutral or semi-pronated grip
   • Elbow under or slightly in front of dumbbell

5. Opposite arm: Down at side or on hip for balance

Equipment Setup

Equipment	Setting	Notes
Dumbbell	Lighter than standing press	Start with 60-70% of standing weight
Mat/Pad	Under back knee	Knee comfort and stability
Space	Clear overhead	Check ceiling clearance

Setup Cue

"Down knee same side as pressing arm, hips square, glute squeezed — create a stable pillar from knee to hand"

🔄 Execution

The Movement

🔧 Start Position

What's happening: Stable half-kneeling base

1. Half-kneeling position set
2. Dumbbell at shoulder (same side as down knee)
3. Core braced, ribs down
4. Back glute (down knee side) actively squeezed
5. Weight balanced between front foot and back knee
6. Eyes forward or slightly up

Critical: Squeeze the glute on the kneeling leg side — this prevents hyperextension

Feel: Stable, tall, ready to press

⬆️ Pressing Phase

What's happening: Drive dumbbell straight overhead

1. Take a breath, brace core harder
2. Press dumbbell straight up (not forward or out)
3. Elbow extends fully
4. Slight "punching" motion at top
5. Critical: Keep torso vertical — don't lean away

Tempo: 1-2 seconds (controlled power)

Feel: Shoulder and tricep pressing, core bracing to prevent movement

Common error here: Leaning away from the weight. Keep torso vertical.

🔝 Lockout

What's happening: Full overhead position

1. Arm fully extended
2. Bicep by ear
3. Dumbbell slightly in front of body (not behind head)
4. Shoulder actively shrugged up
5. Core still braced, hips still square
6. Back glute still squeezed

Hold: Brief moment (0.5-1 second)

Feel: Stable overhead, core working to resist rotation

⬇️ Lowering Phase

What's happening: Controlled descent to shoulder

1. Lower with control (don't drop)
2. Maintain vertical torso
3. Elbow tracks down same path
4. Return to shoulder
5. Reset core tension for next rep

Tempo: 2-3 seconds

Feel: Eccentric shoulder and tricep work, maintaining stability

Key Cues

Primary Cues

• "Squeeze the down-knee glute" — prevents hyperextension
• "Press straight up, not forward" — proper bar path
• "Tall torso, ribs down" — core stability
• "Stack the weight over your body" — alignment

Tempo Guide

Goal	Tempo	Example
Stability	3-1-3-1	3s up, 1s hold, 3s down, 1s reset
Strength	2-0-2-0	2s up, no pause, 2s down, no pause
Hypertrophy	2-1-3-1	2s up, 1s hold, 3s down, 1s reset

💪 Muscles Worked

Activation Overview

Primary Movers

Muscle	Action	Activation
Deltoids (Anterior/Medial)	Shoulder abduction/flexion — pressing overhead	████████░░ 85%
Core/Obliques	Anti-lateral flexion, anti-rotation	███████░░░ 70%

Secondary Muscles

Muscle	Action	Activation
Triceps	Elbow extension — lockout	██████░░░░ 65%
Glutes (kneeling side)	Hip extension, prevent hyperextension	█████░░░░░ 55%

Stabilizers

Muscle	Role
Rotator Cuff	Stabilize shoulder joint during press
Serratus Anterior	Scapular upward rotation, protraction
Core	Resist lateral flexion and rotation
Hip Flexors	Maintain half-kneeling position

Muscle Emphasis

Core advantage: 40-50% more oblique/core activation vs standing press due to unstable base and anti-lateral flexion demands. Shoulder isolation: Eliminates leg drive, making shoulders work harder than push press variations. Glute activation: The kneeling-side glute works at ~55% activation to prevent lumbar hyperextension.

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
Hyperextending lower back	Excessive arch, ribs flare	Lower back strain, inefficient	Squeeze glute, ribs down, posterior pelvic tilt
Leaning away from weight	Torso side-bends away	Loses core benefit, unstable	Lighter weight, cue vertical torso
Wrong knee down	Opposite knee down from pressing arm	Less stable, misses pattern	Down knee same side as pressing arm
Pressing forward	Weight goes forward not up	Poor bar path, shoulder stress	Cue "punch straight up to ceiling"
Front knee past toes	Knee collapses forward	Unstable base, knee stress	Front shin vertical, adjust stance
Hips rotated	Not square to front	Loses core challenge	Reset position, square hips forward

Most Common Error

Hyperextending the lower back — when you can't use leg drive, many people compensate by arching their back excessively. Squeeze the glute on your kneeling leg side and keep ribs down to maintain neutral spine.

Self-Check Checklist

• Down knee is same side as pressing arm
• Hips are square forward, not rotated
• Torso vertical throughout press
• Glute on kneeling side actively squeezed
• Ribs stay down, no excessive arch
• Pressing straight up, not forward

📊 Programming

Rep Ranges by Goal

Goal	Sets	Reps (per arm)	Rest	Load	RIR
Stability	3-4	10-15	60-90s	50-60% standing max	3-4
Strength	3-4	6-8	90s-2 min	70-80% standing max	1-2

Endurance	2-3	15-20+	45-60s	40-50% standing max	3-4

Weight Selection

Half-kneeling press requires 20-40% less weight than standing press due to stability demands and no leg drive. If you press 50lbs standing, start with 30-35lbs half-kneeling.

Workout Placement

Program Type	Placement	Rationale
Upper/Lower	Middle to late on upper day	Accessory after main pressing
Push/Pull/Legs	Middle of push day	After heavy compounds
Full-body	After main lifts	Core-integrated accessory
Shoulder day	Middle to late	After heavy overhead work

Frequency

Training Level	Frequency	Volume Per Session
Beginner	1-2x/week	3 sets per arm
Intermediate	2x/week	3-4 sets per arm
Advanced	2-3x/week	3-4 sets per arm

Progression Scheme

Progressive Overload

Prioritize perfect position over weight. A lighter weight with perfect vertical torso and no lean is far more effective than heavier weight with compensation.

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Shoulder impingement	Pain overhead	Landmine press, reduce ROM
Knee pain	Pressure on kneeling knee	Thick pad, tall kneeling, or standing
Lower back pain	Hyperextension risk	Focus on glute squeeze, ribs down, lighter weight
Hip flexor tightness	Discomfort in front hip	Stretch hip flexors, adjust stance

Stop Immediately If

• Sharp shoulder pain during press
• Knee pain beyond mild discomfort
• Lower back sharp pain
• Feeling unstable or losing balance
• Dizziness

Form Breakdown Indicators

Sign	Meaning	Action
Torso leaning away >10°	Weight too heavy	Reduce load 20-30%
Excessive back arch	Core weakness or poor cuing	Squeeze glute, ribs down, lighter weight
Hips rotating	Instability or compensation	Square hips, lighter weight
Front knee wobbling	Unstable base	Adjust stance width
Unable to lockout	Fatigue or too heavy	End set or reduce weight

Safe Failure

How to safely fail:

1. Mid-rep: Lower dumbbell to shoulder with control
2. At top: Control descent, don't drop
3. Lost balance: Place non-working hand on ground for support
4. Knee pain: Stop immediately, stand up, assess

Position Critical

The half-kneeling position requires good hip and core control. If you have knee issues, use extra padding or choose tall kneeling (both knees) or standing variations.

Knee Comfort

Issue	Solution
Knee pain	2-3" thick pad or folded mat
Hard floor	Yoga mat, gym mat, or cushion
Kneecap discomfort	Pad directly under kneecap
Persistent pain	Avoid kneeling variations, use standing

🦴 Joints Involved

Joint	Action	ROM Required	Stress Level
Shoulder	Abduction, flexion to overhead	Full overhead ROM	🟡 Moderate
Elbow	Extension	~90-180°	🟢 Low-Moderate
Hip (kneeling side)	Extension, stability	Full hip extension	🟡 Moderate
Hip (front side)	Flexion at 90°	90° flexion	🟢 Low
Spine	Anti-lateral flexion, stabilization	Minimal movement	🟡 Moderate

Mobility Requirements

Joint	Minimum ROM	Test	If Limited
Shoulder	Full overhead flexion	Arms straight overhead without arching	Landmine press, mobility work
Hip (kneeling)	Full extension	Can kneel with vertical torso	Hip flexor stretching, standing variation
Thoracic	Adequate extension	Can reach overhead without compensating	T-spine mobility work

Joint Health Note

Half-kneeling position requires good hip extension on the kneeling side. If you have tight hip flexors, you may compensate with excessive back arch. Address hip mobility while using this exercise to improve it.

❓ Common Questions

Which knee should be down?

The knee on the same side as your pressing arm should be down. So if pressing with your right arm, your right knee is down and left foot is forward. This creates the proper challenge to your core and stability systems.

Why is this better than standing overhead press?

It's not "better" — it's different. Half-kneeling eliminates leg drive and challenges your core stability significantly more. Use it for core-integrated shoulder work, correcting imbalances, and building overhead stability. Use standing press for max strength and loading.

My lower back arches a lot — is this normal?

Some arch is natural, but excessive hyperextension indicates you need to: (1) squeeze the glute on your kneeling side harder, (2) perform a slight posterior pelvic tilt (tuck tailbone), (3) keep ribs down, or (4) use lighter weight. This is the most common compensation pattern.

Should I press straight up or at an angle?

Press straight up toward the ceiling, not forward or out to the side. The dumbbell should finish slightly in front of your body (over your shoulder), not behind your head. Think "punch straight up."

Can I do both arms at once?

You can, but you lose the unilateral and anti-rotation benefits. Half-kneeling is typically used for single-arm work. If you want to press both arms simultaneously in a kneeling position, try tall kneeling (both knees down).

How much weight should I use compared to standing press?

Start with 60-70% of your standing single-arm press weight. The unstable base and inability to use leg drive mean you'll use significantly less weight. Focus on stability and control, not maximum load.

For Mo

When to recommend this exercise:

• User wants overhead pressing with core integration
• User mentions lower back issues with standing overhead press (often uses excessive arch)
• User needs unilateral shoulder work
• User is working on shoulder stability and control
• User has imbalances between left and right shoulders
• User wants to eliminate leg drive to isolate shoulders

Who should NOT do this exercise:

• Acute shoulder injury → Suggest landmine press or horizontal pressing
• Severe knee pain → Suggest standing or seated variations
• Cannot kneel → Suggest standing single-arm press
• No overhead mobility → Work on mobility, use landmine press
• Complete beginner → Start with Seated Dumbbell Press

Key coaching cues to emphasize:

1. "Down knee same side as pressing arm"
2. "Squeeze the glute on your kneeling side"
3. "Ribs down, vertical torso"
4. "Press straight up to the ceiling"

Common issues to watch for in user feedback:

• "My back arches a lot" → Squeeze glute harder, cue ribs down, reduce weight
• "I feel unstable" → Normal at first, reduce weight, ensure proper stance setup
• "My knee hurts" → Add more padding, or switch to standing variation
• "I'm leaning to the side" → Weight too heavy, cue vertical torso
• "I don't feel my shoulders" → Normal — more core demand. Ensure pressing straight up.

Programming guidance:

• Pair with: Rows, pull-ups, core work, hip mobility
• Avoid same day as: Heavy overhead pressing may cause fatigue
• Typical frequency: 1-2x per week as accessory
• Volume: 3-4 sets per arm
• Place: Middle to late in workout after main compound lifts

Progression signals:

• Ready to progress when: Can maintain vertical torso with no lean, RIR 2-3, completing all reps
• Add weight: 2.5-5 lbs when position is perfect
• Progress to standing when: Want to load more weight, mastered stability
• Regress if: Excessive back arch, leaning, losing balance, knee pain

Alternative suggestions based on limitations:

• Knee pain → Tall kneeling (both knees) or standing single-arm press
• Shoulder mobility issues → Landmine press (angled path)
• Want more weight → Standing single-arm press
• Core focus → Pallof press, tall kneeling press
• No equipment → Pike push-ups, wall walks

Why this exercise is valuable:

• Exposes compensation patterns (excessive arch, leg drive)
• Builds true shoulder stability without cheating
• Integrates core into pressing
• Addresses left/right imbalances
• Improves hip extension (if tight hip flexors)
