🔄 Execution

The Movement

🔝 Starting Position

What's happening: Standing with asymmetric load, ready to lunge

1. Weight held at side in one hand
2. Core braced hard
3. Shoulders level (not tilted)
4. Torso upright
5. Ready to step

Feel: Weight pulling you slightly to one side — core working to resist

⬇️ Lowering into Lunge

What's happening: Stepping into lunge while fighting lateral pull

1. Step forward (or backward for reverse lunge)
2. Lower into lunge position
3. Front knee bends to ~90°
4. Back knee drops toward floor
5. Critical: Keep torso upright and shoulders level — don't lean toward weighted side

Tempo: 2 seconds

Feel: Working leg loading, core fighting hard to prevent lateral lean

⏸️ Bottom Position

What's happening: Full lunge position with offset load

1. Front knee at 90° (shin vertical)
2. Back knee hovering above floor
3. Torso still upright
4. Shoulders still level
5. Core maximally engaged

Common error here: Leaning or twisting toward the weighted side — stay tall and square.

⬆️ Returning

What's happening: Pushing back to standing

1. Drive through front heel
2. Extend front leg
3. Return to starting position
4. Maintain upright torso throughout
5. Keep core braced

Tempo: 1-2 seconds

Feel: Glute and quad of front leg contracting, core stabilizing

Key Cues

Primary Cues

• "Brace your core hard" — fight the pull to the side
• "Shoulders stay level" — don't tilt or lean
• "Stay tall" — upright torso throughout
• "Drive through the heel" — return with control

Tempo Guide

Goal	Tempo	Example
Strength	2-1-1-1	Controlled descent, brief pause
Hypertrophy	3-1-2-0	Slow eccentric, controlled concentric
Stability	2-2-1-1	Pause at bottom for core challenge

💪 Muscles Worked

Activation Overview

Primary Movers

Muscle	Action	Activation
Quadriceps	Knee extension — driving out of lunge	████████░░ 80%
Glutes	Hip extension — returning to standing	████████░░ 75%

Secondary Muscles

Muscle	Action	Activation
Hamstrings	Hip extension, knee control	██████░░░░ 60%
Core/Obliques	Anti-lateral flexion — resisting side bend	███████░░░ 70%
Hip Stabilizers	Prevents hip drop, maintains alignment	██████░░░░ 65%

Stabilizers

Muscle	Role
Erector Spinae	Maintains upright spine against offset load
Adductors	Inner thigh stability during lunge

Unique Benefit

Offset loading creates an anti-lateral flexion challenge for the core. Your obliques and deep core stabilizers must work hard to keep you from leaning sideways, making this far more than just a leg exercise.

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
Leaning toward weighted side	Torso tilts sideways	Reduces core challenge, spine stress	Brace harder, lighten load if needed
Shoulders tilting	One shoulder drops	Poor alignment, less stability work	Keep shoulders level
Knee caving inward	Valgus collapse	Knee injury risk	Push knee out over toes
Using too much weight	Cannot maintain upright posture	Form breakdown, injury risk	Use lighter weight
Front knee past toes	Knee shifts forward of foot	Excessive knee stress	Keep shin vertical

Most Common Error

Leaning toward the weighted side — this defeats the purpose. The entire point is to resist that pull. Start lighter than you think and prioritize staying perfectly upright.

Self-Check Checklist

• Shoulders level (not tilted)
• Torso upright (not leaning sideways)
• Front knee at 90°, shin vertical
• Back knee nearly touching floor
• Core braced throughout

🔀 Variations

By Direction

Forward Lunge

Variation	How	Emphasis
Offset Forward Lunge	Step forward with offset load	Dynamic, more quad
Same-side load	Weight on same side as lead leg	Standard challenge
Opposite-side load	Weight opposite lead leg	Increased core challenge

Reverse Lunge

Variation	How	Emphasis
Offset Reverse Lunge	Step backward with offset load	Easier on knees, more glute
Same-side load	Weight on same side as working leg	Moderate challenge
Opposite-side load	Weight opposite working leg	Higher core demand

Walking

Variation	How	When to Use
Walking Offset Lunge	Alternate legs, walk forward	More dynamic, conditioning
Switch weight each rep	Change hands each step	Maximum instability challenge

By Loading

Load Type	How	Core Challenge
Light offset	10-20 lbs one side	Moderate
Heavy offset	30-50+ lbs one side	High
Alternating hands	Switch each rep	Maximum
Two different weights	Heavy one side, light other	Advanced anti-rotation

📊 Programming

Rep Ranges by Goal

Goal	Sets	Reps (each leg)	Rest	Notes
Strength	3-4	6-10	90s	Moderate offset load
Hypertrophy	3-4	8-12	60-90s	Focus on leg work + stability
Stability/Core	3	10-15	60s	Lighter load, perfect form

Workout Placement

Program Type	Placement	Rationale
Leg day	Secondary exercise	After main lifts
Full body	Unilateral leg work	Single-leg + core combo
Core training	Primary movement	Anti-lateral flexion focus

Progression Scheme

How to Progress

Start with a light dumbbell (10-20 lbs). When you can do 3x10-12 per leg with perfect upright posture, increase weight by 5-10 lbs. You can also increase difficulty by holding the weight on the opposite side.

Exercise	When to Use
Bodyweight Lunge	Learning lunge mechanics
Goblet Lunge	Adding load but keeping it centered
Split Squat	Stationary, easier balance

Progressions (Harder)

Exercise	When Ready
Heavy Offset Lunge	Mastered 25-30 lbs offset
Overhead Lunge	Weight held overhead for more core challenge
Walking Offset Lunge	Dynamic movement + offset load

Similar Exercises

Alternative	When to Use
Suitcase Lunge	Similar offset challenge
Bulgarian Split Squat	More quad/glute, less core
Dumbbell Lunge (both sides)	Symmetric loading

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Lower back issues	Offset load creates lateral stress	Use lighter weight, or do goblet lunges
Knee pain	Lunge depth may aggravate	Reduce depth, try reverse lunge
Balance issues	Offset load makes balance harder	Hold wall or use lighter weight
Shoulder issues	Holding weight at side	May be fine, but monitor

Stop Immediately If

• Sharp pain in lower back
• Knee pain or instability
• Unable to maintain upright posture
• Dizziness or loss of balance

Training Tips

• Start with a lighter weight than you'd use for bilateral lunges
• Master bodyweight lunges before adding offset load
• Focus on quality over quantity — don't rush reps
• If you feel yourself leaning, reduce the weight

🦴 Joints Involved

Joint	Action	ROM Required	Stress Level
Hip	Flexion/extension, stabilization	Full range	🟡 Moderate
Knee	Flexion to extension	Deep flexion (~90°)	🟡 Moderate
Ankle	Dorsiflexion	Moderate	🟢 Low
Spine	Anti-lateral flexion	Neutral position held	🟡 Moderate

Core Challenge

The offset load creates a lateral (sideways) pulling force on your spine. Your core must actively resist this, making the exercise as much about core stability as leg strength.

❓ Common Questions

Which side should hold the weight?

You can do either. Holding weight on the same side as the working leg is standard. Holding it on the opposite side creates a greater anti-rotation challenge. Try both and see what you prefer.

How is this different from a suitcase lunge?

They're very similar. "Offset lunge" and "suitcase lunge" are often used interchangeably. Both involve holding weight on one side during a lunge to challenge core stability.

Should I feel my core working?

Absolutely! Your obliques and deep core stabilizers should be working hard to keep you upright. If you don't feel your core, you might be using too light a weight or not bracing properly.

Can I do these for core training instead of leg training?

Yes! While they work the legs, the offset load makes them excellent for anti-lateral flexion core training. Use them in core-focused workouts with moderate weight and higher reps.

For Mo

When to recommend this exercise:

• User wants to combine leg work with core stability
• User has mastered standard lunges and needs progression
• User wants to address core anti-lateral flexion strength
• User needs variety in single-leg training

Who should NOT do this exercise:

• Acute lower back injury → Wait for recovery
• Acute knee injury → Wait for recovery
• Cannot perform bodyweight lunges with good form → Master those first

Key coaching cues to emphasize:

1. "Brace your core hard — don't let the weight pull you sideways"
2. "Keep your shoulders level"
3. "Stay tall and upright"

Common issues to watch for in user feedback:

• "I keep leaning to one side" → Weight too heavy, reduce load and focus on form
• "I don't feel my core" → Cue harder bracing, may need slightly heavier weight
• "My knee hurts" → Check form (shin vertical, knee tracking), may try reverse lunge variation

Programming guidance:

• For intermediates: 3x8-10 per leg, 2x per week
• Start with 10-20 lbs and progress gradually
• Can be used as primary leg exercise or as accessory after squats/deadlifts
• Progress when: Can maintain perfect upright posture for 3x10-12 per leg
