🎯 Setup

Starting Position

1. Grip: Hold single dumbbell or kettlebell at your side (like carrying a suitcase)
2. Stance: Feet hip-width apart, standing tall
3. Arm: Weight-bearing arm hangs straight down
4. Shoulders: Level and square (not tilted)
5. Core: Braced hard to resist lateral pull
6. Free arm: At side or out slightly for balance
7. Head: Neutral, eyes forward

Suitcase Position Details

Element	Position	Why It Matters
Grip	Neutral, by side	Mimics carrying position
Shoulder	Packed down, not elevated	Prevents shoulder hike
Torso	Perfectly upright	Core must resist side bend
Opposite arm	Free for balance	Helps maintain stability

Setup Cue

"Carry the weight like a heavy suitcase — don't let it pull you sideways"

🔄 Execution

The Movement

🔝 Starting Position

What's happening: Standing tall with suitcase hold, ready to lunge

1. Weight hanging at side in neutral grip
2. Core braced to resist side pull
3. Shoulders level (fight the urge to hike the weighted shoulder)
4. Torso upright and centered
5. Ready to step

Feel: Weight pulling down on one side — core and shoulder stabilizers engaged to stay upright

⬇️ Descending into Lunge

What's happening: Stepping into lunge while maintaining upright torso

1. Step forward or backward (your choice)
2. Lower hips straight down
3. Front knee bends to ~90°
4. Back knee lowers toward floor
5. Critical: Keep torso upright, shoulders level — don't lean toward the weight

Tempo: 2 seconds

Feel: Working leg loading, core actively fighting lateral pull

⏸️ Bottom Position

What's happening: Full lunge position with suitcase load

1. Front knee at 90° (shin vertical)
2. Back knee hovering just above floor
3. Torso still perfectly upright
4. Shoulders still level
5. Weight still hanging straight down

Common error here: Leaning sideways or hiking the weighted shoulder — stay centered and tall.

⬆️ Returning to Start

What's happening: Driving back to standing position

1. Push through front heel
2. Extend front leg
3. Return to starting stance
4. Maintain upright torso throughout
5. Keep shoulders level

Tempo: 1-2 seconds

Feel: Glute and quad of working leg contracting, core stabilizing throughout

Key Cues

Primary Cues

• "Carry it like a heavy suitcase" — straight arm, packed shoulder
• "Don't let it pull you sideways" — core braces hard
• "Shoulders stay level" — no hiking or tilting
• "Stay tall" — upright torso from start to finish

Tempo Guide

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

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
Leaning toward weight	Torso tilts sideways	Defeats core challenge, spine stress	Brace harder, lighten load
Hiking weighted shoulder	Shoulder elevates up toward ear	Shoulder/neck tension, poor form	"Shoulder down and packed"
Knee caving in	Valgus collapse	Knee injury risk	Push knee out, align over toes
Using too heavy weight	Cannot maintain posture	Form breakdown	Lighter than bilateral lunges
Bouncing at bottom	Using momentum	Less control, injury risk	Controlled pause at bottom

Most Common Error

Hiking the weighted shoulder — when the weight gets heavy, people naturally shrug that shoulder up. Keep it packed down. If you can't, the weight is too heavy.

Self-Check Checklist

• Shoulders level (no hiking or tilting)
• Torso upright (not leaning sideways)
• Weight hanging straight down
• Front knee at 90°, shin vertical
• Core braced hard throughout

🔀 Variations

By Direction

Forward Lunge

Variation	How	Emphasis
Suitcase Forward Lunge	Step forward with suitcase hold	Dynamic, quad-dominant
Alternating	Switch legs each rep	More dynamic
Single-leg focus	All reps one leg, then switch	Increased time under tension

Reverse Lunge

Variation	How	Emphasis
Suitcase Reverse Lunge	Step backward with suitcase hold	Knee-friendly, glute emphasis
Controlled tempo	Slow eccentric	Hypertrophy focus

Walking

Variation	How	When to Use
Walking Suitcase Lunge	Continuous walking lunges	Conditioning, functional strength
Switch hands	Alternate weight side each step	Maximum core challenge

By Loading

Load Type	How	Challenge Level
Light (10-20 lbs)	Learning movement	Beginner-Intermediate
Moderate (25-40 lbs)	Standard training	Intermediate
Heavy (45+ lbs)	Serious load	Advanced
Switch sides	Alternate hand each set	Balanced development

📊 Programming

Rep Ranges by Goal

Goal	Sets	Reps (each leg)	Rest	Notes
Strength	3-4	6-10	90s	Heavier suitcase load
Hypertrophy	3-4	8-12	60-90s	Moderate load, controlled tempo
Stability/Core	3	10-15	60s	Lighter load, perfect posture

Workout Placement

Program Type	Placement	Rationale
Leg day	Accessory exercise	After main squats/deadlifts
Full body	Unilateral leg slot	Leg + core combo
Core/stability	Primary movement	Anti-lateral flexion work

Progression Scheme

How to Progress

Start with 10-20 lbs. When you can do 3x10-12 per leg with perfect upright posture and no shoulder hiking, add 5-10 lbs. The suitcase lunge uses less weight than bilateral movements — that's normal.

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Lower back issues	Lateral loading creates stress	Use lighter weight or centered load
Shoulder problems	Holding heavy weight at side	May aggravate, use light weight
Knee pain	Lunge depth can irritate	Reduce depth, try reverse lunge
Balance issues	Offset load challenges balance	Use support or lighter weight

Stop Immediately If

• Sharp lower back pain
• Shoulder pain or inability to keep shoulder down
• Knee pain or instability
• Cannot maintain upright posture
• Dizziness

Training Tips

• Start lighter than you think — suitcase loading is humbling
• Keep shoulder "packed" (down and back, not hiked up)
• Don't rush — control and posture are the priority
• If you're leaning, the weight is too heavy

🦴 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	Held neutral	🟡 Moderate
Shoulder	Stabilization	Minimal movement	🟢 Low

Real-World Carryover

The suitcase lunge trains the exact stability pattern you use when carrying uneven loads in real life — groceries, luggage, a kid on one hip. This is functional strength at its best.

❓ Common Questions

Is this the same as an offset lunge?

Yes, essentially. "Suitcase lunge" and "offset lunge" both refer to holding weight on one side during a lunge. The terms are often used interchangeably.

Which side should hold the weight relative to the working leg?

Either works. Same-side loading (weight on same side as front leg) is standard. Opposite-side creates more anti-rotation demand. Both are valuable — try both.

Why does my shoulder want to hike up?

That's a natural response to heavy load. It means the weight is too heavy for your current shoulder/core stability. Lighten the load and focus on keeping that shoulder "packed down."

How much lighter should the weight be compared to bilateral lunges?

Typically 30-50% lighter. If you use 40 lb dumbbells for regular lunges (20 lbs each hand), you might use 15-25 lbs for suitcase lunge. The core challenge limits the load.

Can this replace regular lunges?

It can, but it's better as a complement. Regular bilateral lunges allow heavier leg loading. Suitcase lunges add core stability. Use both for complete development.

For Mo

When to recommend this exercise:

• User wants functional strength for real-world activities
• User has mastered standard lunges and needs progression
• User wants to combine leg strength with core stability work
• User wants variety in single-leg training

Who should NOT do this exercise:

• Acute lower back injury → Wait for recovery
• Acute shoulder injury → May need to avoid or use very light weight
• Cannot perform bodyweight lunges properly → Master those first
• Severe balance issues → Use regression or alternative

Key coaching cues to emphasize:

1. "Shoulder down and packed — don't let it hike up"
2. "Stay perfectly upright — don't lean toward the weight"
3. "Carry it like a heavy suitcase you don't want to drop"

Common issues to watch for in user feedback:

• "My shoulder hurts" → Weight too heavy, or shoulder not packed properly
• "I keep leaning sideways" → Weight too heavy OR not bracing core hard enough
• "This feels easy" → Probably pushing off back leg too much, or weight too light

Programming guidance:

• For intermediates: 3x8-10 per leg, 1-2x per week
• Start with 10-20 lbs max (lighter than you think!)
• Can be primary leg exercise or accessory after heavy squats
• Progress when: Can maintain perfect upright posture for 3x10-12 per leg with current weight
• Pair with: Bilateral leg exercises for complete leg development
