🔄 Execution

The Movement

➡️ Step to Side

What's happening: Initiating lateral movement

1. Take a large step directly to the right (3-4 feet)
2. Land on heel, roll to full foot
3. Keep left leg straight (or soft knee)
4. Both feet point forward throughout
5. Breathing: Inhale during step

Step width: Wide enough to create significant stretch in left adductors

Feel: Stable landing, preparing to shift weight

⬇️ Shift & Lower

What's happening: Shifting weight and descending

1. Shift weight onto right leg
2. Push hips back (like a squat)
3. Bend right knee, keeping it aligned over foot
4. Lower until right thigh is parallel (or as low as mobility allows)
5. Left leg stays relatively straight, foot flat
6. Breathing: Continue inhale or hold

Tempo: 2-3 seconds

Feel: Right glute and quad loading, left adductor stretching

⏸️ Bottom Position

What's happening: Maximum lateral stretch and loading

1. Right thigh parallel to ground (or just above)
2. Right knee aligned over 2nd/3rd toe
3. Hips pushed back, chest up
4. Left leg straight with foot flat (heel down if possible)
5. Weight 90% on right leg
6. Torso upright or slight forward lean

Key position: This looks like a single-leg squat with the other leg stretched out

Feel: Deep stretch in left inner thigh, right glute loaded

⬆️ Push Back

What's happening: Driving back to center

1. Push through right heel powerfully
2. Drive right leg to push yourself back to center
3. Return to starting position with feet together
4. Reset and repeat, or alternate sides
5. Breathing: Exhale forcefully during push

Tempo: 1-2 seconds (powerful return)

Feel: Right glute and quad driving you back, left adductor pulling in

Key Cues

Primary Cues

• "Push your hips back, not just knee forward" — prevents knee-dominant pattern
• "Keep the straight leg's heel down" — maximizes adductor stretch
• "Push the floor away to come back" — activates glutes

Tempo Guide

Goal	Tempo	Example
Strength	2-1-1-1	2s down, 1s pause, 1s up, 1s reset
Mobility	3-2-2-1	3s down, 2s pause for stretch, 2s up
Conditioning	1-0-1-0	1s down, no pause, 1s up, continuous

💪 Muscles Worked

Activation Overview

Primary Movers

Muscle	Action	Activation
Quadriceps	Knee extension — straightening working leg	███████░░░ 75%
Glutes	Hip extension — pushing back to center	███████░░░ 75%
Adductors	Hip adduction — pulling back to center, stretching on straight leg	████████░░ 80%

Secondary Muscles

Muscle	Action	Activation
Hamstrings	Hip extension assist, knee stability	█████░░░░░ 50%
Abductors (Glute Med/Min)	Stabilize pelvis, control lateral movement	█████░░░░░ 55%

Stabilizers

Muscle	Role
Core	Maintain torso position during lateral shift, prevent rotation
Hip Stabilizers	Balance during single-leg loading, prevent hip drop

Muscle Emphasis

Lateral lunges are EXCEPTIONAL for adductors — one of the few exercises that significantly loads them both concentrically (pushing back) and eccentrically (stretching on straight leg). This makes them crucial for groin health and injury prevention.

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
Knee caving inward	Working knee collapses medially	Knee injury risk	"Knee out over pinky toe" cue
Heel lifting (straight leg)	Heel comes off ground	Less adductor stretch, poor form	Widen stance less, work on flexibility
Not sitting back	Knee shoots forward, no hip hinge	Knee stress, less glute work	"Push hips back like a squat"
Turning foot out	Rotating working foot outward	Defeats adductor stretch purpose	Keep both feet forward
Too narrow step	Small lateral step	Minimal adductor work/stretch	Step out 3-4 feet
Leaning forward excessively	Torso drops toward floor	Balance issues, back stress	Chest up, weight in heel

Most Common Error

Allowing the straight leg's heel to lift — this defeats the adductor stretch and often indicates stepping too wide for your current mobility. Start narrower and progress to wider steps.

Self-Check Checklist

• Both feet pointing straight forward
• Working knee aligned over foot (not caving)
• Straight leg's heel stays flat
• Hips pushed back, not just knee forward
• Can feel stretch in inner thigh of straight leg

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Groin strain history	Re-injury if pushed too far	Start narrow, progress slowly
Hip impingement	Pinching in working hip	Limit depth, try narrower stance
Knee pain (medial)	Adductor insertion stress	Reduce depth, check knee alignment
Poor adductor flexibility	Overstretching, pulling muscle	Start with narrow stance, progress gradually

Stop Immediately If

• Sharp groin/adductor pain (not stretch sensation)
• Knee pain (especially inside of knee)
• Hip pinching or clicking with pain
• Loss of balance repeatedly

Groin Injury Prevention

Lateral lunges are excellent for groin health BUT must be progressed carefully:

Risk Factor	Prevention Strategy
Going too wide too soon	Start with comfortable width, add 6 inches per week
Cold muscles	Always warm up first, never use as first exercise cold
Excessive loading	Master bodyweight before adding significant load
Ignoring pain	Stretch sensation is okay, sharp pain is not

Surface and Footwear

Factor	Recommendation
Surface	Non-slip essential — lateral movement increases slip risk
Shoes	Good lateral support, flat sole (not running shoes)
Barefoot	Okay for bodyweight if experienced, but less stable

🦴 Joints Involved

Joint	Action	ROM Required	Stress Level
Hip	Flexion, abduction/adduction	90° flexion, significant adduction ROM	🟡 Moderate
Knee	Flexion/Extension (working leg)	90-100° flexion	🟢 Low-Moderate
Ankle	Dorsiflexion (working), neutral (straight)	15-20° dorsiflexion	🟢 Low
Spine	Neutral stability	Minimal movement	🟢 Low

Mobility Requirements

Joint	Minimum ROM	Test	If Limited
Hip Adduction	Able to step 3 feet laterally with heel down	Can you do a lateral lunge without heel lifting?	Start narrower, daily adductor stretching
Ankle	15° dorsiflexion	Wall ankle test	Heel-elevated shoes, calf stretches
Hip Flexion	90°	Comfortable squat depth	Hip mobility work

Joint Health Note

Adductor flexibility is the most common limitation. If your straight leg's heel lifts no matter what you try, your adductors are too tight for your current step width. Reduce width and work on stretching over time. Forcing it risks groin strain.

❓ Common Questions

My heel lifts on the straight leg — what should I do?

Your adductors aren't flexible enough for that step width yet. Take a narrower step (reduce by 6-12 inches) until you can keep your heel down. Work on adductor stretching (frog stretch, butterfly stretch) between sessions. Progress step width gradually over weeks.

Should my straight leg be completely locked or slightly bent?

Either is fine. A completely straight leg creates more adductor stretch. A soft (slightly bent) knee is easier and still effective. Many people start with soft knee and progress to straight as flexibility improves.

Lateral lunge vs. Cossack squat — what's the difference?

They're very similar. Lateral lunge typically keeps both heels down and doesn't go as deep. Cossack squat allows the straight leg's heel to lift and goes into a deeper squat position on the working leg. Cossack is more of a mobility drill; lateral lunge is more strength-focused.

Can I do lateral lunges alternating sides continuously?

Yes! This is called "side-to-side lunges." Instead of returning to center standing position, you shift your weight from one leg to the other continuously. It's more challenging for conditioning and keeps constant tension on the muscles.

I feel this more in my quads than adductors — is that wrong?

Not wrong, just different emphasis based on your execution. To feel more adductor: widen your step, focus on pushing back to center, and really stretch the straight leg. To feel more quad/glute: focus on sitting back into the working leg hip.

Are lateral lunges good for preventing groin injuries?

Yes! They're one of the best exercises for groin injury prevention because they strengthen adductors through their full range of motion. Athletes in sports with cutting movements (soccer, basketball, hockey) especially benefit. Progress gradually to avoid causing the injury you're trying to prevent.

For Mo

When to recommend this exercise:

• User plays sports with lateral movement (basketball, soccer, tennis, hockey)
• User wants to improve hip mobility
• User has history of groin tightness/wants to prevent groin injury
• User needs frontal plane training (most people neglect this)
• User wants to build complete leg development (adductors often undertrained)

Who should NOT do this exercise:

• Acute groin strain or adductor injury → Wait for healing
• Severe hip impingement → Suggest different plane movements
• Very poor adductor flexibility AND won't modify → Risk of strain

Key coaching cues to emphasize:

1. "Both feet point forward, step out wide"
2. "Push your hips back, keep that heel down"
3. "Feel the stretch in your inner thigh, push back from your glute"

Common issues to watch for in user feedback:

• "My heel lifts on the straight leg" → Step narrower! This is the #1 issue. Cue smaller steps until flexibility improves
• "I feel off-balance" → Normal at first. Slow down, may need slightly narrower step
• "I feel a pull in my groin" → Distinguish stretch (okay) from sharp pain (stop). If sharp, they went too wide
• "I don't feel it working my inner thighs" → Likely stepping too narrow or not pushing back to center powerfully

Programming guidance:

• Pair with: Sagittal plane exercises (squats, lunges), great warm-up for leg day
• Use as warm-up: 2 sets of 8-10/leg bodyweight before leg training
• Use as strength work: 3-4 sets of 10-12/leg with load after main lifts
• Typical frequency: 2-3x per week, can be done more often as mobility work

Progression signals:

• Ready to progress when: Can perform 3x12/leg with heel down, good depth, no balance issues
• Add load when: Bodyweight is easy, mobility allows full ROM
• Progress to Cossack when: Can do wide lateral lunge with heel down comfortably
• Regress if: Heel lifting no matter what, groin discomfort, balance issues

Special considerations:

• Athletes: Almost all athletes benefit from this — it's a commonly neglected movement plane
• Mobility: This doubles as mobility work; can be used in warm-ups even on non-leg days
• Injury prevention: Excellent for groin health, but must be progressed conservatively
