🔄 Execution

The Movement

🔹 Starting Lunge Position

What's happening: Loading position

1. Both legs at ~90° angles
2. Front foot flat, back foot on ball
3. Torso upright (not leaning forward)
4. Core braced, ready to jump
5. Breathing: Inhale before jump

Position check:

• Front knee over ankle (not past toes significantly)
• Back knee hovering 1-2 inches off ground
• Weight distributed 60/40 (front/back)

Feel: Tension in front quad and glute

⬆️ Explosive Jump

What's happening: Power generation

1. EXPLOSIVELY drive through front foot
2. Simultaneously push off back foot
3. Extend both legs forcefully
4. Jump as high as possible vertically
5. Swing arms powerfully (like sprinting)
6. Breathing: Hold or forceful exhale

Tempo: MAXIMUM EFFORT (0.1-0.2 seconds)

Feel: Full leg power, driving up

Key cue: "Jump as high as you can — explode up"

↔️ Scissor Switch in Air

What's happening: Leg position change mid-flight

1. Rapidly switch leg positions while airborne
2. Front leg goes back, back leg comes forward
3. "Scissor" motion — legs pass each other
4. Arms switch simultaneously
5. Prepare for opposite-leg landing

Duration: 0.2-0.4 seconds

Feel: Quick leg switch, controlled in air

Key cue: "Scissor your legs — quick switch"

⤵️ Landing

What's happening: Absorption in lunge position

1. Land with opposite leg forward from start
2. Both feet land simultaneously
3. Immediately absorb into lunge position
4. Front foot flat, back foot on ball
5. Sink into ~90° angles on both legs
6. Torso stays upright
7. Breathing: Exhale on landing

Position: Stable lunge, ready for next rep

Feel: Controlled absorption, balanced

Key cue: "Land soft, stick the lunge"

🔁 Continuous Reps

What's happening: Immediate next repetition

1. From landing position, immediately jump again
2. No pause — continuous rhythm
3. Switch legs in air each rep
4. Maintain quality throughout set

Rhythm: Jump-switch-land-jump-switch-land

Feel: Challenging balance and power endurance

Key Cues

Primary Cues

• "Explode up, not forward" — vertical jump height
• "Quick scissor switch" — rapid leg change in air
• "Soft landing" — absorb into stable lunge
• "Upright chest" — prevents forward lean

Tempo Guide

Goal	Tempo	Example
Max Power	1-0-X-1	1s setup, explosive jump, controlled landing
Continuous Power	X-0-X-X	Fast rhythm throughout
Learning	2-1-X-2	Pause in lunge, explosive jump, controlled landing

💪 Muscles Worked

Activation Overview

Primary Movers

Muscle	Action	Activation
Quadriceps	Knee extension on front leg — primary power	█████████░ 88%
Glutes	Hip extension, stabilization	████████░░ 85%

Secondary Muscles

Muscle	Action	Activation
Hamstrings	Hip extension, deceleration	██████░░░░ 65%
Calves	Ankle plantar flexion, push-off	███████░░░ 70%
Core	Stabilize torso, prevent rotation	███████░░░ 75%

Stabilizers

Muscle	Role
Hip Stabilizers (Glute Med/Min)	Prevent hip drop, lateral stability
Core Stabilizers	Maintain upright posture mid-air and landing
Ankle Stabilizers	Balance during single-leg loading

Muscle Emphasis

Jump lunge uniqueness: Combines unilateral power development with balance challenges and metabolic demand. Excellent for exposing and correcting left/right imbalances. Higher core activation than bilateral jumps due to stability requirements.

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
Jumping forward	Travel forward instead of up	Off balance, harder to switch legs	"Jump straight up"
Torso leans forward	Chest drops on landing	Lose balance, stress on front knee	"Chest up, shoulders back"
Incomplete leg switch	Legs don't fully switch positions	Unstable landing, less effective	"Full scissor — complete the switch"
Landing stiff-legged	Straight legs on landing	Knee injury risk, hard impact	"Absorb into lunge position"
Front knee caves in	Knee collapses inward (valgus)	ACL stress, poor mechanics	"Knee out, track over toes"

Most Common Error

Jumping forward instead of up — creates forward momentum that makes landing unstable and leg switching difficult. Focus on maximum vertical jump height, allowing only minimal forward travel.

Self-Check Checklist

• Jump trajectory is vertical (not forward)
• Full leg scissor switch in air
• Land in balanced lunge position
• Torso stays upright throughout
• Front knee tracks over toes (doesn't cave)
• Both legs at ~90° on landing
• No excessive forward/backward drift

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Knee pain (anterior)	Front knee stress, impact	Use Reverse Lunge instead
Hip flexor strain	Explosive hip flexion switching legs	Reduce depth, use Split Squat
Ankle instability	Single-leg balance demands	Strengthen ankles, use Walking Lunge
Poor balance	Landing stability	Master static lunges first

Stop Immediately If

• Sharp knee pain (especially front knee)
• Hip flexor pain or pulling sensation
• Knee buckling on landing
• Repeated loss of balance/falling

Spotter Guidelines

When Needed	How to Spot
Not typically spotted	Self-limiting exercise
Beginners	Coach watches for knee alignment, balance

Safe Failure

How to safely stop jump lunges:

1. If fatigued: Simply stop jumping, step out of lunge position
2. If balance failing: Stop mid-set, don't force more reps
3. If knee pain: Stop immediately, assess
4. Landing instability: Reduce jump height or stop set

Safety Guidelines

• Master regular lunges before adding jump
• Start with lower reps (8-12 total) and build up
• Clear space around you (6-8 ft diameter)
• Non-slip surface essential
• Stop when form deteriorates (especially knee tracking)
• Progress volume gradually (high injury risk when rushed)

🦴 Joints Involved

Joint	Action	ROM Required	Stress Level
Hip	Extension/flexion	90-100° flexion to extension	🔴 High
Knee	Extension/flexion	90° flexion to full extension	🔴 High
Ankle	Plantar flexion, dorsiflexion	Full ROM	🟡 Moderate

Mobility Requirements

Joint	Minimum ROM	Test	If Limited
Hip	100° flexion, good extension	Lunge position	Reduces depth, quality
Hip flexor	Adequate length	Lunge stretch test	Back leg position suffers
Ankle	15° dorsiflexion	Lunge position	Front knee can't track forward properly

Impact Forces (Per Leg)

Phase	Force (x bodyweight)	Risk Level
Takeoff	2-3x	🟡 Moderate
Landing (good form)	3-5x	🟡 Moderate
Landing (poor form)	6-8x+	🔴 High

Joint Health Note

Front knee stress: Jump lunges place significant stress on the front leg's knee. Critical to maintain proper alignment (knee tracking over toes, not caving inward). Those with patellar tendinitis should avoid or use very low volume.

❓ Common Questions

Should I switch legs every rep or do multiple reps on one leg?

Standard technique is alternating (switch legs each rep) for continuous power-endurance. However, you can also do all reps on one leg before switching for pure power focus. Alternating is more challenging for balance and coordination, and better for conditioning.

My front knee hurts when I do jump lunges. What should I do?

Stop immediately. Knee pain often indicates: 1) Front knee traveling too far forward, 2) Landing too hard/stiff, 3) Knee caving inward. Regress to regular lunges, focus on form. If pain persists, see a professional. Jump lunges are not essential — use alternatives.

How high should I jump?

As high as possible while maintaining ability to switch legs completely and land in stable lunge position. Quality > height. If you can't switch legs fully or land unstably, you're jumping too high or too fast.

Can I do jump lunges every day?

Not recommended. Jump lunges are high-impact and neurally demanding. 2-4x per week is plenty for most people. Daily practice may lead to overuse injuries, especially in the knees. Allow 48 hours between sessions initially.

Are jump lunges better than regular lunges?

Different goals. Regular lunges: build strength and muscle with controlled movement. Jump lunges: develop explosive power and conditioning. Both have value. Most programs benefit from including both at different times.

How do I prevent jumping forward?

Common issue. Fixes: 1) Focus on jumping UP not forward, 2) Drive through your front heel, 3) Keep torso more upright, 4) Practice against a wall behind you as reference point. Film yourself from side to check.

For Mo

When to recommend this exercise:

• User wants unilateral power development
• User needs to address leg strength imbalances
• User is an athlete (basketball, soccer, tennis, running)
• User wants power + conditioning combination
• User has mastered basic lunge mechanics

Who should NOT do this exercise:

• Anterior knee pain → Suggest Reverse Lunge
• Hip flexor issues → Suggest Split Squat
• Poor balance/coordination → Start with Walking Lunge
• Acute knee or ankle injury → Avoid plyometrics
• Complete beginner → Build base with Bodyweight Lunge first

Key coaching cues to emphasize:

1. "Jump straight up, not forward"
2. "Quick scissor switch in the air"
3. "Land soft in solid lunge position"
4. "Keep chest up and proud"
5. "Front knee tracks over toes"

Common issues to watch for in user feedback:

• "My front knee hurts" → Likely poor alignment or too much volume, check form
• "I keep jumping forward" → Not driving vertically, losing balance
• "I can't switch my legs fast enough" → Jumping too fast, need to slow down
• "One leg is way harder" → Normal — use this to identify and address imbalance
• "I'm exhausted quickly" → This is metabolically demanding, normal response

Programming guidance:

• Pair with: Upper body work, bilateral power movements
• Avoid same day as: Heavy squats before (pre-fatigue), but OK after
• Typical frequency: 2-3x per week
• Volume: 15-40 total reps per session (start lower)
• Best used: Middle of workout or as conditioning finisher

Progression signals:

• Ready to progress when: Stable landings, full leg switches, good knee tracking, consistent rhythm
• Progress by: Adding reps/sets, reducing rest, adding light weight (vest), increasing tempo
• Regress if: Knee pain, poor landings, forward drift, inability to complete leg switch

Imbalance identification:

• If one leg feels significantly weaker/harder: This is valuable information
• Can program extra volume on weaker side
• Track which leg forward is harder — indicates specific weakness
