Secondary Muscles	Hamstrings, Calves, Core
Equipment	None (bodyweight)
Difficulty	⭐⭐ Intermediate
Priority	🟡 Accessory

Movement Summary

🎯 Setup

Starting Position

Stance: Start in lunge position, one leg forward, one back
Front knee: Bent 90°, knee over ankle
Rear knee: Bent 90°, hovering 1-2 inches above floor
Torso: Upright, chest up, core braced
Arms: Opposite arm forward (natural running position)
Feet: Hip-width apart for stability
Surface: Non-slip floor with space to move

Stance Setup

Element	Position	Why
Front foot	Entire foot flat	Stable push-off platform
Rear foot	Ball of foot	Ready to spring
Feet width	Hip-width apart	Better balance than narrow

Setup Cue

"Start in a lunge — both knees at 90 degrees, torso tall, ready to explode up"

🔄 Execution

The Movement

🔝 Starting Position
⬆️ Explosive Jump
🔄 Mid-Air Switch
⬇️ Landing
🔁 Continuous

What's happening: Deep lunge position, coiled and ready

Both knees bent 90°
Rear knee near floor (1-2 inches)
Torso upright, no forward lean
Arms in running position
Weight distributed between both legs

Feel: Legs loaded, ready to spring up

Key Cues

Primary Cues

"Explode UP" — vertical jump, not forward
"Switch in the air" — legs cycle mid-flight
"Land soft" — quiet, controlled landing
"Torso stays tall" — don't lean forward

💪 Muscles Worked

Activation Overview

Primary Movers

Muscle	Action	Activation
Quadriceps	Explosive knee extension — jumping power	`█████████░` 90%
Glutes	Explosive hip extension — driving up	`████████░░` 85%

Secondary Muscles

Muscle	Action	Activation
Hamstrings	Hip extension, landing control	`███████░░░` 70%
Calves	Ankle plantarflexion, jumping power	`████████░░` 80%
Core	Stabilizes torso during rapid leg switching	`███████░░░` 70%

Stabilizers

Muscle	Role
Hip Stabilizers	Controls landing, prevents knee collapse
Hip Flexors	Rapidly brings rear leg forward mid-air

Unique Benefit

Dynamic stability under load — the mid-air leg switch requires exceptional core control and coordination, building functional athleticism beyond standard plyometrics.

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
Landing hard	Loud, jarring impact	Joint stress, poor absorption	Focus on soft landings, bend more
Jumping forward	Traveling across floor	Not pure vertical power	Jump straight up
Incomplete switch	Legs don't fully switch	One leg works more	Complete scissor motion
Leaning forward	Torso tilts	Back strain, less power	"Chest up" throughout
Knee caving in	Knee collapses inward on landing	Knee injury risk	Push knees out
Shallow lunge	Not lowering enough	Less power development	Both knees to 90°

Most Common Error

Landing hard — this indicates poor eccentric control. If you hear loud thuds, slow down and focus on soft, controlled landings.

Self-Check Checklist

Jump vertically, not forward
Legs fully switch positions in air
Land softly and quietly
Both knees reach ~90° in lunge
Torso stays upright throughout
Knees track over toes (don't cave in)

🔀 Variations

By Difficulty

Easier (Regressions)
Standard
Harder (Progressions)

Variation	How	When to Use
Reverse Lunge	Step back without jump	Learning lunge mechanics
Alternating Lunge	Switch without jump	Building base
Jump Lunge	Jump but don't switch	Building explosive power

Variation	How	Emphasis
Continuous	No pause between reps	Cardiovascular endurance
Paused	Brief pause at bottom	Power emphasis

Variation	How	When to Use
Weighted	Hold light dumbbells	More resistance
Depth Jump Lunge	Start from elevated surface	Advanced plyometric
Lateral Jump Lunge	Switch forward/back AND side-to-side	Multi-planar power

By Training Goal

Goal	Variation	Change
Maximum Power	Paused reps, max height jump	Full recovery between reps
Endurance	Continuous, moderate pace	30-60 seconds continuous
Cardio	Fast continuous reps	HIIT-style intervals

📊 Programming

Rep Ranges by Goal

Goal	Sets	Reps (total)	Rest	Notes
Power	3-4	8-12 (4-6/leg)	90-120s	Maximum effort jumps
Endurance	3-4	20-40 (10-20/leg)	60-90s	Continuous motion
Cardio/HIIT	3-5	30-60 seconds	60-90s	Timed intervals

Workout Placement

Program Type	Placement	Rationale
Athletic training	Early in workout	Requires fresh CNS
HIIT circuit	Main exercise	High-intensity cardio
Leg day	Power work or finisher	After heavy lifting

Progression Scheme

How to Progress

Master landing mechanics first. When you can do 3 sets of 12 total reps (6 per leg) with soft, quiet landings and perfect form, add light dumbbells (5-10 lbs each) or increase reps.

Programming Notes

Do early when fresh — requires coordination and power
Quality over quantity — stop when form degrades
Full recovery — 60-120 seconds between sets
2-3x per week max — allow adequate recovery

🔄 Alternatives & Progressions

Exercise Progression Path

Regressions (Easier)

Exercise	When to Use
Reverse Lunge	Building lunge mechanics
Walking Lunge	Dynamic but non-plyometric
Jump Lunge	Building jump power without switch

Progressions (Harder)

Exercise	When Ready
Weighted Jump Lunge	Holding light dumbbells
Depth Jump Lunge	Starting from elevated platform

Alternatives

Alternative	When to Use
Scissor Jump	Similar movement, different emphasis
Box Jump	Bilateral plyometric alternative
Bulgarian Split Squat	Unilateral strength focus

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Knee pain	Landing impact stress	Avoid or use reverse lunges
Poor balance	Falling during movement	Master static lunges first
Ankle instability	Rolling ankle on landing	Build ankle strength, start slower
Low ceiling	Head contact during jump	Use lower-impact variation

Stop Immediately If

Sharp pain in knees, ankles, or hips
Inability to land softly or quietly
Dizziness or balance loss
Knee collapses inward repeatedly

Critical Safety Points

Non-slip surface essential — avoid slippery floors
Start slow — master the switch before going fast
Land soft — loud landings = poor mechanics
Clear space — ensure safe area around you
Proper footwear — supportive athletic shoes

🦴 Joints Involved

Joint	Action	ROM Required	Stress Level
Hip	Flexion/extension, explosive power	Full	🟡 Moderate
Knee	Flexion/extension, landing absorption	Full	🟠 Moderate-High
Ankle	Plantarflexion, landing control	Full	🟡 Moderate

Impact Management

The landing phase creates significant eccentric loading on all joints. Proper landing mechanics (soft, knees tracking properly) are critical for long-term joint health.

❓ Common Questions

How high should I jump?

Jump high enough to fully switch leg positions in mid-air. Focus on vertical height, not forward distance. Most people need 6-12 inches of height to complete the switch.

Should I pause between reps?

For power development, pause briefly (1-2 seconds) at the bottom. For endurance/cardio, perform continuously without pausing. Match rest to your goal.

Why do my knees hurt?

Common causes: landing hard, knee caving inward, insufficient depth, or doing too many reps. Focus on soft landings, proper knee tracking, and lower volume.

How is this different from a scissor jump?

Very similar movements. Alternating jump lunges typically emphasize deeper lunge positions (both knees at 90°), while scissor jumps may be faster and shallower. Both build explosive power.

Can beginners do this exercise?

Not recommended for true beginners. Master reverse lunges, walking lunges, and regular jump lunges before attempting the alternating version, which requires coordination and power.

For Mo

When to recommend this exercise:

User wants to build explosive leg power
User is training for sports requiring jumping/sprinting
User wants high-intensity cardio without equipment
User has mastered basic lunges and is ready for plyometrics

Who should NOT do this exercise:

Complete beginners → Start with reverse lunges
Acute knee or ankle injury → Wait for recovery
Poor landing mechanics → Master jump lunges first
Significant balance issues → Build stability first

Key coaching cues to emphasize:

"Jump straight up, switch legs in the air"
"Land soft and quiet — like a ninja"
"Chest stays up, don't lean forward"

Common issues to watch for in user feedback:

"I can't switch my legs fast enough" → Practice the switch slowly first, or use jump lunges (no switch)
"My knees hurt" → Check landing mechanics, reduce volume, ensure knees track properly
"I'm jumping forward" → Cue vertical jump, place marker on ground

Programming guidance:

For power: 3-4 sets of 8-12 total reps, 90-120s rest, early in workout
For cardio/HIIT: 3-5 sets of 30-60 seconds, 60-90s rest
Limit to 2-3x per week maximum
Progress when: Can do 3x12 with perfect soft landings
