Squat Jump
Explosive power — develops lower body explosiveness and athletic performance through plyometric training
⚡ Quick Reference
| Aspect | Details |
|---|---|
| Pattern | Squat, Plyometric |
| Primary Muscles | Quads, Glutes |
| Secondary Muscles | Hamstrings, Calves |
| Equipment | Bodyweight only |
| Difficulty | ⭐ Beginner (for plyometrics) |
| Priority | 🟠 Common |
🎯 Setup
Starting Position
- Foot position: Shoulder-width apart, toes slightly out
- Arms: At sides or ready to swing overhead
- Surface: Flat, stable ground with some cushioning
- Posture: Upright, core engaged
🔄 Execution
The Movement
- ⬇️ Loading Phase
- 🚀 Explosive Jump
- ⬇️ Landing
What's happening: Quick descent to load muscles
- Drop into quarter to half squat quickly
- Arms swing back
- Load hips, knees, ankles
- Breathing: Quick inhale
Depth: Quarter to half squat (not full depth)
What's happening: Maximum vertical jump
- Explode up — triple extension (hips, knees, ankles)
- Swing arms overhead for momentum
- Extend fully through jump
- Breathing: Explosive exhale
Goal: Maximum height
What's happening: Safe, controlled landing
- Land on balls of feet first
- Immediately absorb by bending knees
- "Stick" the landing quietly
- Reset for next rep or continuous jumps
Critical: Soft, controlled landing
Key Cues
- "Load and explode" — quick transition
- "Jump as high as you can" — maximum effort
- "Land soft like a cat" — controlled absorption
💪 Muscles Worked
Primary Movers
| Muscle | Action | Activation |
|---|---|---|
| Quadriceps | Explosive knee extension | █████████░ 90% |
| Glutes | Explosive hip extension | █████████░ 90% |
Secondary Muscles
| Muscle | Action | Activation |
|---|---|---|
| Hamstrings | Hip extension, landing absorption | ███████░░░ 65% |
| Calves | Plantarflexion, landing | ████████░░ 75% |
⚠️ Common Mistakes
| Mistake | What Happens | Why It's Bad | Fix |
|---|---|---|---|
| Squatting too deep | Slow, inefficient jump | Wastes energy | Quarter to half squat only |
| Landing stiff | High impact forces | Joint stress, injury risk | Bend knees on landing |
| Knees caving on landing | Valgus collapse | ACL injury risk | "Knees out" on landing |
| Not jumping high enough | Submaximal effort | Poor training effect | Maximum effort each rep |
| Pausing at bottom | No stretch reflex | Not plyometric | Quick transition |
Proper landing is critical — land softly, absorb impact by bending knees, avoid stiff-legged landing.

📊 Programming
Rep Ranges by Goal
| Goal | Sets | Reps | Rest | Notes |
|---|---|---|---|---|
| Max Power | 4-6 | 3-5 | 2-3 min | Quality over quantity |
| Power Endurance | 3-4 | 8-12 | 60-90s | Maintain quality |
| Conditioning | 3-5 | 15-20 | 30-60s | Circuit work |
Workout Placement
- Early in session — when fresh for power work
- After warm-up — before strength training
- Never fatigued — power requires freshness
Low volume, high quality. Focus on maximum effort, perfect landing mechanics. Rest fully between sets.
🔄 Alternatives & Progressions
🛡️ Safety & Contraindications
Who Should Be Careful
| Condition | Risk | Modification |
|---|---|---|
| Knee issues | Landing impact | Lower intensity, box jump instead |
| Ankle instability | Landing stress | Strengthen ankles first |
| Very overweight | Joint stress | Start with low box step-ups |
- Sharp joint pain
- Cannot land softly
- Knees caving on landing
🦴 Joints Involved
| Joint | Movement | ROM |
|---|---|---|
| Hip | Flexion/Extension | Full - rapid extension for takeoff |
| Knee | Flexion/Extension | 90°+ to full extension |
| Ankle | Plantarflexion | Full - pushes off ground |
Joint Considerations
- Triple extension - hip, knee, ankle extend simultaneously for maximum power
- High impact on landing - requires healthy joints
- Eccentric loading - landing creates rapid deceleration forces
The landing phase is where most injuries occur. Focus on soft, quiet landings with knees tracking over toes. If you can't land quietly, reduce jump height.
❓ Common Questions
How high should I jump? Maximum effort for power development. The goal is to jump as high as possible each rep. If you're not fully extending, you're leaving power on the table.
How many reps for power vs conditioning? Power: 3-5 reps with full rest (60-90s). Conditioning: 10-20 reps with minimal rest. Quality matters more than quantity for power.
Should I use arms? Yes. Arm swing contributes 10-20% to jump height. Drive arms up as you jump.
Can I do these every day? No. Plyometrics are high-stress on joints and nervous system. 2-3 sessions per week with 48+ hours between is sufficient.
Squat jump vs box jump? Squat jumps are simpler and require no equipment. Box jumps reduce landing impact (you land higher) but need a box. Both develop power.

When to recommend this exercise:
- User wants to develop explosive power
- Athletic performance goals
- Conditioning/fat loss circuits
- User has healthy knees and ankles
Who should NOT do this exercise:
- Acute knee or ankle injuries
- Severe joint pain
- Very overweight (high impact)
Key coaching cues:
- "Quick down, explode up"
- "Jump as high as you can"
- "Land soft and quiet"
Programming guidance:
- Place early in workout (when fresh)
- Low reps (3-5) for power, higher (10-15) for conditioning
- Full rest between sets for power work
