🎯 Setup

Starting Position

1. Box height: 12-18 inches (lower than forward step-ups)
   • Start lower than you'd use for forward step-ups
   • Higher box = more glute medius demand
2. Box position: Box to your side (lateral to your body)
3. Starting stance: Stand beside box, feet hip-width apart
4. Lead foot placement: Place foot closest to box flat on top
   • Entire foot on box, not just heel or toes
5. Trail leg: Foot stays on floor initially
6. Posture: Stand tall, chest up, shoulders level
7. Optional loading: Dumbbells at sides or single dumbbell goblet style

Equipment Setup

Equipment	Setting	Notes
Box/Bench	12-18" height	Lower than forward step-ups
Dumbbells (optional)	Light to moderate	10-25 lbs to start
Space	Clear lateral space	Room to step sideways safely
Surface	Non-slip	Critical for lateral movements

Setup Cue

"Stand beside the box like you're stepping up onto a curb sideways — this is all about lateral push"

🔄 Execution

The Movement

🔧 Setup Phase

What's happening: Establishing lateral starting position

1. Stand beside box with near foot on top
2. Entire foot flat on box surface
3. Far foot on ground, hip-width from box foot
4. Optional: hold dumbbells at sides
5. Big breath, brace core
6. Stand tall, shoulders level

Tempo: Controlled setup — ensure stability

Feel: Weight already shifting to box-side leg

⬆️ Lateral Push Phase

What's happening: Pushing laterally through lead leg

1. Drive through entire foot on box (emphasis on heel)
2. Push body laterally and upward
3. Minimize push from ground foot — lead leg does 90% of work
4. Breathing: Hold breath during drive up
5. Bring far leg up to meet near leg on box
6. Focus on lateral hip strength, not jumping up

Tempo: 1-2 seconds (controlled and strong)

Feel: Glute medius (side of hip) working hard, intense hip abduction

Critical: This is a LATERAL push, not a vertical jump

🔝 Top Position

What's happening: Full extension on top of box

1. Both feet on box, standing tall
2. Hips and knees fully extended
3. Core tight, shoulders level
4. Balance established before descending

Common error here: Rushing the top position. Pause briefly.

⬇️ Lowering

What's happening: Controlled lateral descent

1. Shift weight to leg that started on box
2. Lower far leg down slowly and controlled
3. Keep chest up, shoulders level throughout
4. Far foot touches floor softly on original side
5. Breathing: Exhale on the way down
6. Lead foot stays on box for next rep

Tempo: 2-3 seconds (controlled)

Feel: Eccentric load on hip abductors and glute medius

Note: All reps on one side, then switch to other side of box

Key Cues

Primary Cues

• "Push sideways, not just up" — emphasizes frontal plane movement
• "Feel the side of your hip working" — activates glute medius
• "Shoulders stay level" — prevents compensation

💪 Muscles Worked

Activation Overview

Primary Movers

Muscle	Action	Activation
Glute Medius	Hip abduction — lateral push onto box	█████████░ 95%
Glutes	Hip extension — driving upward	████████░░ 80%
Quads	Knee extension — straightening lead leg	████████░░ 75%

Secondary Muscles

Muscle	Action	Activation
Abductors	Lateral hip stability, preventing collapse	███████░░░ 70%
Adductors	Controlling lateral movement	██████░░░░ 60%
Hamstrings	Hip extension support	██████░░░░ 55%

Stabilizers

Muscle	Role
Core	Prevents lateral flexion, maintains upright torso
Hip Stabilizers	Critical for single-leg lateral balance

Muscle Emphasis

Key difference from forward step-ups: Dramatically more glute medius activation (95% vs 60%). This makes lateral step-ups essential for hip stability, knee health, and injury prevention.

To maximize glute medius: Higher box (16-20"), slow tempo, focus on lateral push To balance quad/glute work: Moderate box (12-16"), moderate tempo

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
Pushing straight up	Movement becomes vertical instead of lateral	Misses glute medius, defeats purpose	Focus on lateral push, feel side of hip
Ground foot doing too much	Pushing off ground leg	Not true unilateral training	Minimal push from ground foot
Shoulders tilting	Leaning toward or away from box	Loss of stability, compensation	Keep shoulders level, core tight
Incomplete hip extension	Not standing fully at top	Reduces ROM and muscle activation	Full lockout on top of box
Too high box	Can't control lateral movement	Injury risk, poor form	Start low (12-14"), progress slowly

Most Common Error

Jumping straight up instead of pushing laterally — this turns it into a regular step-up. The key is the LATERAL component. You should feel this intensely in the side of your hip (glute medius).

Self-Check Checklist

• Box is to your side (not in front)
• Movement has strong lateral component (not just vertical)
• Feel intense work in side of hip (glute medius)
• Shoulders stay level (no tilting)
• Lead leg does 90% of the work

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Knee pain	Lateral stress on knee	Very low box (8-10"), bodyweight only
Hip bursitis	Compression of hip bursa	Avoid or use very low box
Ankle instability	Lateral ankle roll	Lower box, strengthen ankles first
IT band syndrome	Lateral hip stress	May aggravate, assess individually

Stop Immediately If

• Sharp pain in hip or knee (not muscle fatigue)
• Feeling unstable or losing balance
• Clicking or snapping in hip
• Knee buckling or giving out

Injury Prevention

Strategy	Implementation
Start low	Use 12" box or lower initially
Progress slowly	Increase height by 2" increments only
Stable surface	Ensure box won't slip laterally
Warm up glute medius	Band walks before step-ups
Monitor knee tracking	Knee stays aligned, doesn't cave

Special Considerations

• ACL injury history: Can be beneficial for rehab (low box, controlled tempo)
• Runners: Excellent for knee health and IT band issues when done correctly
• Athletes: Critical for lateral sports (basketball, soccer, tennis)

Most Common Injury Risk

Knee valgus (inward collapse) during lateral push. This is a red flag for poor glute medius strength. If knee caves in, lower the box height and strengthen glutes before progressing.

🦴 Joints Involved

Joint	Action	ROM Required	Stress Level
Hip	Abduction/Extension	80-100° flexion, 20° abduction	🔴 High
Knee	Flexion/Extension	60-80° flexion	🟡 Moderate
Ankle	Stabilization	10-15° dorsiflexion	🟡 Moderate
Spine	Lateral stability	Minimal lateral flexion	🟡 Moderate

Mobility Requirements

Joint	Minimum ROM	Test	If Limited
Hip	90° flexion, 15° abduction	Can step laterally without shift	Hip mobility drills, glute medius activation
Knee	80° flexion	Can step onto 12" box	Knee mobility work
Ankle	15° dorsiflexion	Knee can travel forward	Ankle mobility drills

Joint Health Note

Frontal plane training is often neglected in standard programs. Lateral step-ups provide critical hip stabilization work that protects the knee and ankle. This is especially important for runners and athletes in cutting/pivoting sports.

❓ Common Questions

Why do lateral step-ups instead of regular step-ups?

Frontal plane strength. Regular step-ups are sagittal plane (forward/back). Lateral step-ups train the frontal plane (side-to-side), which targets glute medius — critical for knee health, running mechanics, and preventing IT band issues. Most people are weak in the frontal plane.

What box height should I start with?

Start with 12" or lower. Lateral step-ups are significantly harder than forward step-ups because of the glute medius demand. Even athletes should start low and progress slowly.

I don't feel my glute medius working. What am I doing wrong?

Common issues:

1. Box is too low (not enough hip abduction demand)
2. You're pushing straight up instead of laterally
3. Ground foot is helping too much
4. Glute medius is very weak (do lateral band walks first)

Focus on the lateral push component, not just getting on top of the box.

Can lateral step-ups help with knee pain?

Often yes, especially for runner's knee or IT band syndrome. Weak glute medius causes knee valgus (inward collapse), which leads to knee pain. Strengthening glute medius with lateral step-ups can reduce this. Start low and light. If pain worsens, stop and consult a professional.

How often should I do these?

2-3x per week is ideal. They're typically programmed as accessory work (2-3 sets per leg). If you're doing them for rehab/prehab, you can do them more frequently (even daily) at lower intensity.

Lateral step-up vs. lateral lunge — which is better?

Both are excellent for frontal plane strength:

• Lateral step-up: More glute medius emphasis, requires box, easier to load
• Lateral lunge: More dynamic, can do anywhere, more adductor involvement

Use both for variety, or choose based on equipment availability.

For Mo

When to recommend this exercise:

• User has knee pain (especially runner's knee, IT band syndrome)
• User is a runner or plays lateral sports (basketball, soccer, tennis)
• User's program lacks frontal plane training
• User has visible knee valgus (knees cave in during squats/lunges)

Who should NOT do this exercise:

• Acute hip or knee injury → Wait until healed, get clearance
• Severe hip bursitis → May aggravate condition
• Can't control bodyweight lateral movements → Start with lateral band walks

Key coaching cues to emphasize:

1. "Push SIDEWAYS onto the box, not just up"
2. "Feel this in the side of your hip (glute medius)"
3. "Ground foot barely helps — it's just for balance"
4. "Keep shoulders level, don't tilt"

Common issues to watch for in user feedback:

• "I don't feel it in my glutes" → Likely pushing straight up instead of laterally
• "My knee hurts" → Check for knee valgus, box may be too high
• "I feel unstable" → Box too high, start lower
• "This feels easy" → Ensure they're truly pushing laterally, may need higher box

Programming guidance:

• Pair with: Sagittal plane unilateral work (forward step-ups, split squats)
• Avoid same day as: Heavy deadlifts (glute fatigue) or multiple lateral movements
• Typical frequency: 2-3x/week, 2-3 sets per leg
• Place as accessory work after main lifts

Progression signals:

• Ready to progress when: 3x12/leg with perfect lateral push, no knee valgus
• Regress if: Knee caving in, can't control movement, pushing straight up
• Consider variation if: Mastered current height — increase by 2" only

Red flags:

• Knee caving inward → immediate correction, likely weak glute medius
• Pushing straight up instead of laterally → missing the point of the exercise
• Pain in lateral hip → possible bursitis, assess

Special note for Mo: Lateral step-ups are CRIMINALLY underused. Most programs focus only on sagittal plane (forward/back). This exercise fills a critical gap for knee health and athletic performance. Emphasize this to users with knee issues or runners.
