Movement Summary


🎯 Setup

Starting Position

  1. Box height: 16-20 inches for most people (knee height or slightly below)
    • Higher box = more glute emphasis
    • Lower box = more quad emphasis
  2. Barbell position: High bar or low bar on upper back/traps
  3. Starting stance: Stand facing box, feet hip-width apart
  4. Lead foot placement: Entire foot flat on box, knee aligned over toes
  5. Trail leg: Starts on floor, ready to assist minimally
  6. Posture: Chest up, shoulders back, core braced
  7. Weight distribution: Focus weight on lead leg heel

🔄 Execution

The Movement

What's happening: Establishing stable starting position

  1. Load barbell on upper back (high bar position)
  2. Step close to box, place entire lead foot flat on surface
  3. Keep trail foot on ground for balance
  4. Big breath, brace core hard
  5. Chest up, eyes forward

Tempo: Controlled setup — no rushing

Feel: Weight balanced on lead leg, core tight, ready to drive

Key Cues

Primary Cues
  • "Drive through the heel" — activates glutes, prevents knee valgus
  • "Chest up, core tight" — maintains upright posture
  • "Don't push off bottom foot" — ensures unilateral training effect

Stabilizers

MuscleRole
CoreMaintains upright torso, prevents forward lean
Hip StabilizersBalance and stability on single leg
Muscle Emphasis

To emphasize glutes: Higher box (20-24"), lean torso slightly forward To emphasize quads: Lower box (16-18"), stay more upright To improve balance: Focus on slow, controlled tempo


⚠️ Common Mistakes

MistakeWhat HappensWhy It's BadFix
Pushing off trail legTrail leg does too much workDefeats purpose of unilateral trainingFocus on driving through lead heel only
Leaning forwardTorso tilts excessivelyIncreases lower back strainChest up, core braced, eyes forward
Knee caving inLead knee collapses inwardKnee injury riskDrive knee out, engage glutes
Using momentumBouncing off trail legLess muscle activationControlled tempo, minimal trail leg push
Incomplete extensionNot standing fully at topReduces range of motionFull hip and knee lockout at top
Most Common Error

Pushing off the bottom leg — this turns it into a two-leg exercise. Focus on using the lead leg for 90% of the work. The trail leg should barely touch the ground.

Self-Check Checklist

  • Entire foot flat on box (not just toes)
  • Knee tracks over toes (doesn't cave in)
  • Chest stays upright throughout movement
  • Lead leg does nearly all the work
  • Full extension at top of movement

Progression Scheme

Progressive Overload

Progress by adding weight OR increasing box height (not both at once). Master form at current height before going higher.

🛡️ Safety & Contraindications

Who Should Be Careful

ConditionRiskModification
Knee painStress on lead kneeLower box height, reduce load
Balance issuesFall riskUse dumbbells instead, hold rail
Hip flexor strainStretch at top of movementLower box, focus on controlled tempo
Ankle instabilityAnkle roll riskEnsure stable box, lower height
Stop Immediately If
  • Sharp pain in knee (not muscle fatigue)
  • Loss of balance or feeling unstable
  • Clicking or popping in knee joint
  • Unable to control descent

Injury Prevention

StrategyImplementation
Stable surfaceUse non-slip box or bench
Proper heightStart low, progress gradually
Warm upBodyweight reps before loading
Control descentNever drop down quickly
Full foot contactEntire foot on box, not just toes

Box Safety

  • Stability: Ensure box won't slip or move
  • Height: Choose appropriate height for your mobility
  • Surface: Non-slip top surface
  • Space: Clear area around box for safety
Most Common Injury

Knee pain from improper knee tracking — ensure knee stays aligned over toes. If knee caves in, reduce weight and focus on glute activation.

Joint Health Note

Step-ups are a unilateral movement that builds balanced strength and can help identify and correct left-right imbalances. The single-leg nature also reduces overall spinal loading compared to bilateral exercises.


❓ Common Questions

What box height should I use?

Start with a box that places your thigh parallel to the ground (about 16-18" for most people). This is roughly knee height. You can go higher (20-24") to emphasize glutes or lower (12-14") for quad focus. Don't go so high that you can't control the movement.

Should I alternate legs each rep or do all reps on one side?

Do all reps on one side, then switch. This is more efficient and maintains constant tension on the working leg. Alternating each rep wastes time and reduces training effect.

How much should the trail leg help?

Minimally. The trail leg should provide just enough support for balance, but the lead leg should do 90%+ of the work. If you're pushing hard off the bottom leg, the weight is too heavy.

Step-up or Bulgarian split squat — which is better?

Both are excellent unilateral exercises:

  • Step-up: More power/concentric focus, requires box, easier to load heavy
  • Bulgarian split squat: More balance challenge, deeper stretch, can do anywhere

Use both for variety, or choose based on equipment and goals.

Can I do step-ups if I have knee pain?

Depends on the cause. Step-ups are often better than squats for knee pain because of the unilateral nature. Start with a low box and bodyweight. If pain persists, consult a professional. Avoid if you have acute knee injury.

Should I touch my back foot to the ground each rep?

Yes, touch it lightly for a reset, but don't rest or push off hard. This ensures consistent range of motion and prevents bouncing/momentum.

For Mo

When to recommend this exercise:

  • User wants to build single-leg strength
  • User has muscle imbalances between legs
  • User plays sports requiring single-leg power (running, jumping)
  • User wants to reduce spinal loading while still training legs

Who should NOT do this exercise:

Key coaching cues to emphasize:

  1. "Entire foot on box, drive through the heel"
  2. "Chest up, core tight throughout"
  3. "Trail leg barely touches — lead leg does the work"
  4. "Control the descent, don't drop"

Common issues to watch for in user feedback:

  • "I feel it in my trail leg" → Cueing issue, need to focus on lead leg only
  • "I lose balance" → Box too high, or need to use dumbbells first
  • "My knee hurts" → Check knee tracking, may need to lower box height
  • "I can't get up" → Weight too heavy or box too high

Programming guidance:

  • Pair with: Bilateral leg exercises (squats, deadlifts), posterior chain work
  • Avoid same day as: Multiple other unilateral exercises (too much balance fatigue)
  • Typical frequency: 2x/week, 3-4 sets per leg
  • Place after main compounds, before isolation work

Progression signals:

  • Ready to progress when: 3x10/leg with control, no knee cave, upright posture
  • Regress if: Can't maintain balance, knee caving in, excessive forward lean
  • Consider variation if: Mastered current height — try higher box or lateral step-up

Red flags:

  • Knee caving inward → immediate correction needed, glute activation work
  • Pushing off trail leg excessively → weight too heavy
  • Unable to control descent → reduce weight, focus on tempo
