Movement Summary
🎯 Setup
Starting Position
- Bench position: Set up flat bench or elevated surface (16-20 inches high)
- Body position: Sit on floor with upper back against bench edge
- Barbell placement: Position barbell across hips (use hip pad if needed)
- Working foot: Plant one foot flat, hip-width from glutes, pointing forward
- Kickstand foot: Place other foot slightly behind and to the side, heel elevated, only toe/ball touching ground
- Weight distribution: 80-90% of work on working leg, 10-20% on kickstand for balance
- Shoulder position: Upper back and shoulder blades resting on bench
Foot Position Guide
| Foot | Position | Contact | Purpose |
|---|---|---|---|
| Working Foot | Flat, forward, 6-12" from glutes | Full foot contact | Does 80-90% of work |
| Kickstand Foot | Behind & to side, heel up | Toe/ball only | Provides balance support |
"One foot working, one foot helping — the kickstand is for balance only, not pushing"
🔄 Execution
The Movement
- 🔝 Starting Position
- ⬆️ Hip Drive
- ⏸️ Top Position
- ⬇️ Lowering
What's happening: Loaded position with unilateral setup
- Upper back supported on bench
- Barbell secured on hips
- Working foot flat, ready to drive
- Kickstand foot lightly touching for balance
- Hips low but not resting on ground
- Core braced
Feel: Weight on hips, most tension in working leg glute
What's happening: Driving hips up primarily with working leg
- Push through working leg heel
- Kickstand provides minimal support — mostly balance
- Drive hips toward ceiling
- Squeeze working glute hard at top
- Keep ribs down — don't overarch lower back
Tempo: 1-2 seconds
Feel: Working glute firing intensely, minimal contribution from kickstand leg
What's happening: Full hip extension on working leg, maximum glute contraction
- Hips fully extended (straight line from shoulders to working knee)
- Working glute maximally contracted
- Kickstand leg barely contributing
- Core braced, ribs down
- Working knee at ~90° angle
Hold: 1-2 second squeeze at top
Common error here: Using kickstand leg too much — it should provide only balance, not significant pushing force.
What's happening: Controlled descent maintaining unilateral emphasis
- Lower hips with control on working leg
- Maintain tension in working glute
- Kickstand still provides light support
- Don't crash down
- Stop just before hips touch ground
Tempo: 2-3 seconds
Feel: Working glute stretching and maintaining tension
Key Cues
- "Working leg does the work" — 80-90% effort from working leg
- "Kickstand for balance only" — don't push significantly with kickstand
- "Squeeze working glute at top" — unilateral peak contraction
- "Ribs down" — don't hyperextend lower back
Tempo Guide
| Goal | Tempo | Example |
|---|---|---|
| Strength | 1-1-2-0 | 1s up, 1s hold, 2s down |
| Hypertrophy | 2-2-3-0 | 2s up, 2s hold, 3s down |
| Balance/Control | 3-2-3-0 | Very slow and controlled |
💪 Muscles Worked
Activation Overview
Primary Movers (Working Leg)
| Muscle | Action | Activation |
|---|---|---|
| Gluteus Maximus | Hip extension — primary driver of thrust | █████████░ 85% |
Secondary Muscles (Working Leg)
| Muscle | Action | Activation |
|---|---|---|
| Hamstrings | Assists hip extension, knee stabilization | ██████░░░░ 55% |
| Adductors | Hip stabilization, assists hip extension | █████░░░░░ 45% |
Stabilizers
| Muscle | Role |
|---|---|
| Core | Maintains pelvic position, prevents hyperextension and rotation |
| Hip Stabilizers (Glute Med/Min) | Prevents pelvic drop and rotation |
| Erector Spinae | Spinal stabilization |
| Kickstand Leg | Minimal support for balance |
B-stance hip thrusts expose and correct side-to-side imbalances by isolating each leg, while the kickstand provides enough support to handle meaningful loads — more than full single-leg but less than bilateral.
⚠️ Common Mistakes
| Mistake | What Happens | Why It's Bad | Fix |
|---|---|---|---|
| Using kickstand too much | Both legs push equally | Defeats unilateral purpose | Lighten kickstand contact, focus working leg |
| Hips rotating | Hips twist to kickstand side | Uneven loading, poor control | Brace core, keep hips square |
| Overextending lower back | Arching back at top | Lumbar stress, less glute work | Keep ribs down, squeeze glutes only |
| Kickstand too far back | No stability support | Wobbly, unsafe | Position kickstand behind & to side for balance |
| Too much weight too soon | Form breaks down | Bilateral compensation | Reduce load, master control first |
Using the kickstand leg too much — this turns the exercise into a bilateral hip thrust. The kickstand should provide only balance support, not significant pushing force.
Self-Check Checklist
- 80-90% of work is on working leg
- Kickstand foot only lightly touching ground
- Hips stay square (no rotation)
- Ribs stay down, no lower back arch
- Working glute feels maximally engaged

📊 Programming
Rep Ranges by Goal
| Goal | Sets | Reps (per leg) | Rest | Notes |
|---|---|---|---|---|
| Strength | 3-4 | 6-10 | 90-120s | Heavier load |
| Hypertrophy | 3-4 | 10-15 | 60-90s | Moderate weight, focus squeeze |
| Imbalance Correction | 3-4 | 12-15 | 60s | Match reps on weaker side |
Workout Placement
| Program Type | Placement | Rationale |
|---|---|---|
| Lower body | After bilateral work | Unilateral accessory |
| Glute focus | Mid-workout | After heavy bilaterals |

🛡️ Safety & Contraindications
Who Should Be Careful
| Condition | Risk | Modification |
|---|---|---|
| Lower back pain | Hyperextension stress | Focus on ribs down, reduce load |
| Hip pain | Unilateral stress | Start with lighter weight, check foot position |
| Balance issues | Unstable, risk of falling | Use more kickstand support, lighter weight |
| Side-to-side imbalance | May feel very different each side | Normal — work weaker side more |
- Sharp pain in lower back, hips, or knees
- Inability to control the movement
- Hips rotating excessively
- Bench feels unstable
Safety Tips
- Start with lighter weight than bilateral hip thrusts (typically 50-70% of bilateral load)
- Master the pattern with dumbbell or bodyweight first
- Use hip pad to protect hips from barbell pressure
- Ensure bench is stable and won't slide
- It's normal for one side to feel much harder — that's the imbalance you're correcting
🦴 Joints Involved
| Joint | Action | ROM Required | Stress Level |
|---|---|---|---|
| Hip (Working Leg) | Extension | Full | 🟡 Moderate |
| Hip (Kickstand) | Stabilization | Minimal | 🟢 Low |
| Knee (Working) | Isometric hold | ~90° flexion | 🟢 Low |
| Spine | Neutral maintenance | Minimal | 🟡 Moderate (if form breaks) |
B-stance work challenges hip stability more than bilateral exercises, strengthening the smaller stabilizer muscles around the hip joint.
❓ Common Questions
How much weight should the kickstand leg support?
About 10-20% at most. The kickstand should provide just enough balance support to keep you stable, but almost all the work should be done by the working leg. If you can't tell which leg is working harder, you're using the kickstand too much.
One side feels WAY harder than the other. Is that normal?
Yes, this is very common and exactly why B-stance hip thrusts are useful. They expose side-to-side imbalances. Start with your weaker side and match reps on the stronger side, or do an extra set on the weaker side.
Should I use less weight than bilateral hip thrusts?
Yes, typically 50-70% of your bilateral hip thrust weight is a good starting point. This is normal because you're working one leg and demanding more stability.
Where should my kickstand foot be positioned?
Behind and slightly to the side of your working foot, with only the toe/ball of the foot touching. Heel should be elevated. Experiment to find what provides enough balance support without contributing significant force.
How do I progress from B-stance to single-leg?
Gradually reduce how much the kickstand foot touches the ground. Over time, use lighter and lighter contact until you're barely tapping the floor, then try removing it entirely.

When to recommend this exercise:
- User has strength imbalances between legs
- User wants to progress toward single-leg hip thrusts
- User needs unilateral glute work but single-leg is too hard
- User wants to expose and correct asymmetries
Who should NOT do this exercise:
- Acute lower back or hip injury → Wait for recovery
- Severe balance issues → Start with bilateral or use more support
- Cannot maintain form with kickstand setup → Stick with bilateral
Key coaching cues to emphasize:
- "The kickstand is for balance only — working leg does the work"
- "Keep your hips square, don't let them rotate"
- "Squeeze the working glute, not your back"
Common issues to watch for in user feedback:
- "One side feels way harder" → Normal, expose imbalance, match reps
- "I feel both legs working equally" → Using kickstand too much, reduce contact
- "My hips twist" → Brace core, slow down tempo, reduce weight
- "It feels unstable" → Adjust kickstand position, use lighter weight
Programming guidance:
- For strength: 3-4x6-10 per leg after bilateral work
- For imbalance correction: Start with weaker leg, match reps on stronger side
- Progress when: Can do 3x12 per leg with good control, minimal kickstand use
