- Shoulders: Engaged (not fully relaxed) — scapulae slightly retracted
- Legs: Start with straight legs or slight knee bend
- Core: Pre-tensioned, ready to initiate movement
- Head: Neutral, looking forward
Equipment Setup
| Equipment | Purpose | Alternative |
|---|---|---|

"Active dead hang — shoulders engaged, core ready to explode upward"
🔄 Execution
The Movement
- 🔝 Starting Position
- ⬆️ Raise
- ⏸️ Top Position
- ⬇️ Lower
What's happening: Dead hang with active shoulders
- Hanging from bar with straight or slightly bent arms
- Shoulders engaged, not fully relaxed
- Legs hanging straight or with slight knee bend
- Core pre-tensioned
Feel: Weight pulling down, grip engaged, core ready
What's happening: Explosive hip flexion bringing knees to chest
- Drive knees toward chest powerfully
- As knees approach chest, curl pelvis backward
- This posterior pelvic tilt is KEY — rounds lower back
- Think "tuck tailbone under" at top
- Aim to bring knees as high as possible
Tempo: 1 second (explosive)
Feel: Hip flexors and lower abs contracting hard, back rounding at top
What's happening: Maximum hip flexion with posterior pelvic tilt
- Knees at chest height or higher
- Lower back rounded (flexed spine)
- Pelvis tilted backward
- Brief squeeze at top
Common error here: Not tilting pelvis — this makes it just a knee raise, missing the core activation.
What's happening: Controlled descent to starting position
- Lower legs with control — don't just drop them
- Gradually extend hips
- Return to dead hang position
- Maintain shoulder engagement
Tempo: 2-3 seconds
Feel: Eccentric loading through hip flexors and abs
Key Cues
- "Knees to chest, then curl" — two-phase movement
- "Tuck tailbone under" — posterior pelvic tilt is essential
- "Control the descent" — no swinging or momentum
- "Shoulders stay active" — engaged throughout
Tempo Guide
| Goal | Tempo | Example |
|---|---|---|
| Strength | 1-1-3-0 | 1s up, 1s pause, 3s down |
| Hypertrophy | 1-2-3-0 | 1s up, 2s pause, 3s down |
| Power | X-1-2-0 | Explosive up, pause, controlled down |
💪 Muscles Worked
Activation Overview
Primary Movers
| Muscle | Action | Activation |
|---|---|---|
| Hip Flexors | Hip flexion — bringing knees to chest | █████████░ 85% |
| Lower Abs | Posterior pelvic tilt — curling pelvis | ████████░░ 80% |
Secondary Muscles
| Muscle | Action | Activation |
|---|---|---|
| Upper Abs | Trunk flexion support | ███████░░░ 65% |
| Obliques | Stabilization, slight rotation | ██████░░░░ 55% |
Stabilizers
| Muscle | Role |
|---|---|
| Lats | Shoulder stabilization during hang |
| Forearms/Grip | Maintaining grip on bar |
| Shoulders | Active hang position |
The posterior pelvic tilt at the top is what separates this from a regular knee raise — it fully engages the lower abs through spinal flexion.
⚠️ Common Mistakes
| Mistake | What Happens | Why It's Bad | Fix |
|---|---|---|---|
| No pelvic tilt | Just bringing knees up | Becomes hip flexor exercise only | Focus on "tucking tailbone" |
| Swinging/momentum | Using swing to lift legs | Reduces core activation | Control the movement, reset if needed |
| Dropping legs | Uncontrolled descent | Wastes eccentric training | Lower with 2-3 second tempo |
| Relaxed shoulders | Full dead hang | Shoulder strain, less control | Keep shoulders engaged |
| Partial ROM | Not bringing knees high | Less muscle activation | Drive knees to chest minimum |
Skipping the pelvic tilt — many people just do knee raises. The "tuck and curl" at the top is what makes this a Garhammer Raise.
Self-Check Checklist
- Posterior pelvic tilt at top (lower back rounds)
- Knees reach chest height minimum
- Controlled descent (no dropping)
- No swinging or momentum
- Shoulders stay engaged throughout
🔀 Variations
By Difficulty
- Easier (Regressions)
- Standard
- Harder (Progressions)
| Variation | How | When to Use |
|---|---|---|
| Hanging Knee Raise | Just knee raise, no pelvic tilt | Building base strength |

| Variation | How | Emphasis |
|---|---|---|
| Bent-Knee Garhammer | Knees bent throughout | Standard version |
| Straight-Leg Garhammer | Legs straight | More challenging |
| Variation | How | When to Use |
|---|---|---|
| Weighted Garhammer | Ankle weights or dumbbell | Need more resistance |
| Garhammer Raise + Twist | Add rotation at top | Oblique focus |
| Dragon Flag | Full body extension | Elite progression |
By Target
| Target | Variation | Change |
|---|---|---|
| Lower Abs | Standard bent-knee | Focus on pelvic tilt |
| Hip Flexors | Straight-leg version | More hip flexor demand |
| Obliques | Add twist at top | Rotate knees left/right |
| Strength | Weighted version | Add ankle weights |
📊 Programming
Rep Ranges by Goal
| Goal | Sets | Reps | Rest | Notes |
|---|---|---|---|---|
| Strength | 4-5 | 5-10 | 120-180s | Use weighted or straight-leg |
| Hypertrophy | 3-4 | 8-15 | 90-120s | Focus on time under tension |
| Endurance | 2-3 | 15-25 | 60-90s | High reps, strict form |
Workout Placement
| Program Type | Placement | Rationale |
|---|---|---|
| Core day | Primary | Main core exercise |
| Pull day | Supplementary | After vertical pulling |
| Full body | Finisher | End of workout |
Progression Scheme
When you can do 3x12-15 with perfect pelvic tilt, add ankle weights (start with 2.5-5 lbs) or progress to straight-leg version.

🛡️ Safety & Contraindications
Who Should Be Careful
| Condition | Risk | Modification |
|---|---|---|
| Lower back issues | Spinal flexion under load | Start with lying versions |
| Shoulder problems | Hanging puts stress on shoulders | Use captain's chair |
| Weak grip | May fall from bar | Use wrist straps |
| Hernia | Intra-abdominal pressure | Avoid this exercise |
- Sharp pain in lower back
- Shoulder pain during hang
- Loss of grip (falling risk)
- Hernia symptoms
Safety Tips
- Warm up shoulders and core before starting
- Use chalk or straps if grip is limiting factor
- Progress slowly — this is an advanced movement
- Don't swing or use momentum

❓ Common Questions
What's the difference between this and a hanging knee raise?
The Garhammer Raise includes a posterior pelvic tilt at the top — you curl your pelvis backward and round your lower back. A knee raise just brings the knees up without this tilt. The tilt is what fully activates the lower abs.
Should I do bent-knee or straight-leg?
Start with bent-knee. Once you can do 12-15 reps with perfect pelvic tilt, progress to straight-leg for more challenge.
My grip gives out before my abs — what do I do?
Use wrist straps, lifting grips, or switch to a captain's chair. Don't let grip limit your core training.
Is the spinal flexion safe?
Yes — controlled spinal flexion under bodyweight is safe and builds core strength. This is different from heavy loaded flexion. The posterior pelvic tilt is intentional.

When to recommend this exercise:
- User wants advanced core work
- User has access to pull-up bar
- User can already do hanging knee raises well
- User wants hip flexor and lower ab strength
Who should NOT do this exercise:
- Acute lower back injury → Wait for recovery
- Shoulder injury → Avoid hanging exercises
- Hernia → Too much intra-abdominal pressure
- Complete beginner → Start with regressions
Key coaching cues to emphasize:
- "Knees to chest, then tuck tailbone under"
- "Feel your lower back round at the top"
- "Control the descent — no dropping"
Common issues to watch for in user feedback:
- "I don't feel my abs" → Check for pelvic tilt — focus on curling pelvis
- "My grip fails first" → Suggest wrist straps or captain's chair
- "My back hurts" → Check form, may need regression
Programming guidance:
- For intermediates: 3-4 sets of 8-12 reps, 2-3x/week
- For advanced: Add weight or progress to straight-leg
- Progress when: Can do 3x12-15 with perfect pelvic tilt
