Hanging Knee Raise: Form, Muscles Worked & Progressions
How to Do a Hanging Knee Raise
Grip a pull-up bar with an overhand grip and hang with enough clearance for your feet to stay off the floor.
Set the shoulders in an active but comfortable hang and let the legs become still before starting the first rep.
Brace the abdomen and lift the knees toward the chest by flexing the hips.
As the knees rise, gently curl the pelvis upward rather than stopping the movement at simple thigh flexion.
Pause briefly at the highest controlled position without throwing the torso backward.
Lower the knees slowly until the hips are extended and the body is still again.
Repeat only while you can prevent large uncontrolled swinging.
Form Check & Technique
DO THIS (Technique Tips)
- Make the first repetition of every set intentionally slow to establish rhythm.
- Think knees up, then pelvis up for a fuller abdominal contraction.
- Use shorter sets if swinging appears late in the set.
- Train dead hangs separately if grip is consistently the first thing to fail.
- Use hanging knee raises as the bridge between floor core exercises and toes-to-bar.
AVOID THIS (Common Mistakes)
- Using a large backswing to launch every rep — Fix: Start still and control the lowering phase.
- Only flexing the hips and never moving the pelvis — Fix: At the top, add a small controlled pelvic curl toward the rib cage.
- Relaxing completely through the shoulders — Fix: Maintain an active, comfortable hang rather than hanging on passive structures.
- Racing through high reps when grip is failing — Fix: Use smaller sets and stop before the hang deteriorates.
- Throwing the head and torso backward — Fix: Keep the trunk organized and let the knees and pelvis move toward the rib cage.
- Progressing to straight-leg raises before controlling bent-knee reps — Fix: Earn the longer lever gradually.
About Hanging Knee Raise
The hanging knee raise is a bodyweight core exercise performed from a pull-up bar by lifting bent knees toward the torso while keeping the swing controlled. The rectus abdominis and obliques help control the pelvis, the hip flexors raise the thighs, and the forearms and shoulder girdle support the hang. You need a pull-up bar. It is a useful beginner-to-intermediate hanging-core exercise and a direct progression toward hanging leg raises and toes-to-bar.
Hanging Knee Raise Muscles Worked
The hanging knee raise combines hip flexion with abdominal stabilization and, when performed through a pelvic curl, trunk flexion.
- The hip flexors bring the thighs upward; the abdominal wall controls the pelvis and resists excessive lumbar extension.
- Grip, forearms, lats, and shoulder stabilizers support the hanging position throughout the set.
Sets & Reps Guidance
Technique / Learning
Technique: 2–4 sets of 5–8 reps with a full reset between reps if needed to eliminate swinging.
Strength Focus
Strength progression: 3–5 sets of 6–10 controlled reps, using a higher knee position, pause, or straighter legs as you improve.
Muscle Growth (Hypertrophy)
Muscle-building work: 3–4 sets of 8–15 reps with a deliberate pelvic curl and controlled lowering.

Exercise Variations & Alternatives
Dead Hang
Builds the grip and hanging tolerance needed before repeated knee raises.
Hanging Leg Raise
A longer-lever progression with straighter legs and greater trunk demand.
Toes-to-Bar
An advanced hanging compression skill requiring much more range and lat involvement.
Reverse Crunch
A floor-based pelvic-curl regression without grip or shoulder demands.
Plank
Master forearm plank form, deep core & transverse abdominis activation, straight body line setup, common mistakes, and hold times.

The Difference Between Lifting the Knees and Curling the Pelvis
If the rep stops when the thighs reach roughly hip height, most of the visible motion is hip flexion.
- Bringing the knees higher while gently curling the pelvis toward the rib cage increases the abdominal contribution.
- Do this without violently rounding or swinging the whole body.
How to Stop Swinging on Hanging Knee Raises
Start each set from stillness, keep the first rep deliberately slow, and control the lowering phase.
- If the legs swing behind you after each repetition, pause until the body settles instead of using the backswing to launch the next rep.
- Small sets are more useful than high counts built on momentum.
Hanging Knee Raise vs Hanging Leg Raise
The knee raise uses bent legs and therefore a shorter lever, making it easier on the trunk and grip.
- A hanging leg raise keeps the knees straighter and creates more torque as the feet move away from the hips.
- Use the knee raise first if straight-leg reps cause swinging or back position to deteriorate.
Grip as a Limiting Factor
Because every repetition happens in a full bodyweight hang, the forearms may fatigue before the abs.
- That is part of the exercise.
- Build dead-hang capacity separately rather than using straps immediately if your goal includes general grip development.
Hanging Knee Raise Benefits
The exercise trains the core while also building hanging tolerance and grip. It requires only a bar, scales naturally toward hanging leg raises and toes-to-bar, and teaches you to control the pelvis while the lower limbs move.
When to Progress to Toes-to-Bar
Move beyond knee raises when you can perform controlled sets without swinging, maintain an active shoulder position, and raise the knees high with a pelvic curl. The next steps are usually straighter-leg raises, knees-to-elbows, or strict compression drills before full toes-to-bar.
