How to Do Hanging Knee Raises – Benefits, Muscles Worked and Variations

This complete guide to Hanging Knee Raises will teach you everything you need to know about this effective, functional and hybrid core / grip exercise.

What are Hanging Knee Raises?

Hanging Knee Raises are a calisthenics (bodyweight) exercise that require the hips and core to work hard to hinge the lower body upwards whilst hanging from a bar.

What Muscles do Hanging Knee Raises Work?

The exercise is predominantly a core exercise; however, it also works many other muscle groups.

Rectus Abdominis

Better known as the abs, this muscle group is worked exceptionally hard by the exercise.

The rectus abdominis facilitate twisting, flexion and general movement of the torso. They connect the pelvis to the ribcage.

During the exercise they are prime movers in lifting the legs upwards.

Hip Flexors

The muscles that stimulate the movement of the legs in Hanging Knee Raises are the core and the hip flexors should only support this movement.

However, they are still a part of the movement. Just make sure that you make the abs do the vast majority of the work.


If you can’t grip the bar and hang, then you won’t be able to do Hanging knee Raises.

As a result, your grip strength will be significantly improved by this exercise.

If you wish to target your core in a slightly different way, adding a twist into your Hanging Knee Raises will also stimulate the following muscles as well.

External Obliques

These muscles are located on the sides of the upper core. They allow the torso to twist from side to side.

Internal Obliques

Situated on the lower sides of the outer stomach, they work in tandem with the external obliques to facilitate turning and twisting.

Transverse Abdominis

These are deep muscles that stretch from side to side. They are harder to see but no less important as they provide strength and stability for the torso.

What are the Benefits of Hanging Knee Raises?

This effective exercise has many benefits.

Building Six Pack Muscle Mass

Hanging Knee Raises are one of the best ways to directly target the six pack with a down-up movement (using the abs to bring the knees upwards).

If a six pack is a goal of yours then make sure to dial in your nutrition, as this is just as important.

Better Core Strength

During every rep, you must work hard to stop the body from swaying and control the lower half of the body through the full range of motion.

Both of these tasks will significantly tax and develop your core strength.

Holding yourself still whilst flexing the abs and lifting the legs is not easy to perform at the same time.

Enhanced Grip Strength

Although the movement is primarily a core exercise, it is an excellent way to also build a vice like grip.

A strong grip is a vastly underrated aspect of many athletes training programs and will help you become, and feel, stronger for numerous other exercises.

Improved Overhead Mobility

Simply handing from a bar is an excellent way to improve shoulder mobility.

As gravity pulls the body downwards, the shoulders are kept in the full overhead position at all times during each set.

How to Do Hanging Knee Raises

Use the following instructions to perform the exercise correctly.

  • Grip the bar with a pronated (palms facing forwards). Make sure they are shoulder width (or slightly wider) apart
  • Hang for a few seconds until your body is completely still
  • Set the shoulder blades back and down
  • Inhale and brace your grip, core and glutes
  • Squeeze the legs together and move into the hollow position
  • Bend the knees
  • Move the legs upwards by tensing the abs
  • Move the knees upwards until they reach at least 90 degrees
  • Slowly lower them the starting position
  • Exhale
  • Ensure that the body is completely still before starting the next rep
  • Repeat for the desired number of reps

Training Tips for Hanging Knee Raises

Experiment with different grip widths until your find the one that feels most comfortable for you.

Think of trying to pull your knees towards your spine.

Don’t use the hip flexors to facilitate the movement.

Keep the core tight and braced at all times, this will stop the body from swinging as much.

Who Should Do the Hanging Knee Raise?

The exercise is useful for many different types of athletes.

For Bodybuilders

When it comes to abs, this is a great way to target the six pack and stimulate hypertrophy.

Combine it with other abs and core exercises or scale it up into Toes to Bar if you want even more bang for your buck.

For Strength Athletes

Add Hanging Knee Raises after Squats or Deadlifts to hit your core from new angles and find any weaknesses.

Treat them as an accessory exercise and they will prove many benefits for your body and training.

You can even grip a dumbbell between your legs if you want more resistance.

They also help your ability to breathe and brace during exercises, a hugely useful skill for any lifter.

For Bodyweight and Home Gym Training

You only need a pull up bar, a beam, scaffolding or a tree to perform the exercise correctly.

This makes them versatile and accessible for many different athletes in many alternatives set ups.

How to Program Hanging Knee Raise (Sets and Reps)

Use these guidelines to program the exercise for different goals.

For Strength

Go for 3 – 5 sets of 3 – 6 reps. Rest for up to two minutes between sets.

The final few reps of each set should feel difficult and be close to fatigue. Try adding weight to the exercise to achieve the right standard for you and your personal ability level.

For Muscle Gain (Hypertrophy)

Aim for 3 – 4 sets of 8 – 12 reps. Rest for 30 – 45 seconds between each set.

Make sure you move slowly and with purpose in order to maximise time under tension.

For Newer Athletes

Build up the volume of your sets gradually over time.

You can even use partial reps.

The simple Dead Hang will help you to build up your grip strength and build confidence for the full exercise.

Hanging Knee Raises Variations

Add these variations into your training.

Lying Knee Pull In (Make it Easier)

This is a perfect choice if you aren’t yet confident or strong enough to work on the bar with the full movement.

This variation is performed whilst lying on the ground.

Hanging Straight Leg Raises (Make it Harder)

Instead of bending your knees, this variation demands that you keep your leg in a straight line at all times.

It is an effective way to build up to full Toes to Bar as well.

Hanging Leg Raises with a Twist

The twisting variation will bring your obliques much more into play and challenge your core in new and interesting ways.  

Hanging Knee Raises Alternatives

These alternatives provide similar stimulus for your body, but in new ways.

Toes to Bar

A perfect way to scale the movement up. This is for more advanced athletes.
