Introduction
A strong core is the foundation of almost every movement you make whether you’re lifting weights, running, or simply maintaining good posture. With so many exercises claiming to be the “best” for building abs, it can be hard to know what actually works.
Among these, hanging knee raises have gained serious attention. You’ve probably seen them performed in gyms, often by people with impressive core strength. But are they truly the best core exercise available today?
In this guide, we’ll break down everything you need to know from benefits and proper form to comparisons with other core exercises so you can decide if hanging knee raises deserve a spot in your routine.

What Is Hanging Knee Raises?
Basic Definition and Movement Overview
Hanging knee raises are a bodyweight core exercise performed while hanging from a pull-up bar. The movement involves lifting your knees toward your chest in a controlled motion while keeping your upper body stable.
Unlike floor-based exercises, this movement challenges your core in a suspended position, forcing your muscles to work harder to stabilize your body.
Muscles Worked During Hanging Knee Raises
This exercise primarily targets:
- Rectus abdominis (six-pack muscles)
- Lower abs, which are often harder to activate
- Hip flexors, assisting in knee movement
Secondary muscles include:
- Grip strength muscles (forearms)
- Shoulders and lats, which stabilize your body while hanging
Why This Exercise Is So Popular
The popularity of hanging knee raises comes down to efficiency. With just a pull-up bar, you can train multiple muscle groups while building functional strength.
They’re also highly scalable, making them suitable for both intermediate and advanced fitness levels.
Are Hanging Knee Raises the Best Core Exercise Today?
What Makes a Core Exercise “The Best”?
Before labeling any exercise as “the best,” it’s important to define what that actually means. A top-tier core exercise should:
- Activate the abdominal muscles effectively
- Be safe and adaptable
- Offer progressive difficulty
- Improve overall functional strength
No single exercise can meet every need perfectly but some come very close.
Benefits of Hanging Knee Raises
Hanging knee raises offer several powerful benefits:
- Strong lower ab activation: Many exercises struggle to isolate the lower abs, but this movement excels at it
- Improved core stability: Your body must resist swinging, which builds control
- Upper body engagement: Grip, shoulders, and back muscles are also involved
- Functional strength: Mimics real-life movement patterns
According to fitness research, compound and functional movements tend to improve overall strength more effectively than isolated ones. You can explore more about core anatomy on
Limitations to Consider
Despite their advantages, hanging knee raises aren’t perfect:
- Require grip strength, which can be limiting for beginners
- Can strain hip flexors if done incorrectly
- Not beginner-friendly without modifications
So while they’re highly effective, they may not be ideal for everyone right away.
Hanging Knee Raises vs Other Core Exercises
Hanging Knee Raises vs Crunches
Crunches are one of the most common ab exercises, but they have limitations.
- Crunches offer limited range of motion
- Hanging knee raises provide full movement and deeper activation
If your goal is stronger, more functional abs, hanging knee raises are generally more effective.
Hanging Knee Raises vs Leg Raises
Leg raises are a more advanced variation.
- Hanging knee raises are easier and more beginner-friendly
- Leg raises provide greater intensity and challenge
Think of knee raises as a stepping stone toward leg raises.
Hanging Knee Raises vs Planks
Planks focus on static core endurance.
- Planks improve stability and endurance
- Hanging knee raises build dynamic strength and muscle control
Both are valuable, but they serve slightly different purposes.
Which One Should You Choose?
The best approach is not choosing just one. Instead:
- Combine dynamic exercises (like hanging knee raises)
- With static holds (like planks)
- And controlled movements (like crunches)
This creates a balanced and effective core routine.
How to Do Hanging Knee Raises Correctly
Step-by-Step Guide
Follow these steps for proper execution:
- Grab a pull-up bar with an overhand grip
- Hang with your arms fully extended
- Engage your core and avoid swinging
- Slowly raise your knees toward your chest
- Pause briefly at the top
- Lower your legs back down with control
Proper Form Tips
- Keep your core tight throughout the movement
- Avoid using momentum control is key
- Breathe properly: exhale as you lift, inhale as you lower
- Keep your back neutral, not overly arched
Proper form ensures maximum results while reducing the risk of injury.
Common Mistakes to Avoid
Swinging the Body
Swinging reduces tension on your core and makes the exercise less effective.
Using Momentum Instead of Strength
Fast, uncontrolled movements shift the focus away from your abs.
Incomplete Range of Motion
Not lifting your knees high enough limits muscle activation.
Overtraining
Training abs every day without rest can slow progress and cause fatigue.
Best Tips to Maximize Results
Focus on Mind-Muscle Connection
Concentrate on your abs doing the work not your hips or momentum.
Progress Gradually
Start with basic knee raises, then move to:
- Hanging leg raises
- Toes-to-bar
- Weighted variations
Incorporate Variations
Adding variety keeps your workouts effective and engaging.
Pair with a Balanced Routine
Combine hanging knee raises with:
- Planks
- Cable crunches
- Russian twists
This ensures full core development.
Who Should Do Hanging Knee Raises?
Beginners
Beginners can start with:
- Captain’s chair knee raises
- Assisted hanging variations
Intermediate Fitness Levels
At this stage, hanging knee raises are ideal for building:
- Core strength
- Muscle definition
Advanced Athletes
Advanced individuals can increase difficulty with:
- Straight leg raises
- Weighted movements
- Slower tempo reps

Frequently Asked Questions (FAQs)
Are hanging knee raises good for beginners?
Yes, but beginners may need to start with assisted versions until they build enough grip and core strength.
Do hanging knee raises target lower abs?
Yes, they are especially effective at engaging the lower abdominal muscles.
How many reps should I do?
Aim for 8–15 controlled reps per set, depending on your fitness level.
Can hanging knee raises help lose belly fat?
They strengthen your core, but fat loss depends on overall diet and calorie balance.
What equipment do I need?

Conclusion
So, are hanging knee raises the best core exercise today?
The honest answer is they are one of the best, but not the only one. They stand out for their ability to target the lower abs, improve functional strength, and engage multiple muscle groups at once.
However, the “best” exercise always depends on your goals, fitness level, and consistency. When used as part of a balanced routine, hanging knee raises can be a powerful tool for building a strong, defined core.
If you’re serious about improving your abs and overall strength, they’re definitely worth including in your workouts.
