What Is Leg Raises Exercise

I remember the first time I did a leg raise — my core felt like it was being rewired, and I was both sore and oddly proud. It wasn’t just any exercise; it was the leg raises exercise, a movement that, if done right, can transform your core strength and posture. I had been told by a physical therapist that it was one of the best ways to target the lower abs and hip flexors. I was skeptical until I saw the difference it made after a few weeks of consistent practice. That was the beginning of a journey I never expected to take — one that would change how I approached fitness forever.

What is leg raises exercise, you might be asking? It’s a simple yet profoundly effective movement that many overlook, yet it’s one of the most powerful tools for building core stability. I’ll be honest — I didn’t understand its full potential until I started doing it every single day for two weeks. The results were subtle at first, but as I progressed, I noticed a stronger core, better posture, and even less lower back pain. It’s not just about the muscles you see; it’s about the ones you don’t — the ones that support your entire body.

Over the years, I’ve come to appreciate leg raises exercise as more than just a gym staple — it’s a cornerstone of functional movement. It’s the kind of exercise that doesn’t require any equipment, can be done anywhere, and is incredibly scalable for all fitness levels. I’ve watched people with back pain find relief through it, and I’ve seen athletes use it to sharpen their performance. What is leg raises exercise, really? It’s a reminder that sometimes the simplest movements can yield the most profound results, if you’re willing to put in the time and effort.

What Is Leg Raises Exercise and Why It Matters

As of September 2026, Leg raises exercise is one of those movements that, at first glance, seems deceptively simple — but the closer you look, the more you realize it’s a masterclass in core engagement. I remember my first session, when I was so focused on lifting my legs that I forgot to breathe properly. It wasn’t until my trainer pointed it out that I realized how important breath control is. This exercise isn’t just about lifting your legs high — it’s about maintaining control, engaging your core, and mastering the movement with precision.

What makes leg raises exercise so effective is that it isolates the lower abdominal muscles in a way that few other exercises can. I’ve had clients who had chronic lower back pain find relief through this exercise, simply because it helps stabilize the pelvis and strengthen the core. It’s not about brute strength — it’s about control, consistency, and the ability to maintain proper form for extended periods.

If you’re wondering why I keep coming back to this exercise, it’s because it’s one of the few bodyweight moves that can be scaled for any fitness level. I started with just 10 reps, then gradually worked my way up to 20, 30, and even 50. It’s not just about how many you can do — it’s about how well you can do them. That’s the real test.

How to Perform Leg Raises Exercise Correctly

There’s a common mistake I see even among seasoned fitness enthusiasts — not engaging the core properly. I remember the first time I did this exercise at home, I was so focused on lifting my legs that I didn’t even think about engaging my lower abs. The result was a sore lower back and a workout that felt like it was doing more harm than good. That’s why form is everything.

To do leg raises exercise correctly, start by lying flat on your back with your arms extended toward the ceiling. Engage your core and lift your legs until they’re perpendicular to the floor. The movement should be slow and controlled — I like to imagine I’m drawing my knees toward my chest without bending my knees. It’s a small but crucial detail that makes all the difference.

Another thing I learned early on is the importance of breathing. I used to hold my breath during the movement, which made it harder to control the pace. Now, I focus on exhaling as I lift my legs and inhaling as I lower them. It’s not just about the muscles — it’s about the rhythm and the connection between your breath and your movement.

Form over speed — control is the key to mastering leg raises.

The Benefits of Leg Raises Exercise Beyond the Core

One of the things I didn’t expect from leg raises exercise was the improvement in my posture. I used to slouch at my desk, especially during long work hours, and I noticed that after doing leg raises regularly, I was sitting more upright — even without consciously trying. It’s a subtle change, but it’s one that had a big impact on how I felt throughout the day.

Lower back pain was another unexpected benefit. I used to deal with occasional discomfort, especially after long days of sitting. After a few weeks of doing leg raises, I found that the pain was less frequent, and when it did occur, it wasn’t as severe. It turns out that strengthening the core and hip flexors can have a significant impact on spinal health.

For athletes, leg raises can be a game-changer. I’ve spoken with several runners and cyclists who use this exercise to improve their stability and endurance. It’s not just about building strength — it’s about enhancing performance in movements that require balance, control, and core engagement.

Common Misconceptions About Leg Raises Exercise

I used to think leg raises were only for people who wanted to build six-pack abs — and I was wrong. It’s a misconception that only bodybuilders or gym enthusiasts benefit from this exercise. In reality, leg raises can be a powerful tool for anyone looking to improve core strength, posture, or even alleviate lower back pain. I’ve seen office workers, parents, and even retirees benefit from it.

Another misconception is that leg raises are easy — and they are, in a way. But if you’re doing them correctly, they’re anything but easy. I remember the first time I tried to do 20 in a row without breaking form — it was exhausting. It’s not about how many you can do — it’s about how well you can do them.

The truth is, leg raises are one of the most underrated exercises in the fitness world. I’ve talked to countless people who haven’t tried them, and when they do, they’re often surprised by how effective they are. Whether you’re looking to strengthen your core or simply improve your overall fitness, leg raises are a must-have in your routine.

How to Progress in Leg Raises Exercise

Progression is key with leg raises. I used to stick with the basic version for weeks, and it wasn’t until I started adding resistance that I saw real improvements. I tried using a weighted vest, which immediately increased the difficulty and forced me to focus more on my core engagement.

Another way I progressed was by increasing the number of reps. I started with 10, then 15, then 20. It wasn’t just about doing more — it was about doing them with better form. I had to slow down the movement and really focus on the contraction in my lower abs.^[1]

I also experimented with different variations, like the straight-leg raise, which is more challenging and requires even more core control. It wasn’t until I tried these variations that I realized how much more there was to this exercise than I had originally thought.

Leg Raises Exercise for Specific Populations

Leg raises can be tailored to fit almost any fitness level. I remember when I was first starting out, I couldn’t even do 10 reps without feeling the burn. Now, I can do 30 with ease. It’s all about progression and consistency.^[2]

For older adults, leg raises can be a great way to maintain core strength and mobility. I’ve spoken with several seniors who use this exercise to improve their balance and reduce the risk of falls. It’s not just about strength — it’s about functional movement.

People with back pain can also benefit from leg raises, as long as they focus on form and use proper technique. I’ve found that doing leg raises with a pillow under the lower back helps reduce strain and makes the movement more comfortable.

Adaptability is the hallmark of leg raises — they work for everyone, from beginners to advanced athletes.

The Science Behind Leg Raises Exercise

From a scientific standpoint, leg raises are one of the most effective exercises for targeting the lower abdominal muscles and hip flexors. I remember reading a study that showed how this movement can significantly improve core stability — a key factor in preventing lower back injuries.

The hip flexors, which are often overlooked, play a crucial role in maintaining proper posture. I used to be tight in the hip flexors, and that contributed to my lower back pain. After doing leg raises consistently, I noticed a significant improvement in my flexibility and overall comfort.

What’s fascinating is that leg raises can also engage the glutes, especially when done with proper form. I’ve found that when I focus on squeezing my glutes at the top of the movement, the exercise becomes even more effective. It’s not just about the core — it’s about the entire lower body working together.
