Leg Raise Overview
The leg raise builds strong lower abs. It works your abs most, the muscles on the front of your belly. It also works your hip flexors. Your hip flexors sit at the top of your thighs. You lie flat on your back and lift your legs up. You need no gear at all. The leg raise is great for beginners. You can do it at home on any floor. It teaches your core to stay tight. This helps your posture and a strong belly. It is a safe way to start core work. Use the leg raise on core day or at the end of a workout. Keep your lower back on the floor.
What Is The Point of the Leg Raise?
The leg raise exercise builds strong abs and develops core stability. It targets your lower abs better than most other core exercises.
How To Do The Leg Raise
- Lie flat on your back on a mat with your legs straight and together. Place your hands by your sides, or slide them palms down under your lower back for extra support if your back is sensitive.
- Press your lower back gently toward the floor and brace your core. Flattening your back removes the arch that would otherwise let your hip flexors and lower back take over.
- Set your legs straight with a slight bend in the knees if fully straight is too much for your hamstrings. Take a breath and get your abs tight before you move.
- Lift your legs slowly toward the ceiling by using your abs to control the movement. Keep them as straight as you comfortably can and avoid jerking them up.
- Raise your legs until they are roughly perpendicular to the floor, pointing straight up. Focus on curling your pelvis slightly at the top so the abs, not just the hip flexors, are working.
- Squeeze your abs hard at the top and hold for a full second. Keep your lower back pressed down so it does not arch off the floor as you pause.
- Lower your legs slowly and under control back toward the floor, taking about two to three seconds. Stop just before your feet touch the ground to keep constant tension on the abs.
- Keep your lower back flat the whole time and do not let your legs drop fast. Repeat for 10 to 20 controlled reps, keeping the core braced throughout.
Leg Raise Form Tips
- Keep your lower back pressed into the floor.
- Keep your legs straight as you lift.
- Lift with your abs, not a swing.
- Squeeze your abs at the top.
- Lower your legs slowly. No dropping.
- Stop just before your feet touch the floor.
- Keep your core tight the whole time.
- Keep your neck and shoulders relaxed.
- Breathe out as you lift. Breathe in as you lower.
Common Mistakes to Avoid for the Leg Raise
- Letting the lower back arch off the floor. When your back lifts as your legs lower, the load shifts onto your spine and hip flexors and can strain your back. Press your lower back down and brace your abs so it stays flat through the whole range.
- Dropping the legs fast. Letting your legs fall quickly uses momentum and yanks on your lower back at the bottom. Lower over two to three seconds under control so the abs resist the whole descent.
- Only working the hip flexors. If you just swing straight legs from the hips, your hip flexors dominate and the abs barely engage. Curl your pelvis slightly at the top so the abs actually work.
- Letting the feet touch and rest at the bottom. Resting your feet on the floor between reps removes tension and lets the abs relax mid-set. Stop just short of touching so the abs stay loaded the whole time.
- Using too straight a leg before you are ready. Fully straight legs create a long lever that can overwhelm a weak core and strain the back. Bend your knees slightly to shorten the lever until your core is strong enough.
- Rushing the reps. Bouncing your legs up and down fast leans on momentum and cuts the ab contraction short. Slow the movement down and control both the lift and the lower.
- Jerking the head and neck forward. Straining your neck to help does nothing for the abs and can leave it sore. Keep your head relaxed on the floor and lead the movement from your core.
- Not bracing the core. Moving your legs with a loose midsection leaves your spine unsupported and lets your back arch. Brace your abs before you lift and keep that tension throughout.
- Cutting the range short at the top. Barely lifting the legs keeps the abs from fully working. Raise your legs until they are near vertical and add the slight pelvic curl for a full contraction.
- Holding your breath through every rep. Locking your breath makes it harder to keep your core braced and can spike your pressure. Breathe out as you raise and in as you lower.
- Placing hands in a way that lets you push. Shoving hard with your hands under your hips to fling the legs up cheats the abs. Use your hands only for light support and let the abs do the lifting.
Leg Raise Workout Tips
- Use the leg raise to train the lower abs with just your bodyweight. It needs no equipment and hits the abs through a big range when you do it with control.
- Keep your lower back pressed to the floor the whole time. That single cue protects your spine and keeps the tension on your abs instead of your hip flexors.
- Add a slight pelvic curl at the top. Tilting your pelvis toward your ribs shifts the work from your hip flexors onto your abs, which is the key to making the movement count.
- Emphasize a slow, controlled eccentric. Lower your legs over two to three seconds, since resisting the descent is a major part of the ab work and protects your back.
- Bend your knees to scale the difficulty. If straight legs strain your back, a slight knee bend shortens the lever and lets you build strength safely.
- Stop just short of the floor at the bottom. Keeping your feet off the ground maintains constant tension on the abs and stops you from resting mid-set.
- Keep the reps in the 10 to 20 range. Bodyweight leg raises respond well to moderate to higher reps with strict form and constant tension.
- Slide your hands under your lower back if it is sensitive. That light support helps you keep your back flat while you learn to brace and control the movement.
- Program leg raises in a core circuit or at the end of a workout. They pair well with planks and crunches to hit the abs from several angles.
- Progress toward hanging leg raises over time. Once floor raises are easy, moving to a bar adds a bigger range and more challenge for the abs.
- Add a pause at the top for extra difficulty. Holding your legs near vertical for a second removes momentum and deepens the ab contraction.
- Film yourself from the side. It is hard to feel your back arching or your hip flexors dominating, and video shows whether your form is clean.
- Pair leg raises with an anti extension exercise like planks. Raises train the flexing job of the abs, and planks train bracing, giving you a complete midsection.
- Keep your neck and shoulders relaxed. Let the abs do the work rather than straining your neck to help lift the legs.
- Do not expect visible abs from training alone. Leg raises build the muscle, but seeing your abs depends on getting lean through your diet.
- Stay consistent and patient. Bodyweight leg raises build real core strength over time, so keep the form strict and progress the reps and range steadily.
