The Best Lower Ab Exercises for a Tight Core
Tackle your core like never before with these picks for the best lower ab exercises.
How to Build the Best Lower Ab Workout
The term "lower abs" is actually a misnomer—your rectus abdominis muscle, or abdominal wall, actually covers your entire midsection and connects to your pelvis. Still, women (and men!) are constantly searching for the best lower ab exercises that will help flatten lower belly fat (not possible; that's a body composition thing, friends). PSA: No amount of lower-abs workouts will magically make your abs pop or offer the ultimate solution for how to get rid of lower belly flab.

However, these effective exercises target multiple abdominal muscles, so you'll strengthen your entire midsection—including your lower abs—with every rep. (Related: Why It's Important to Have a Strong Core Besides Looking Good)
Here's a pro tip for getting the most out of these best lower ab exercises: Focusing on the activation of your core is the key to success with these moves (and any stomach workout). In fact, one study from Hull University found that people who mentally focused on their muscles and how they were moving experienced greater muscle activity, which can result in greater strength gains over time. We've included "mind your muscle" tips with every lower ab exercise to help you maximize the results of your low ab workout.
How it works: Do the prescribed number of sets and reps for each lower ab exercise consecutively, taking a 45- to 60-second rest between sets. Perform the full lower ab workout on 3 or 4 nonconsecutive days each week. (Or pick a few of your favorite moves and add them into your regular routine.)
You'll need: A mat or towel

90-Degree Static Press
This lower ab exercise is a great way to wake up your core at the beginning of your workout or as a stand-alone exercise any time you want to squeeze in an extra lower ab workout.
How to do it: Lie faceup with knees and hips bent 90 degrees, feet flexed. Extend arms and press both palms on top of thighs. Take a deep breath in, and as you exhale, brace abs in tight, pressing lower back against the floor as you push thighs into hands, pushing back against them (note: your legs should not move). Hold for 1 count and then release. Do up to 3 sets of 10 repetitions in a row.
Make it harder: As you exhale, lift your head and shoulders off the floor as you press thighs and palms together. Lower upper body back down to the floor as you inhale.
Mind your muscle tip: During the contraction, imagine you are "zipping" your muscles from your pelvic floor up to your belly button (drawing them in tight as if trying to squeeze into a pair of low-rise jeans).

Resisted Single-Leg Stretch
This Pilates-inspired move uses the same pressing action as the static press to deepen the engagement of your abdominals. The weight of your extended leg makes this low ab exercise more challenging. (Related: Stop Searching for "How to Get Rid of Belly Flab" and Start Utilizing Our Ultimate Plan to Lose Belly Fat)
How to do it: Lie on back and bend both knees into your chest, feet flexed. Interlace fingers on top of right thigh and extend left leg out parallel to the floor. Lift head and shoulders off the floor, curling up over the top of ribcage and looking at legs. Press palms against right thigh while tipping pelvis to bring right knee in toward chest (your hands should add resistance to your leg). Switch legs and press palms against the left thigh as right leg extends parallel to the floor. That's 1 rep. Do up to 3 sets of 10 repetitions in a row.
Make it harder: Keep both legs straight, pressing against the top of thigh as one leg pulls in, and then perform a scissoring action to switch sides.
Mind your muscle tip: As you push against your thigh, imagine you are pulling your leg into your chest with your abs. Focus on feeling the extra resistance in the abs, not your thighs or hip flexors.

U-Boat
This may be a small movement, but it works your lower abdominals in a big way!
How to do it: Sit with knees bent, feet flat on the ground. Lean back to prop upper body up on elbows (your back should remain lifted), palms facing down. Brace abs in tight and lift legs into a 90-degree angle (knees should be touching), toes pointed. Slowly bring legs over to the left (both hips should remain on the ground). Keeping the 90-degree angle with legs, lower legs and then lift them up to the right, as if you were tracing a letter "U" with your knees. That's 1 rep. Do 20 reps total, alternating sides each time.
Make it harder: The longer the lever, the harder this gets, so if you want more of a challenge, try extending your legs out farther (even straightening them completely).
Mind your muscle tip: Use your breathing to help deepen the abs work: Inhale as you sweep your legs over to one side and down, and then as you come up to the other side, exhale and visualize your belly button pressing all the way back to your spine.

Reverse Plank Hover
This is another move to add to your lower ab workout that's much harder than it looks. You'll engage your abs and just about every other muscle in your body! (Got it? Next, go for the L-sit.)
How to do it: Sit with your legs extended, feet flexed, hands just outside your hips with your fingertips facing your forward. Brace your abs in tight and press down through your arms to lift your hips a few inches off of the floor. Bend your knees slightly, keeping your heels on the ground. Inhale and scoop your abs in deeper towards your back, and as you exhale, fully extend your legs and try to push your hips slightly behind your shoulders. Hold for 1 count. Bend your knees and return hips under your shoulders to gently lower to the floor. That's one rep. Repeat up to 3 sets of 10 reps.
Make it harder: Instead of lowering your hips back down to the ground in between reps, try to keep them lifted off the floor the entire set.
Mind your muscle tip: Focus on lifting and moving your hips with your abs, only using your arms and legs for assistance.

Crisscross Lift and Switch
This two-for-one Pilates move is a great lower abs exercise—but definitely works your entire core. (If you love Pilates, also try this Megaformer-inspired workout you can do with sliders.)
How to do it: Lie on back with arms at sides. Extend both legs straight up to the ceiling, crossing right leg over left, toes pointed. Brace abs in tight, inhale, and lower legs about 45 degrees. As you exhale, bring legs back into body and lift legs overhead on an angle (as if aiming to where the wall meets the ceiling behind you), lifting hips and back off the floor, pressing down with arms for support. Pause for 1 count, and then slowly roll through spine to lower hips and bring legs back to the starting position. That's 1 rep. Do up to 3 sets of 10 repetitions.
Make it easier: This move is tough, so if you can't lift your hips all the way off the floor, take your time to get stronger before attempting. Start by practicing drawing your legs up and over, and see if you can lift just a few inches off the mat and then immediately lower.
Mind your muscle tip: Your abs should remain constantly pulled in toward your back during the entire exercise. Use the visual of "zipping" your muscles in from your pelvis up to your belly button as you lift your legs overhead.

Inching Elbow Plank
You'll feel every inch of this plank in your abs — along with your arms and shoulders too. (Try these other plank variations in our 30-Day Plank Challenge for more strong-core work too.)
How to do it: Begin in an elbow plank position, hands clasped, with feet slightly wider than hip-width apart. Step left foot toward hands as you begin to lift hips up slightly, quickly taking another step in with right foot, lifting hips a little more. Step the left foot in again, lifting hips higher and then again with the right, so hips end lifted high in a pike position. Slowly inch back out, reversing the way you walked in, until you return to the starting plank pose. That's 1 rep. Do up to 3 sets of 5 reps.
Make it harder: Take larger steps in to raise your hips even higher in the pike position, and increase the number of reps per set from 5 to 10.
Mind your muscle tip: Your abs should be drawn in during this entire lower abs exercise. As you step your foot in, think of bracing your abs in deeper with each step.

Full Plank Passé Twist
Engage those hard-to-target obliques with this dynamic twist on the traditional plank. (Then head over here for more of the best obliques exercises.)
How to do it: Begin in a full plank position with feet together. Bend right knee across to the left as you slide right foot up to the inside of left knee into a passé position (your hips should turn to the left and you'll pivot slightly on the ball of your left foot). Slide right leg back to starting position and then repeat to the left. That's 1 rep. Do up to 3 sets of 10 reps.
Mind your muscle tip: Imagine your abs are drawing your knee up and across your body. Pull your abs in tighter as you lift your leg.

Frog Press
This lower ab workout move targets your core and your inner and outer thighs all at once (just like these 11 exercises that can offer a bonus burn!).
How to do it: Lie faceup with knees bent and turned out, feet flexed, and heels pressed together. Inhale and lift head and shoulders off the floor, curling up over ribcage, looking at legs. Reach arms outside of hips off of the floor, palms facing down. As you exhale, press out through heels and extend legs 45 degrees, squeezing the backs of knees together. Inhale and bend heels back into body. That's 1 rep. Do up to 3 sets of 10 reps.
Make it harder: Extend your legs lower to the ground as you press out, or keep both legs extended and turned out, and then lift and lower them instead of bending and extending—just be sure your back stays down during the movement!
Mind your muscle tip: Focus your attention on your abs, forcing them to do most of the work to lift and lower your legs. Be sure to keep your lower back pressed into the floor the entire time.
