7 Beginner-Friendly Flat Belly Workouts for Busy Women

According to health experts, even 10 minutes of consistent core engagement can begin reshaping your midsection and improving posture. That’s empowering news for women on-the-go who crave results without sacrificing their packed schedules. These seven flat belly workouts are designed specifically for beginners and busy women—meaning they’re quick, effective, and low on stress.

Ready to wave goodbye to endless crunches and hello to a smarter, simpler approach? Let’s dive into these practical, no-excuse workouts that fit perfectly into your day—whether you’ve got five minutes before a Zoom call or while dinner’s in the oven.

1. Standing Knee-to-Elbow Crunches

This standing ab exercise is a lifesaver when you want to stay upright but still engage those abdominal muscles. Perfect for beginners, it activates the core while being gentle on the spine and joints. It’s a dynamic move that doesn’t require a mat, making it ideal for sneaking in a quick session during a coffee break or TV time.

To perform, stand tall with your feet hip-width apart. Lift your right knee and bring your left elbow to meet it in the center, crunching through your core. Return to start and alternate sides. Aim for 15 reps per side, rest, and repeat.

This exercise works the obliques and the lower abs simultaneously. It also improves coordination and balance, which is a huge plus for beginners looking to build body awareness. The standing posture also encourages better alignment and can even help correct bad posture over time—double win!

2. Modified Plank Hold

Planks are a gold standard for core engagement, but jumping straight into a full forearm plank isn’t always realistic. The modified plank is a more approachable option that still targets all the key areas—abdominals, lower back, and shoulders—without overwhelming your body.

To begin, place your forearms on the floor and knees on the mat. Your back should remain straight, with your core tucked and glutes engaged. Hold for 15–30 seconds, gradually increasing time as you get stronger.

This move builds core stability, improves posture, and lays the foundation for more advanced variations in the future. If done consistently, modified planks can help reduce lower back pain and tone the entire midsection. Best of all, it’s totally doable even after a long day at work.

3. Seated Russian Twists (No Weights)

When you’re not quite ready for weighted versions, the bodyweight Russian twist is a fantastic way to build rotational strength. And you can do it while watching your favorite Netflix show or during a work break from your desk!

Sit on the floor with knees bent and feet flat. Lean back slightly to form a V-shape with your torso and thighs. Clasp your hands together and twist from side to side, tapping the floor near your hips each time. Perform 20 reps (10 per side).

Russian twists activate the obliques and help carve out the waistline. The rotational movement enhances spinal flexibility and strengthens muscles that support your posture and daily movement. It’s a sneaky way to build strength without breaking a sweat.

4. Standing Side Bends

Standing side bends are an underrated gem when it comes to toning the sides of your waist. They’re super simple, require zero equipment, and can be done virtually anywhere—even while brushing your teeth or waiting for your coffee to brew!

Stand tall with your arms overhead or hands on your hips. Slowly bend to one side, keeping the spine long and controlled. Return to center and repeat on the other side. Complete 10–15 reps per side.

This movement specifically targets the obliques and helps reduce the appearance of love handles. Over time, it strengthens the lateral chain of muscles that often get overlooked. Incorporating this into your morning routine can make a noticeable difference in your silhouette.

5. Lying Leg Raises

Lying leg raises are an excellent lower ab exercise that builds strength and tone in the belly without putting pressure on the neck or upper back. They’re especially great for postpartum women or those easing into core work.

Lie flat on your back with your hands at your sides or under your hips. Keep your legs straight and slowly lift them toward the ceiling, then lower them just above the ground without touching. Perform 10–12 reps, focusing on controlled movement.

This exercise targets the lower abdominals, which are often the hardest to activate. It also supports pelvic control and hip mobility. If keeping the legs straight is too difficult, bending the knees is a perfectly valid modification.

6. Glute Bridge with Ab Squeeze

Though often labeled a glute move, the bridge becomes a powerhouse for your core when paired with intentional abdominal engagement. Plus, it’s done lying down—making it a comforting but effective choice!

Lie on your back with knees bent and feet flat. Squeeze your abs and lift your hips until your body forms a straight line from shoulders to knees. Hold for a few seconds, then lower. Repeat for 12–15 reps.

This move activates the entire core, strengthens the lower back, and tones the glutes. The ab squeeze adds an extra layer of engagement, making it a full-body move that’s ideal for functional strength. It’s gentle, effective, and especially good for those with sedentary lifestyles.

7. Seated Knee Lifts

This is one of the easiest core exercises that you can literally do while sitting at your desk or on the couch. It’s discreet, simple, and surprisingly effective for activating the lower abdominal muscles.

Sit on the edge of a chair with your hands holding the sides for support. Lift both knees toward your chest while keeping your back straight. Lower and repeat for 15 reps. For added intensity, try pausing at the top of the lift.

Seated knee lifts help engage the lower core and are perfect for anyone who spends long hours sitting. It’s a beginner-friendly way to start activating those hard-to-reach tummy muscles without needing to change clothes or lie down on the floor.
