If you’ve noticed that lower belly fat seems more stubborn than ever after 40, you’re not imagining it—and you’re not alone. Hormonal shifts, changes in metabolism, and natural muscle loss can all make it harder to slim and tone your midsection. Luckily, the right exercises can make a significant difference by strengthening your core muscles, boosting fat burn, and improving your overall stability. That’s a great reason to stick to your fitness resolutions this year!
According to Andrew White, a certified personal trainer and co-founder of garagegympro.com, these four amazing exercises are especially effective for women over 40 who want to target lower belly fat in 2026. Each move focuses on engaging the right muscles to help sculpt your abs, support better posture, and build a stronger core from the inside out.
1. Leg Raises
Leg raises are an excellent abdominal exercise that can effectively tone the belly and enhance core strength. Leg raises also engage the hip flexors and the transverse abdominis, contributing to improved core stability and posture.
“A stellar move for the lower abs, which are often tougher to target. The controlled motion required to lift and lower the legs without touching the ground intensely engages the lower abdominal muscles, leading to a tighter, more toned appearance,” says White.
How to perform leg raises: Lie flat on your back, hands by your sides or under your hips for support. Keeping legs straight, lift them to the ceiling then lower back without letting them touch the ground.
2. Bicycle Crunches
Bicycle crunches are a dynamic and effective ab exercise that can significantly contribute to toning the lower belly. This exercise involves lying on your back, bringing your knees toward your chest, and alternately touching your right elbow to your left knee and your left elbow to your right knee in a pedaling motion.
“The twisting motion actively targets the obliques while the leg motion engages the rectus abdominis. Together, they provide a full abdominal workout, helping to carve out definition,” White notes.
How to perform bicycle crunches: Lie on your back with hands behind your head. Bring one knee towards your chest while twisting the opposite elbow to meet it, then switch.
3. Seated Oblique Twists
Seated oblique twists are a targeted chair exercise with a potential link to achieving a toned body and a flatter belly. This exercise focuses on engaging the oblique muscles, which play a crucial role in sculpting the waistline and supporting core strength.
“Oblique twists focus on the side abdominals, aiding in the reduction of love handles and contributing to a flatter, more toned belly,” says White.
How to perform: Sit on the edge of a chair with your feet flat on the ground. Clasp your hands in front of your chest, and twist your torso to the right, then to the left, engaging your obliques with each turn.
4. Mountain Climbers
Mountain climbers are a full-body exercise that can be especially effective for toning the lower belly. In this exercise, you start in a push-up position and then alternately bring your knees toward your chest in a running-like motion.
“This dynamic move increases the heart rate, promoting fat burn. Simultaneously, the core is actively engaged as you pull the knees in, ensuring you’re sculpting your abs,” White shares.
How to perform mountain climbers: Start in a push-up position. Bring one knee toward your chest and then quickly switch to the other knee, similar to climbing.
