If your goal is to strengthen your core and finally tone stubborn lower belly areas this summer, the right ab exercises can make a major difference. While many workouts focus heavily on upper abs, fitness experts say targeting the lower abs and obliques is key for creating a stronger, more defined midsection.
According to trainer Andrew White, a certified personal trainer and co-founder of garagegympro.com, moves that combine controlled movement with full core engagement are especially effective because they work multiple abdominal muscles at once while also improving stability and endurance. Two standout exercises he recommends are leg raises and bicycle crunches—both classic core moves that continue to deliver serious results when done with proper form.

1. Leg Raises
For many people, the lower abs are the trickiest to sculpt. Standard crunches often miss this area, making leg raises a critical part of any core routine.
“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 with your legs straight and arms at your sides. Keeping your legs straight, lift them toward the ceiling until your hips are slightly off the floor. Slowly lower your legs back down without letting them touch the ground. Repeat for 10–15 reps, maintaining control throughout the movement.
2. Bicycle Crunches
If you want to engage multiple abdominal muscles at once, bicycle crunches are a go-to move. They combine twisting and leg movement to target both the obliques and the main abdominal muscles.
“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 your hands behind your head and legs lifted, knees bent at 90 degrees. Bring your right elbow toward your left knee while extending your right leg. Switch sides, bringing your left elbow toward your right knee. Continue alternating sides in a pedaling motion for 12–20 reps per side.
