Below are the 5 best abdominal exercises for a flat tummy:
1. Crunches / Sit ups
This exercise is beneficial for your upper abdomen. Lie on the floor with both knees bent and lock your palms at the base of your head to prevent a neck strain. Bend your knees with your feet on the floor. Now, lift your shoulders and upper back up and away from the floor with your face pointing toward the ceiling. Exhale as you come up as far as you can, hold for a second, then inhale as you return to the starting position. Repeat 15-20 times.
2. Twist crunches
These crunches work on your oblique muscles which is important if you want toned abdominal muscles. Start with the same position as the above exercise, but instead on crunching the regular way, crunch sideways by bringing the elbow to the opposite knee. Keep your lower back pressed onto the floor, and crunch by lifting the shoulder blades off the floor. Twist the upper body diagonally while crunching. Repeat on each side 10-15 times.
3. Hip lifts
Lie on the floor and extend your arms on the floor at your sides. Your palms facing down and your legs over your hips at 90 degrees. Feet are flexed. Now, lift your hips off the floor using your core muscles while your legs are reaching towards the ceiling. Then return to the starting position. Repeat 10-15 times.
4. Side Plank
Lie on your right side while your legs are extended and your feet and hips resting on the floor on top of each other. Your right elbow should be directly under your shoulder. With your abdominals gently contracted, lift your hips off the floor. Hold for as long as you can and then return to the starting position. Repeat two to three times, alternating sides.
5. Leg Drop
Lie on the floor and raise both legs toward the ceiling. Breathe in and tighten your abs. Exhale & slowly lower your legs as low as you can without touching the floor, but make sure not to lift your lower back. Pause and breathe in. Breathe out as you raise your legs to the starting position. Repeat 10 times.
