Sit-ups: Lie on the bed, cover your ears with your hands and bend your knees. Lift your shoulders off the bed with abdominal strength, then slowly put them back on the bed and repeat the operation for 20 times.
Half-bridge posture: lie on the bed, bend your knees and stand up, put your arms on your sides, then lift your hips up, control your balance with abdominal strength, breathe smoothly, and repeat the operation 15-20 times.
Side plate support: Lie on your side on the bed, support your body with one elbow and knee, and extend your other hand to the ceiling, keep your ribs open for 20-30 seconds, then twist to the other side and repeat the operation.
Although exercising in bed can reduce abdominal fat, it is recommended that you combine a healthy diet with moderate exercise to achieve better results.
