I believe many girls who lose weight have tried this method, but everyone may feel that the effect is not good. In fact, pedaling in the air requires us to master certain methods and essentials. First, lie flat, put your hands on your sides, then open your arms, slowly lift your legs and do pedaling. Pay attention to our knees close to the chest. Then you should lift the scapula, straighten your left leg at a 45-degree angle with the ground, twist your upper body to the right, and bring your left elbow close to your right knee.

Step 2 sit-ups

Sit-ups are the simplest and most convenient for most people, but many people's methods are not very correct. First of all, lie on the mat, hook the sofa and other auxiliary equipment with your feet, put your legs together, put your hands behind your head, contract your abdominal muscles into a sitting position, and then descend, paying attention to your back not leaving the ground, and slowly descending as much as possible, so as to better achieve the purpose of exercising your abdominal muscles.

3. Upper oblique abdomen

This method needs the help of auxiliary tools. First of all, lie on your back on an upward slope, grab the handrail on your head with both hands, and then lift your legs so that they are perpendicular to the upward slope. Feet together, spine close to the board. When you feel your body curled to the extreme, pause for 2 seconds, then slowly return to the original position and repeat it for about 20 times.
