Recommend you a sport ~ a little tired, test your endurance ~!

Lie on your back on the bed, keep your legs straight and close together, and slowly lift up at an angle of 30 with the bed.

Then stretch your arms horizontally forward, slowly lift your upper body at an angle of 30 ~ 45 with the bed, and keep your arms horizontal.

Stick to it as much as possible, it's really impossible to lie down and rest 10 seconds before doing it ~!

Stick to it for 20 minutes every day ~ ~

In less than a month, my stomach will be much flatter ~!
