1. Lie flat on the bed with your legs at 90 degrees to your body. Keep your legs apart (open as far as possible) and cross them. Do it 50 times before going to bed and getting up, and exercise the muscles on the inner thigh.
2. Lie in bed and ride a bike in the air. Repeat 15. Pay attention to the complete movement of the pedal ring, and use the calf to drive the thigh movement, which can make the leg muscles tense and modify the leg lines.
Stand at attention with your hands at your sides. Bend your knees and touch your toes with both hands (don't push too hard at this time). The trick is to bend your knees, not your back muscles. Then gently return to the original position. This action takes about 3 seconds. The initial goal is to do it three times in 10 second, and then accelerate after getting used to it.
Here's to health!
