V-shaped, then closed, then opened, then closed ... legs must be straight.

Do it every time before going to bed, and don't waste any time. I usually do it while watching the beautiful legs of models in fashion magazines, which will inspire me to do it 80~ 100 times every time. At first, I will feel very tired and sweat all over. I will rest for 20 minutes, then do it and listen to rhythmic music, so I won't work so hard. ...

This method is very good!
