This action is not particularly difficult to do, it is easy, just lie on the bed and stand with your legs against the wall, but in this process, you must keep your legs together and straight, otherwise it will be useless. If you are interested, you can try to practice like this for a while.
When you do this action every night, you can also read a book in your hand, so that you can get exercise. Doing this action will not waste too much time, and it is easier to stick to it. However, if you want to thin your legs by this action, the effect is very small. If you want to stovepipe, I suggest you go to the gym and find a professional personal trainer to guide you on how to train stovepipe professionally.
No matter which method you use, you need long-term exercise to really achieve the goal of stovepipe fitness. Perseverance is king, but it is precisely this that many people can't do. For example, I tried jogging at night some time ago, so the weight loss effect is very obvious, and as long as I stretch my legs for a long time after jogging, there will be no obvious calf muscles.
In a word, there are thousands of stovepipe methods in Qian Qian, but each one needs you to exercise persistently to gain something.
