I made it myself at home.
I have never done outdoor sports, such as running and climbing mountains, because I like staying indoors very much.
If it is stovepipe, stick to stovepipe exercise and pull the ligament. .
I just do 50 sets of cycling movements in bed before going to bed every night, and then my legs lean against the wall for 30 minutes, making a 90-degree angle with my body.
I have been insisting on it for half a month now, but it really works. I hope it works. Thank you~
