Other methods of stovepipe:
1, you can lie flat, lift your legs, and ride a bike. This action can also be sitting in a chair, it must be a hard chair, and then do it, so that your lower abdomen will be tight and you can exercise together.
2, you can also jump rope, which can lengthen the muscle lines of the legs.
If there is a lot of soft fat on your legs, you can hold the wall with one hand, stand on tiptoe slightly, and then squat down. Do not do too much. Just do two groups every day, a group of ten to twenty. This action will make your legs sore. Remember to knock on your leg after you finish, and then rub it to relax, otherwise you won't look good with a lot of muscles.
