Pressing your leg into a figure of eight will break your ligament.

Of course, breaking is impossible. But it may be strained! I have practiced ballet, but I was born with good ligaments. I played very standard the first time I opened my horoscope. Other students have two weeks.

But the most important thing is to suffer!

There should be no problem practicing the word "opening". Remember, leg press must practice side kick after that, which can get twice the result with half the effort.

It's hard to go to leg press alone, so it's better to ask someone for help.
