Escaping from a straitjacket

My best friend is Puerto Rico magician Reynold Alexander. Next month, he will attempt to break the Guinness World Record of escaping from a straitjacket, while hanging from his feet 20 feet above the ground. Today I went to one of his rehearsals, and damn that's hard. The escape itself he can do it rather fast, but he's hanging from his feet! Oh, did I mentioned that the rope will be burning? He's going to the gym every day....perhaps I should do the same.

P.S.

I mean I should go to the gym, not do the escape.
