All my family is obese except me need help (10 point reward)?

you need something dramatic. get them in2 a situation that they need 2 use their physical skills. People won't change unless something scares them in2 it, or they wanna look cooler. Maybe rent a bunch of ninja movies and hope they see it and try 2 copy everything. Maybe even reverse phycology would work! Sorry i cant give any specific answers. My dad always pushed my family 2 b more athletic. He's afraid that we'll like get in2 a bad situation in a ghetto or bar or something and die if we dont know karate.
