To force someone to do what one wants.
I have been bullied by a plumber in August (but that is another story).
Have you ever been bullied to exercise? There is a difference between being proposed new challenging exercises and being intimidated to do something you do not want to do. You know the feeling of lying in bed and thinking: "I should have done this, said that." Hindsight is 20/20.
When I train clients, I demonstrate exercises and also show the modifications so participants can work at their own fitness level. My goal is for them to feel comfortable and successful without letting them stagnate at a plateau. I need to infuse their fitness regimen with evolving moves so they will advance and see that they are getting fitter and stronger. I also want my classes to be a relaxing and enjoyable moment in people's day so they will want to continue to work out, and enjoy the marvelous side effects exercising brings. I might be "encouragingly pushy" or"pushily encouraging!" Come and try my classes to decide.
