sidony,

For the most part the stage hypnosis is the same thing, but for entertainment. They volunteered to go up on stage, they willingly accept their suggestions because after-all they when there to have fun. Now I have seen stage shows where the participant refused the suggestion. Not real common, but it happens.

As far as being in hypnosis while at the gym. ABSOLUTELY!!! Athletes call it "Being in the Zone". Micheal Jordon and Tiger Woods use self hypnosis everyday!!!!
