A new study has identified a new reason why some adults don't exercise.
It's a familiar scenario in the movies - the P.E. teacher who relentlessly punishes and humiliates students to the point where what should be the favorite class becomes the most dreaded class of the day. In a movie or TV show the storyline can get big laughs.
But in real life that mean junior high or high school gym teacher can stay with you long after you graduate, according to University of Alberta Professor Billy Strean. Professor Strean interviewed dozens of adults about their fitness habits. He asked them about their attitudes toward exercise and what influenced their workout routines. Childhood experiences were the focus.
