The first statement is TRUE: it gained popularity in the 1980s with the aerobics craze.

The others are false:
- Group exercise is generally more effective for many people (better adherence, motivation) than exercising alone.
- It’s most successful with positive social support/encouragement, not negative social reinforcement.
- It was not "created" by Otto Köhler; Köhler studied group motivation (the Köhler effect) in the 1920s but did not create group exercise.
