Article Correctness Is Author's Responsibility: Group exercise improves quality of life, reduces stress far more than individual work outs

Group exercise participants showed significant improvements in all three quality of life measures: mental (12.6 percent), physical (24.8 percent) and emotional (26 percent). They also reported a 26.2 percent reduction in perceived stress levels. By comparison, individual fitness participants on average worked out twice as long, and saw no significant changes in any measure, except in mental quality of life (11 percent increase).
