Mirrors a bother at women’s gyms

Mirrors are as common as paint on the walls of health clubs, but what is so inspiring about watching yourself gasping and drenched in sweat?

For exercise novices, not much, says one study, which has found that women who exercise in front of a mirror feel worse than women who exercise without them.

“Placing mirrors in exercise centers may need to be reconsidered, especially in centers that are trying to attract exercise initiates,” said the study in the American Psychological Association journal Health Psychology.

The researchers at McMaster University in Hamilton, Ontario, looked at 58 sedentary women with an average age of 21. The women first answered questions about how they felt their bodies looked, how confident they were in their ability to ride an exercise bike, and what their mood was — whether, for instance, they felt “calm” or “worn out.”

The women rode the exercise bike twice, at a moderate intensity, for 20 minutes, one week apart. In one ride, they were in a mirrored room; in the other, the mirrors were covered by curtains.

After each ride, the women answered again the same sorts of questions they had answered in the beginning.

When women rode while they could watch themselves in the mirror, they wound up feeling worse than they did when they could not see themselves, the study found. For example, the mirrored rides left women feeling less calm and more fatigued.

This can’t be simply a case in which women who watch themselves exercise come away with a worse opinion of their own bodies, said researcher Kathleen Martin Ginis, an associate professor of health and exercise psychology at McMaster. These women on average were not overweight, and even women with high body-image scores felt worse after exercising in front of a mirror, she said.

Other studies had found that gazing into a mirror tends to make a person feel worse, Miss Ginis said.

It’s not just the body, either. Even without exercise, periods of staring into a mirror make people start to think about their other flaws as well. “We tend to be quite critical,” she said.

Exercise, on the other hand, tends to make people leave feeling better about themselves, and the study was designed to see if the exercise effect outweighed the mirror effect.

It did not, and the psychological tests picked that up. “This is the kind of thing where people come away thinking, ’I don’t feel that great,’” she said.

Women who hadn’t exercised before typically had low expectations of how well they would be able to exercise, and the women in this study probably felt the mirrors proved them right, the researchers said.

“If a bout of exercise leaves a sedentary woman feeling worse than before she worked out, it will be difficult to persuade her to establish a regular exercise program,” the researchers said.

That fits the experiences of Curves International, a fast-growing chain that focuses on women, especially those who are not competitive. Members don’t want mirrors, said founder Gary Heavin. “When we didn’t put them in, they could concentrate on having fun,” he said.
