A small study of female college students suggests that competing against a teammate or partner helps people ramp up their exercise more effectively than if they worked out alone.
The study also found that even though participants who were paired with a strong workout partner exercised much longer, they didn't feel any more tired after the fitness bout than the people who exercised alone for a shorter period of time.
Researchers reporting in the Annals of Internal Medicine say when the goal is to exercise longer, a partner who is a little better than you are can make a big difference.
