Exercising alone can be lonely, but it may actually feel more painful. New research found that when training together members of the Oxford crew team had higher pain thresholds. Misery loves company, even in the fitness world!When paddling in a group, the rowers were able to tolerate twice as much pain than when rowing alone. I know rowing relies on intense synchrony, but there's no reason you can't tap into the group mentality during a group run or boot camp. I suggest scheduling at least one, if not more, group exercises weekly to help increase the intensity of your workouts. I know I bike farther and run faster when working out with my gal pals.
