Fitness trackers remain wildly popular, but do they make us fit? Maybe not, according to a study that asked overweight or obese young adults to use the tiny tracking tools to lose weight.

The 470 people in the study were put on a low-calorie diet and asked to exercise more. They all started losing weight. Six months in, half the group members started self-reporting their diet and exercise. The other half were given fitness trackers to monitor their activity.

After two years, both groups were equally active. But the people with the fitness trackers lost less weight.

No Room To Run On Miami Sidewalks

About 500 people gathered recently outside one of the only green spaces downtown: the 1300 block of Brickell Avenue.  They were the Brickell Run Club, all decked out in running shoes and workout shorts, ready to go for a run.

Once every week they run through the city. Some trips start on the corner of Southwest 13th Street and Brickell Avenue, then stretch past the Rickenbacker Causeway and back. But distance isn't the runners' only challenge. Frankie Ruiz, the club's founder, says it's hard for runners, bikers and pedestrians get through the city on foot.
