Gritness app for Android finds group fitness activities around you, or lets you create your own
Not only that, but you can also create your own fitness group activity, and let other area people join in, watching how the group steadily grows in followers, so it's got both for trainers and trainees at the same time. Also, it's certainly better for keeping current groups alive, instead of constantly calling, emailing or messaging to coordinate the next round of physical activity.
You can pay for classes that require a fee, or monitor the number of participants that will take place in the next group effort you will be a part of. Granted, some places show a lot of activities in Gritness, and others show none, but with a growing user base this situation is likely to improve with time. In any case, if you are looking for some fitness event to join in your area, you can give Gritness a shot, and see who's running around there.
