What if there was a private gym for tweens and teens to workout under supervision. Where they can come and enjoy themselves but still work out at the same time. There would be a pool and café that served low calorie meals as well. Also the equipment would be professional. The teens would learn how to use it carefully and correctly though. This business would except ages 11-18. There would be a facility for males and a facility for females so no one feels unconftorable as well.
In a world where email and messaging abound, this age group does well to mingle with all age groups and perhaps learn about the art of conversation and how to interact. Perhaps we should look at the time they spend for physical fitness as an opportunity to connect with and learn from people who can share wisdom and help their growth process.
