I am skinny and i run about half a mile, 15 pushups, 25 crunches, 15 jumping jumping jacks in the morning, after school i have soccer practice and i do all my excersises after soccer practice and games too. I am 12 years old and I am pretty much the healthiest in of my friends. I JUST FEEL LIKE IT DOES ABSOLUTELY NOTHING! People say it will work over time but it does not! I also TRY to eat healthy but it just NEVER works for me! Please help!
