I want to have a tighter core so that I can run and lift weights easier. What are some fast-acting exercises I can do everyday to achieve this? A flat stomach would be nice, but just tight abs will do. 
i want to do it in a normal and natural way, so if your going to suggest pills, don't answer. thigh workouts are also appreciated! thanks.
